Streszczenie:

Of the Atlantic istiophorid billfishes, larval age–size relationships and growth rates have been examined only for blue marlin (Makaira nigricans). Using otolith microincrement analysis, we describe age–length and age–weight relationships for larval sailfish (Istiophorus platypterus) collected from the Straits of Florida. Sagittae and lapilli were dissected from 70 larvae ranging from 2.8 to 15.2 mm in (notochord or standard) length. Comparisons between otolith images obtained by light microscopy and scanning electron microscopy indicated that increment widths were well within the resolving power of light microscopy. Indirect evidence and published descriptions of larval blue marlin otoliths suggest daily increment deposition. Estimated ages of specimens ranged from 3 to 18 days. Length data were fitted to age estimates with an exponential model (R2 = 0.85). The estimated size-at-hatch for sailfish was 1.96 mm notochord length, and the daily instantaneous growth coefficient was 0.14. A power curve with exponent 3.05 described the length–dry weight relationship for sailfish. The instantaneous growth coefficient for an exponential regression of dry weight, converted from length, versus estimated age was 0.41. Growth in the length of sailfish larvae from the Straits of Florida was very similar to that described for blue marlin larvae from Exuma Sound, Bahamas.

Streszczenie:

Meta-analysis (inverse-variance, random-effects model) involving 46 studies was used to estimate the effect size of postrelease mortality (Fr) in six istiophorid billfish species (black marlin (Istiompax indica), blue marlin (Makaira nigricans), longbill spearfish (Tetrapturus pfluegeri), sailfish (Istiophorus platypterus), striped marlin (Kajikia audax), and white marlin (Kajikia albida)) following release from recreational, longline, and harpoon fishing gears. The studies involved 400 reporting pop-up satellite archival tags and 64 reporting acoustic (ultrasonic) tags. Despite fish being captured, tagged, and released under widely disparate conditions, locations, and gear types, Fr was homogeneous among species. Variability in Fr was principally due to random sampling error within studies with no evident patterns. Fifteen studies (33% of tags) indicated no mortality, and the overall summary effect size for Fr was 13.5% (95% CI: 10.3%–17.6%). Since the random-effects model decomposed to a fixed-effect model when the between-studies variance T2 = 0.00, results were confirmed using exact nonparametric inferential tests and sensitivity analyses. Our results support earlier findings in the Atlantic and substantiate the majority of istiophorid billfish survive when released from recreational and longline fishing gear, clearly implying catch-and-release as a viable management option that permits fishing activity while protecting parental biomass and the fishery.

Streszczenie:

The sailfish Istiophorus platypterus is one of the most common billfish species in the Mexican Pacific. Information about its feeding habits in the coastal region of Acapulco, Guerrero is extremely limited. In the present study we quantified the diet of sailfish, based on captures made from March 2008 to December 2009 by the sport fishing fleet of Acapulco. We analysed a total of 561 stomachs, of which 254 contained food (45%). The size interval of examined specimens was between 101 and 212 cm postorbital length and between 15 and 47 kg total weight. In general, teleosts were the most important prey, followed by cephalopods. According to index of relative importance, the most important species in the diet were the fish Auxis thazard (63.04%) and Fistularia commersonii (6.62%), followed by the cephalopod Octopus spp. (4.58%). There were no significant differences in the diet by sex (males and females), sexual maturity (immature and mature), or by season (warm and cold seasons). In all cases the most important prey species was A. thazard. We conclude that the sailfish I. platypterus off Acapulco behaves as a specialist predator because, despite the consumption of a high number of prey items, it feeds preferentially on a reduced number of prey species that form schools, and are available and abundant in the ocean.

Streszczenie:

The sailfish Istiophorus platypterus is a circumglobal billfish species. It is commonly targeted in recreational fisheries and caught as by-catch in commercial fisheries, and therefore fisheries management would benefit from an enhanced understanding of basic patterns of the species’ daily and seasonal movements. Between 2002 and 2007, 87 billfish were tagged with pop-off satellite archival tags in the Atlantic waters off the coast of South Carolina, USA, including sailfish (n = 54), blue marlin Makaira nigricans (n = 15), and white marlin Kajikia albida (n = 18). Only fish meeting specific tag program criteria and length of tag attachment were selected for further analysis (sailfish, n = 19; blue marlin, n = 4; white marlin, n = 3). Differential horizontal and vertical movement patterns were observed within sailfish by season. Two- and three-dimensional (3D) analyses showed differential spatial niche use by sailfish. Among the istiophorid species, 3D analysis showed less overlap when occupying similar horizontal areas. The results from this study, in conjunction with similar studies from other areas, provide a better understanding of habitat usage that can be applied to address uncertainties in ecology or management, such as characterization of stock structure, identifying potential spawning habitat or intra-specific competition, providing correction factors for indices of abundance, and characterizing vulnerability to fishing gear.

Abstract Fish catch species provide essential information for marine resource management. Some international organizations demand fishing vessels to report the species statistics of fish catch. Conventionally, the statistics are recorded manually by observers or fishermen. The accuracy of these statistics is, however, questionable due to the possibility of underreporting or misreporting. This paper proposes to automatically identify the species of common tuna and billfish using machine vision. The species include albacore (Thunnus alalunga), bigeye tuna (Thunnus obesus), yellowfin tuna (Thunnus albacares), blue marlin (Makaira nigricans), Indo-pacific sailfish (Istiophorus platypterus), and swordfish (Xiphias gladius). In this approach, the images of fish catch are acquired on the decks of fishing vessels. Deep convolutional neural network models are then developed to identify the species from the images. The proposed approach achieves an accuracy of at least 96.24%.

Seasonal variation of proximate composition (moisture, protein, fat and ash) of Istiophorus platypterus was analysed for one year (January 2016 to December 2016) from Visakhapatnam fishing harbor, east coast of India. The results indicated that the proximate composition of the fish depends on season. The total mean values of moisture percentage was found more in monsoon (78.36±0.09) season, followed by pre-monsoon (77.90±0.12) and post-monsoon (77.81±0.17), whereas protein content was found more in pre-monsoon (18.38±0.09) season followed by monsoon (17.45±0.09) and post-monsoon (16.52±0.09) season, the fat percentage was accumulated more in the season of post-monsoon (2.15±0.07) followed by pre-monsoon (2.13±0.12) and monsoon (1.81±0.10), while ash content observed high in post-monsoon (3.15±0.16) followed by monsoon (1.97±0.08) and pre-monsoon (1.46±0.150 season respectively.

Abstract Hoolihan, J. P. and Luo, J. 2007. Determining summer residence status and vertical habitat use of sailfish (Istiophorus platypterus) in the Arabian Gulf. – ICES Journal of Marine Science, 64. Pop-up satellite archival tags (PSATs) were deployed on 18 sailfish in the Arabian Gulf between 2001 and 2005 to determine summer geoposition and habitat preference. Programmed releases following periods ranging from 110 to 156 d provided an aggregate total of 533 monitoring days of data. Three PSATs failed to report and nine released prematurely after periods ranging from 3 to 93 d. Four were recovered in gillnets after periods ranging from 39 to 90 d, and two transmitted after programmed releases of 127 and 128 d. Pooled archival data from recovered PSATs showed a cumulative mean distribution of 83.9% for total time spent in the upper 10 m, with no significant difference between day and night (χ24 = 0.84, p = 0.93). Depth ranged from 0 to 61 m, and ambient water temperature from 19.7°C to 30.1°C. Linear displacements ranged from 11 to 543 km and were all located inside the Gulf. Satellite- and light-level-derived geopositioning suggested that all fish remained in the Gulf. The two PSATs releasing on schedule validated summer residence inside the Gulf, providing further evidence in support of genetic analyses and conventional mark-recapture studies, which suggested that this billfish population confines itself year-round within a shallow marginal sea area. Preference for near-surface depths suggests a great susceptibility to capture by gillnets and other surface gears, raising concern for the effectiveness of regional management and conservation of the species.

This paper presents a historical overview of the assessments of the Atlantic stocks of blue marlin (Makaira nigricans), white marlin (Tetrapturus albidus) and sailfish (Istiophorus platypterus) that have been conducted by the International Commission for the Conservation of Atlantic Tunas between 1977 and 2000. Details are presented on the data sets used and the models applied, noting the strengths and weaknesses of the assessments. The major causes of uncertainty in the current perception of the status of the stocks are related to some of the data used and to their interpretation, especially historical trends in catch per unit effort. In particular, there are uncertainties about historical catch data, including discards, and about the degree to which longline fishing effort overlaps with billfish habitat. The paper concludes with an account of the efforts that should be made to reduce these uncertainties.

The aim of this study was to analyze the oceanic recreational fishing in the Royal Charlotte Bank, state of Bahia, Brazil. Only data from an oceanic recreational fishing operator based in the municipality of Canavieiras, southern Bahia, were used, from 2012 to 2017. Overall, 103 fish specimens were caught and released, during this period, belonging to the following species: Makaira nigricans, Kajikia albida, and Istiophorus platypterus. Fishery operations occurred from October to March, with the highest catch in number in December (56.3%). The largest annual catch was recorded in 2013, with 39 individuals. The catch per unit effort ranged from 1.0 to 1.4 fishes per trip, with the highest value in December. Even though data presented here are partial, they can help to establish a strategic scenario for the fishing sector in Bahia, along with data from other fishing sectors (artisanal, industrial, subsistence and scientific).

Pop-up satellite archival tags (PSATs) were deployed on four sailfish, Istiophorus platypterus, in the coastal waters of Rio de Janeiro State in southeast Brazil during January and February of 2009 (sailfish I and II) and between November 2010 and January 2011 (sailfish III and IV). The total number of days monitored (i.e., time that the tags remained attached) were 12 (sailfish I), 51 (sailfish II), 16 (sailfish III) and 43 days (sailfish IV). The results indicate a clear pattern of vertical habitat utilization with the majority of the time spent concentrated near the uniform sea surface layer occupying a relatively narrow temperature range. Despite the clear preference for epipelagic surface waters, sailfish regularly undertook vertical excursions into deeper waters (>50 m) within three to six hour intervals. "Most Probable Tracks" (estimated from raw geolocations using the state-space Kalman filter model) and linear displacements suggested that tagged sailfish did not move significant distances from the tagging site. In brief, our report provides information regarding the biology of sailfish in the southwestern Atlantic and how vertical distributions during the day and night are influenced by water temperature and how this information can improve sailfish stock assessments in southwestern Atlantic Ocean.

Exuma Sound is a semi-enclosed body of water bounded by islands of the Bahamas. During July 2000, sampling for larval billfish was carried out throughout the Sound's surface waters as well as in adjacent open waters of the Atlantic Ocean. A total of 99 larval billfish (Istiophoridae) was collected. Ninety of the larvae were identifiable as blue marlin (Makaira nigricans) and three as sailfish (Istiophorus platypterus). The remaining larvae were also istiophorids, unidentified to species owing to damage; no larval Xiphias gladius were collected. Larval blue marlin densities ranged from 0 to 3.4 larvae/1000 m2; their sizes ranged from 3.1 mm notochord length to 22.6 mm standard length. Densities tended to be highest north-east of the Sound's central axis, especially within the two regions where exchange with the Atlantic is greatest. Mean densities tended to decrease in the direction of mean flow; mean lengths increased from 8.08 mm at the Sound's mouth to 14.7 mm standard length at its upper reaches. Length-based estimates of larval age ranged from 2.2 to 17.2 days. Given these age estimates and assuming passive surface transport, the blue marlin larvae collected were likely the result of recent spawning in waters that include Exuma Sound and may extend some 200 km south-east of its mouth. This study suggests that Exuma Sound functions as a nursery area for blue marlin, and possibly other billfish species, at least during the summer. Limited sampling just outside Exuma Sound, in the Atlantic Ocean proper, also yielded blue marlin larvae.

Billfishes are generally considered as by-product in tuna long line fisheries that have high economic value in the market. By far, the information about Indian Ocean billfish biology and fisheries especially in Indonesia is very limited. This research aimed to elucidate the estimation of production and size distribution of billfishes landed in port of Benoa during 2010 (February – December) through daily observation at the processing plants. The result showed that the landings dominated by Swordfish (<em>Xiphias gladius</em>) 54.9%, Blue marlin (<em>Makaira mazara</em>) 17.8% and Black marlin (<em>Makaira indica</em>) 13.0% respectively, followed by small amount of striped marlin (<em>Tetrapturus audax</em>), sailfish (<em>Istiophorus platypterus</em>), and shortbil spearfish (<em>Tetrapturus Angustirostris</em>). Generally the individual size of billfishes range between 68 and 206 cm (PFL), and showing negative allometric pattern except on swordfish that was isometric. Most of the billfish landed haven’t reached their first sexual maturity.

We present evidence of a novel form of group hunting. Individual sailfish ( Istiophorus platypterus ) alternate attacks with other group members on their schooling prey ( Sardinella aurita ). While only 24% of attacks result in prey capture, multiple prey are injured in 95% of attacks, resulting in an increase of injured fish in the school with the number of attacks. How quickly prey are captured is positively correlated with the level of injury of the school, suggesting that hunters can benefit from other conspecifics' attacks on the prey. To explore this, we built a mathematical model capturing the dynamics of the hunt. We show that group hunting provides major efficiency gains (prey caught per unit time) for individuals in groups of up to 70 members. We also demonstrate that a free riding strategy, where some individuals wait until the prey are sufficiently injured before attacking, is only beneficial if the cost of attacking is high, and only then when waiting times are short. Our findings provide evidence that cooperative benefits can be realized through the facilitative effects of individuals' hunting actions without spatial coordination of attacks. Such ‘proto-cooperation’ may be the pre-cursor to more complex group-hunting strategies.

AbstractAnalysing hourly behavioural patterns of Pacific sailfish, Istiophorus platypterus, provide an ecological perspective relative to their exploitation. In the Pacific off Central America, sailfish sustain important recreational fisheries while impacted as bycatch in commercial tuna fisheries. Given their susceptibility and potential for overexploitation, it is important to define their behavioural activity to better regulate exploitation patterns. In this study, we discuss concepts of sailfish vision related to light availability and its role on successful foraging patterns. For this purpose, activity patterns were analysed using data collected by satellite tags equipped with accelerometers and, separately, recreational fishery statistics from the region. Data are incorporated with physical and ecological information to offer a means of analysing hourly habitat use. The results reveal a positive photokinetic response to sunlight in both sailfish acceleration activity and recreational fishery statistics. Tagged sailfish also showed this activity increase as a response to full moon light. Such information is further integrated with knowledge of intra-species relationships and other key species within the pelagic fish community. Findings on daily behaviour allow the drawing of some generic conceptualizations that aid understanding of sailfish community dynamics in the region.

Billfishes area by cacth of tuna long line vessels in Indian Ocean. Billfish are consist of swordfish <em>Xiphias gladius</em>, black marlin <em>Makaira indica</em>, indo facific blue marlin <em>Makaira mazara</em>, stripe marlin <em>Tetrapturus audax</em>, indo facific sailfish <em>Istiophorus platypterus</em> and shortbill spearfish <em>Tetrapturus angustirostris</em>. Besides that, billfishes also have important economic value compared with tuna as an exsported species such as swordfish and marlin. To optimize the catch of billfishes in Indian Ocean, data and information of potential fishing ground, size and catch composition of this species are needed. The billfishes cacth composition collected in 2011 were dominated by 45% swordfish, 20% black marlin, 19% blue marlin,9% short bill spearfish, 6% sailfish and 1%stripe marlin. The billfishes size range which were caught between 60 - 280 cm LJFL (Lower Jaw Fork Length). The sword fish average length was 150 cm, blue marlin 197 cm, black Marlin 189 cm, sailfish 150cm ,short bill spearfish 144 cm and stripe marlin159 cm. From this observation, it was found that most of billfishes caught were in mature.

In Arabian Gulf waters of the United Arab Emirates, sailfish (Istiophorus platypterus) are seasonally resident from October through April. Recreational anglers started occasional, self-initiated tagging in 1983. Tags originating from one local and five foreign agencies have been infixed. Early tagging and recovery data was often obscure or lost. In 1997, a concerted effort to understand migration cycles began by consolidating tagging practices and monitoring tag recoveries. Conventional dart tags were infixed on 1871 sailfish from 15 April 1996 to 21 April 2001. Recovered tags (n = 92), as of 16 July 2001, indicated a recapture rate of 4.91%. Of these, 90.21% (n = 83) were recovered during May/June in Iranian waters and represent springtime migratory movement leading north-west, further into the Gulf. Time-at-large for all recaptures ranged from 17 to 1148 days, while point-to-point travel extended from 2.5 to 697 km. Sailfish recaptured in the same year (n = 59) and exhibiting migratory movement travelled a mean distance of 474 km. Location of sailfish during late July through September is unknown, owing to deficiencies in tag recoveries, catch data and anecdotal information. The use of pop-up satellite tags is underway to address this question.

Sailfish (Istiophorus platypterus) is an important apex predator in neritic and oceanic pelagic ecosystems. The species is also a primary target of important catch-and-release sport fisheries that the support local economies of developing countries. However, commercial purse-seine fisheries that target tuna in the eastern Pacific Ocean (EPO) incidentally catch and discard large numbers of sailfish. Sailfish by-catch data recorded by scientific observers in the Mexican tuna purse-seine fleet in the EPO from 1998 to 2007 was used in generalised additive models (GAMs) to predict environmental and spatial preferences of sailfish. GAM predicted the highest sailfish catches to occur in coastal waters during El Niño events during late autumn and winter, with sea surface temperatures >26°C, with negative values of deviation in sea surface height (<–10cm), and low chlorophyll-a (<0.25mgm–3). GAM predicted that the catch probability for sailfish increased 1.8-fold during El Niño events in coastal waters and 1.5-fold under La Niña. However, the spatial distribution of sailfish remained largely unchanged during El Niño and La Niña events. Our models may be an additional fisheries management tool that may be used to support temporary spatial-temporal throughout the fishing season to reduce sailfish by-catch in the EPO.

Pelagic fisheries in the Pacific Ocean target both large (Thunnus spp.) and small tunas (juveniles of Thunnus spp; Katsuwonus pelamis) but also take billfishes (Xiphias gladius, Makaira spp., Tetrapturus spp., Istiophorus platypterus) and sharks (Prionace glauca, Alopias superciliosus, Isurus oxyrinchus, Carcharhinus longimanus, Galeocerdo cuvieri) as bycatch. We developed a multispecies model using the Ecopath with Ecosim software that incorporated time-series estimates of biomass, fishing mortality, and bycatch rates (19521998) to evaluate the relative contributions of fishing and trophic impacts on tuna dynamics in the central Pacific (0°N to 40°N and 130°E to 150°W). The Ecosim model reproduced the observed trends in abundance indices and biomass estimates for most large tunas and billfishes. A decline in predation mortality owing to depletion of large predators was greatest for small yellowfin tuna and could possibly account for apparent increases in biomass. For other tunas, however, predicted changes in predation mortality rates were small (small bigeye) or were overwhelmed by much larger increases in fishing mortality (skipjack and small albacore). Limited evidence of trophic impacts associated with declining apex predator abundance likely results from the difficulties of applying detailed trophic models to open ocean systems in which ecological and fishery data uncertainties are large.

In the waters surrounding Banco Chinchorro in the Mexican Caribbean are spawning and nursery areas for many types of fish. In this natural environment, as opposed to under controlled laboratory conditions, it is almost impossible to link an individual egg to the adult that laid it. This makes identifying the species of the eggs difficult. However, DNA barcodes have made this easier. In the present study, 300 eggs were processed for molecular analysis, from which 139 sequences were obtained. We identified 42 taxa (33 species with their binomial names), 35 genera, and 24 families. The identified eggs included those from Ariomma melanum, which is the first recording of this species in the Mexican Caribbean. Eggs from economically important fish species were also identified, including frigate tuna (Auxis thazard), crevalle jack (Caranx hippos), common dolphinfish (Coryphaena hippurus), sailfish (Istiophorus platypterus), white marlin (Kajikia albida), skipjack tuna (Katsuwonus pelamis), blackfin tuna (Thunnus atlanticus), and swordfish (Xiphias gladius). We have also described new morphological characteristics and captured photographs for 21 species, as well as obtained new information about spawning locality and time for 16 species. This valuable information will provide the basis to develop more effective conservation measures for sustainable fisheries and protection of the Mesoamerican Barrier Reef System.

Ecological risk assessments of the oceanic tuna fisheries on the secondary species in the Sea of Vietnam were conducted following the productivity and susceptibility analysis (PSA) method suggested by Marine Stewardship Council. The secondary species were identified through compilation and analysis of data collected in 67 observer trips conducted on board of commercial tuna fisheries by Research Institute for Marine Fisheries (RIMF) and WWF-Vietnam during the period 2000-2016. The consequence analysis pointed out that there were 12 secondary species of tuna fisheries which were taken into PSA analysis. The results indicated that most of species were at medium and low risk level. Species considered at medium risk are Pelagic thresher (Alopias pelagicus), Blue shark (Prionace glauca), Scalloped hammerhead (Sphyrna lewini), Wahoo (Acanthocybium solandri), Escolar (Lepidocybium flavobrunneum), Indo-Pacific sailfish (Istiophorus platypterus) and at low risk are Longtail tuna (Thunnus tonggol), Swordfish (Xiphias gladius), Snake mackerel (Gempylus serpens), Black marlin (Makaira indica), Indo-Pacific blue marlin (M. mazara) and Common dolphinfish (Coryphaena hippurus). Yellowfin Tuna (Thunnus albacares) and Bigeye Tuna (T. obesus) are target species and both at ecologically low risk level. The results also showed that tuna handline fishery has less impacts on group of secondary species compared to longline fishery.
