The early life stages of marine fishes play a critical role in population dynamics, largely due to their high abundance, high mortality, and ease of transport in ocean currents. This dissertation demonstrates the value of combining larval data, collected in the field and the laboratory, with model simulations. In Chapter 2, analyses of field observations of ontogenetic vertical distributions of coral reef fish revealed a diversity of behaviors both between and within families. In Caribbean-wide particle-tracking simulations of representative behaviors, surface-dwelling larvae were generally transported longer distances with greater population connectivity amongst habitat patches, while the evenly-distributed vertical behavior and downward ontogenetic vertical migration were similar to one another and led to greater retention near natal sites. However, hydrodynamics and habitat availability created some local patterns that contradicted the overall expectation.
Chapter 3 presents evidence of tuna spawning inside a large no-take marine protected area, the Phoenix Islands Protected Area (PIPA). Despite variation in temperature and chlorophyll, the larval tuna distributions were similar amongst years, with skipjack (Katsuwonus pelamis) and Thunnus spp. tunas observed in all three years. Backtracking simulations indicated that spawning occurred inside PIPA in all 3 study years, demonstrating that PIPA is protecting viable tuna spawning habitat. In Chapter 4, several lines of larval evidence support the classification of the Slope Sea as a major spawning ground for Atlantic bluefin tuna with conditions suitable for larval growth. The abundance of bluefin tuna larvae observed in the Slope Sea aligns with typical observations on the other two spawning grounds.
Age and growth analyses of bluefin tuna larvae collected in the Slope Sea and the Gulf of Mexico in 2016 did not show a growth rate difference between regions, but did suggest that Slope Sea larvae are larger at the onset of exogenous feeding. Collected larvae were backtracked to locations north of Cape Hatteras and forward tracked to show that they would have been retained within the Slope Sea until the onset of swimming. As a whole, this thesis presents valuable contributions to the study of larval fishes and the attendant implications for marine resource management.

Texto completoThis study aimed to evaluate the effect of the supply of microalgae Chaetoceros muelleri and Thalassiosira fluviatilis on growth, survival and larval development time of the sea cucumber Holothuria grisea. Holothuria grisea larvae were obtained from a spawning induced by heat shock and were cultured in incubators conical cylinder with volume of 15 L, kept in a density of 0,5 larvae/ml and constant aeration. The temperature, pH, dissolved oxygen and water salinity were measured daily and total ammonia analysis (NH3 / NH4+) and nitrite (NO2-) were done on days 05, 09 and 14 after fertilization. Four treatments were tested with five replicates each: a diet with 100% Chaetoceros muelleri; a diet with 100% Thalassiosira fluviatilis; a combined diet containing 50% Chaetoceros muelleri and 50% Thalassiosira fluviatilis (mixed diet); and control (unfed). The feed rate ranged from 20.000 the 40.000 cells/ml for different stages of development. The length of the larvae (μm) was observed on days 2, 8 and 14 after fertilization and survival (%) on days 4, 10 and 14 after fertilization. The larval development time was followed for all treatments. There was no significant difference in temperature, pH, dissolved oxygen and salinity, to the different treatments tested. The best treatments in terms of water quality were Chaetoceros muelleri and Control, with the lowest concentrations of total ammonia and nitrite. The highest concentrations of ammonia and nitrite were found in treatments where the microalgae Thalassiosira fluviatilis was present. The survival rate for all treatments decreased over larval development being quite sharp. The best treatment, when considering the larval development time and total length (μm), was Chaetoceros muelleri. Holothuria grisea completed it larval development time in 17 days after fertilization when fed Chaetoceros muelleri, having indirect development with larval stages of auricularia, doliolaria and pentacula until the arrival of the juvenile stage.
A presente pesquisa teve como objetivos avaliar o efeito da oferta das microalgas Chaetoceros muelleri e Thalassiosira fluviatilis sobre o crescimento, a sobrevivÃncia e o tempo de desenvolvimento larval do pepino do mar Holothuria grisea. As larvas de Holothuria grisea foram obtidas a partir de uma desova induzida por choque tÃrmico e foram cultivadas em incubadoras cilindro cÃnicas, com volume Ãtil de 15 L, mantidas sob uma densidade de 0,5 larvas/mL e aeraÃÃo constante. A temperatura, o pH, o oxigÃnio dissolvido e a salinidade da Ãgua foram mensurados diariamente e anÃlises de amÃnia total (NH3/NH4+) e nitrito (NO2-) foram feitas nos dias 05, 09 e 14 apÃs a fertilizaÃÃo. Foram testados quatro tratamentos com cinco repetiÃÃes cada: uma dieta com 100% de Chaetoceros muelleri; uma dieta com 100% de Thalassiosira fluviatilis; uma dieta combinada contendo 50% de Chaetoceros muelleri e 50% de Thalassiosira fluviatilis (dieta mista); e o controle (sem alimentaÃÃo). A taxa de alimentaÃÃo variou de 20.000 a 40.000 cÃlulas/mL para os diferentes estÃgios de desenvolvimento. O comprimento das larvas (μm) foi verificado nos dias 2, 8 e 14 apÃs a fertilizaÃÃo e a sobrevivÃncia (%) nos dias 4, 10 e 14 apÃs a fertilizaÃÃo. O tempo de desenvolvimento larval foi acompanhado para todos os tratamentos testados. NÃo houve diferenÃa significativa nos valores de temperatura, pH, oxigÃnio dissolvido e salinidade, para os diferentes tratamentos testados. Os melhores tratamentos em termos de qualidade da Ãgua foram Chaetoceros muelleri e Controle, apresentando as menores concentraÃÃes de amÃnia total e nitrito. Maiores concentraÃÃes de amÃnia e nitrito foram verificadas nos tratamentos em que a microlaga Thalassiosira fluviatilis estava presente. A taxa de sobrevivÃncia para todos os tratamentos testados diminuiu ao longo do desenvolvimento das larvas sendo bastante acentuada. O melhor tratamento, quando considerado o tempo de desenvolvimento larval e o comprimento total (μm), foi Chaetoceros muelleri. Holothuria grisea completou o seu tempo de desenvolvimento larval em 17 dias apÃs a fertilizaÃÃo quando alimentadas com Chaetoceros muelleri, tendo desenvolvimento indireto com fases larvais de auriculÃria, doliolÃria e pentÃcula atà a chegada da fase juvenil.
Wheeler, Sarah Grace. "Biological and oceanographic drivers of larval growth, settlement, and recruitment of rockfishes (Sebastes spp.)". Thesis, University of California, Davis, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=3723751.
Texto completoRecruitment of marine fishes is largely determined by biological and oceanographic factors acting on early life stages. Coastal upwelling has long been recognized as a critical factor influencing the survival of larvae and recruitment to adult populations. Dynamics in regional upwelling influence the magnitude and timing of primary productivity, affecting the availability of critical food sources for larval fish. In addition, upwelling-relaxation cycles affect the dispersal of marine larvae and their onshore delivery prior to settlement. Challenges with tracking larvae, however, have limited our understanding of how oceanography influences the early life stages of fishes. The objective of this dissertation is to evaluate the biological and oceanographic drivers of larval growth, settlement, and recruitment, using rockfishes ( Sebastes spp.) as model organisms.
Overlap of larval production and favorable feeding conditions may drive recruitment for many temperate marine fishes, as small changes in larval growth can result in order-of-magnitude differences in year-class-strength. In Chapter 1, I assess the influence of regional productivity, temperature, and larval condition in explaining growth in rockfishes. I employ a combination of otolith microstructure and satellite imagery to measure initial larval growth and estimate the productivity and temperature experienced by individuals to determine their relative importance in subsequent growth at metamorphosis. I compare model performance using indexed environmental conditions scaled over three different regions. In both years of study, net primary productivity explained the most variation in pre-metamorphic growth relative to temperature and initial growth. This relationship was consistent across spatial regions. Recent settlement, juvenile recruitment, and individual growth were significantly higher in a year when productivity bloomed earlier and individual larvae experienced higher levels of productivity. These results support the hypothesis that large-scale oceanographic processes that stimulate upwelling and secondary production are primary drivers of larval growth and subsequent year-class strength in rockfishes.
Characterizing the behavior of larvae prior to settlement is integral to understanding population dynamics because coastal oceanography may facilitate or limit settlement. Otolith microchemistry can be used to determine patterns of fish movement, although there is a limited understanding of how this tool can be applied in coastal marine systems. My goal in Chapter 2 is to evaluate the application of otolith microchemistry to characterize water mass associations of settlement-stage marine fish in a coastal upwelling region using a three-step approach. First, I characterize seawater chemistry of coastal water masses across multiple years, finding significant differences in the chemical signatures of strong upwelling, weak upwelling, and relaxation. Second, I experimentally determine the effect of temperature on the partitioning of trace elements in otoliths for two rockfishes to find that the effect of temperature on otolith partition coefficients was element- and species-specific. Finally, I compare the synchrony in seawater and otolith chemistry of settlement-stage rockfishes that were exposed to naturally variable conditions over an upwelling-relaxation cycle. I subsequently evaluate whether laser ablation inductively coupled plasma mass spectrometry effectively measures otolith chemistry over ecologically relevant time scales. I discovered that elemental concentrations in otoliths respond rapidly to changes in seawater chemistry and reflect equivalent proportional changes. This study provides evidence that elemental signatures are valuable tools for reconstructing larval histories of marine fish.
In Chapter 3, I use otolith chemistry to examine water mass associations of two juvenile rockfishes during onshore transport and settlement in an upwelling region. I develop a chemical proxy for upwelling and relaxation by characterizing Sr/Ca and Ba/Ca signatures of otoliths collected during these oceanographic conditions. Otolith chemistry differed between rockfishes collected during upwelling and relaxation, with signatures unique to each year. I subsequently compare otolith signatures of rockfishes collected during high and low settlement periods to determine whether specific water masses affect settlement. I provide evidence that copper rockfish associate with upwelling currents during periods of high settlement, suggesting that upwelling may facilitate settlement for these species. Conversely, I found evidence that the closely related gopher rockfish associate with relaxation events during peak settlement periods. This research takes an important first step at in evaluating the utility of trace element signatures to characterize larval fish movement during onshore delivery and settlement in marine systems. Together, these studies improve our understanding of how coastal upwelling impacts larval growth, settlement, and recruitment, which provides important information for understanding population dynamics in marine ecosystems.

Assim sendo, o presente estudo teve como objetivo conhecer a assembleia e a microdistribuição dos camarões Alpheidae presentes na região intermareal estuarina de Cananéia, São Paulo, Brasil. Além de caracterizar a história de vida de Alpheus brasileiro, espécie mais abundante nas áreas estudadas, a estrutura populacional, os parâmetros de crescimento, a longevidade e o desenvolvimento dos primeiros estágios larvais da espécie. As hipóteses de que as espécies apresentam microdistribuição diferenciada na região intermareal e de que a monogamia social influencia na estrutura populacional e nos parâmetros de crescimento de A. brasileiro foram testadas. A região estuarina de Cananéia é considerada uma das mais conservadas da costa brasileira, portanto, todo o conhecimento sobre esse importante ecossistema é fundamental, principalmente para comparações com áreas diferentes graus de conservação.

Abstract: Studies about biodiversity are fundamental for biological knowledge. Therefore, the aim of the present study was to know the assemblage and the microdistribution of the Alpheidae shrimps present in the intertidal estuarine region of Cananéia, São Paulo State, Brazil. In addition to characterizing the life history of Alpheus brasileiro, the most abundant species in the studied areas. Population structure, growth parameters, longevity and development of the first larval stages of the species was also investigated. The hypotheses that the species show differentiated microdistribution in the intertidal region and that social monogamy influences the population structure and growth patterns of A. brasileiro were tested. The estuarine region of Cananéia is considered one of the most conserved of the Brazilian coast, therefore, all the knowledge about this important ecosystem is fundamental mainly for comparisons with areas in different degrees of conservation. The Alpheidae assemblage was characterized by seven species: A. brasileiro, Alpheus buckupi, Alpheus carlae, Alpheus estuariensis, Alpheus petronioi, Athanas nitescens e Salmoneus carvachoi. The microdistribution evidenced the influence of A. brasileiro on the other species, mainly due to the abundance and constancy that this species presented. The results on the population structure of the species are directly related to its monogamous social behavior, in which it is characterized by the formation of heterosexual pairs that s...

Coastal and estuarine environments experience large variability and rapid shifts in pCO₂ levels. Elevated pCO², or ocean acidification, often negatively affects early life stages of calcifying marine invertebrates, including bivalves, but it is unclear which developmental stage is most sensitive. I hypothesized that initial calcification is a critical stage during which high pCO₂ exposure has severe effects on larval growth and development of bay scallop (Argopecten irradians). Using five experiments varying the timing of exposure of embryonic and larval bay scallops to high CO₂, this thesis identifies two distinct stages of development during which exposure to high CO₂/low pH causes different effects on bay scallop larvae. I show that any exposure to high CO₂ consistently reduces survival of bay scallop larvae. I also show that high CO₂ exposure during initial calcification (12-24 h post-fertilization) results in significantly smaller shells, relative to ambient conditions, and this size decrease persists through the first week of development. High CO₂ exposure at 2-12 h post-fertilization (pre-calcification), does not impact shell size, suggesting that the CO₂ impact on size is a consequence of water chemistry during calcification. However, high CO₂ exposure prior to shell formation (2-12 h post-fertilization) causes a high incidence of larval shell deformity, regardless of CO₂ conditions during initial calcification. This impact does not occur in response to high CO₂ exposure after the 2-12 h period. The observations of two critical stages in early development has implications for both field and hatchery populations. If field populations were able to time their spawning to occur during the night, larvae would undergo initial calcification during the daytime, when CO₂ conditions are more favorable, resulting in larger veliger larvae. Hatcheries could invest minimal resources to monitor and modify water chemistry only during the first day of development to ensure larva are exposed to favorable conditions during that critical period.

This study describes the development and allometric growth patterns of larval Piaractus mesopotamicus from induced reproduction. From hatching until the 19th day, twenty individuals were selected for eight stage of development (yolk sac larval, preflexion, initial of flexion, flexion, end of flexion and post flexion). Later, morphometric measurements were taken of each individual: total length, head length, trunk length, tail (post anal) length, head height, body height, muscle height at anus leveleye diameter, mouth length, caudal peduncle height and caudal peduncle length. Allometric growth coefficients were calculated by linear regression; the changes in the coefficients of growth relate to ontogenetic changes in the priorities of the larvae. During the developmental stages of larval yolk and pre-flexion (mean CT = 3.363 and 5.89 mm), the larvae showed an evident priority for feeding and swimming capabilities. From the flexion stage (mean CT = 9.33 mm) was observed a change in growth priorities, especially those relating to body height, important characteristic for this species. From the post-flexing stage (mean CT = 16.25 mm) a greater propensity to isometry was evident for all coefficients growths. These results confirm the informations that there are different growth patterns for priority functions during ontogeny initial larvae. This study of morphometric and allometric growth of larvae Piaractus mesopotamicus, may assist the fisheries biology, supporting management strategies and conservation of natural populations
Este estudo descreveu o desenvolvimento e os padrões de crescimento alométrico de larvas de Piaractus mesopotamicus provenientes de reprodução induzida. Desde a eclosão até o 19° dia, vinte indivíduos foram selecionados para oito estágios de desenvolvimento (larval vitelino, pré-flexão, início de flexão, flexão, final de flexão, início de pós-flexão, pós flexão e final de pós-flexão). Posteriormente, foram tomadas medidas morfométricas: comprimento da cabeça, comprimento do tronco, comprimento da cauda anal posterior, altura da cabeça, altura do corpo, altura do músculo em nível do ânus, diâmetro do olho, comprimento da boca, altura do pedúnculo caudal e comprimento do pedúnculo caudal. Os coeficientes de crescimento alométrico foram calculados por meio de regressões lineares; as alterações ocorridas nos coeficientes de crescimento referem-se as mudanças nas prioridades ontogenéticas das larvas. Durante os estágios de desenvolvimento de larval vitelino e pré-flexão (média CT= 3,36 e 5,89 mm) as larvas apresentaram uma evidente prioridade para as capacidades de alimentação e natação. A partir do estágio de flexão (média CT= 9,33 mm) foi observada uma mudança nas prioridades de crescimento, principalmente as relacionadas com a altura do corpo, característica importante para essa espécie. No estágio de pós-flexão (média CT=16,25 mm) uma propensão maior a isometria ficou evidente, para todos os coeficientes de crescimentos. Esses resultados confirmam as informações de que existem padrões diferenciados de crescimento para funções prioritárias durante a ontogenia inicial de larvas. Este estudo sobre morfometria e crescimento alométrico das larvas de Piaractus mesopotamicus, poderá auxiliar a biologia pesqueira, subsidiando as estratégias de manejo e conservação das populações naturais
