Abstract:

Understanding the early life stages of fishes and the processes influencing their survival has been at the heart of the fisheries oceanography since the beginning of the 20th century. By focusing on spatial and temporal patterns in the ichthyoplankton (those early stages whose horizontal location is largely determined by currents), it is possible to gain some understanding of interrelationships among environmental conditions, fish spawning phase and dispersal/survival dynamics of the planktonic stages of fish. The different physical and/or biological processes controlling Larval Fish As

Abstract:

Ichthyoplankton dynamics in the permanently open Kowie Estuary, in the warm temperate region of South Africa was investigated. The composition, abundance, distribution and seasonality of larval fishes were studied over a two year period between 2004 and 2006. Additionally, tidal exchange of ichthyoplankton and the use of frontal zones in the mouth region of the estuary were also explored between 2008 and 2009. Temporal and spatial trends in occurrence of larval fishes within the estuary and associated marina were obtained from data collected seasonally using boat-based plankton netting at 14 s

Abstract:

Many lotic fish species use natural patterns of variation in discharge and water temperature as spawning cues and these natural patterns are often altered by river regulation. The effects of spring discharge and water temperature variation on the spawning of shovelnose sturgeon Scaphirhynchus platorynchus and other fishes in the upper Missouri River have not been well documented. In 2006, 2007, and 2008, I had the unique opportunity to study the effects of experimental discharge levels on ichthyoplankton density in the lower Marias River, a regulated tributary to the upper Missouri River.

The objective of this dissertation was to examine sailfish (Istiophorus platypterus) and blue marlin (Makaira nigricans) spawning in the Straits of Florida, with a specific focus on 1) the physical and biological characteristics of the spawning environment, and 2) the role of the region within the broader spawning patterns of these two species. In order to accomplish these objectives, two years of monthly ichthyoplankton collections and physical measurements across the Straits of Florida were combined with a finer-scale Lagrangian study.

Biophysical dispersal models (BDMs) — a hydrodynamic model coupled with a biological model — lend themselves to inferring potential connectivity patterns, as experimental studies using current methods are inherently difficult over extended spatial and temporal scales. This thesis explored the biological processes that affect the connectivity patterns of ichthyoplankton using four related data chapters. The first data chapter, a meta-analysis of connectivity studies using BDMs, investigated both trends and consequences of modelling choices on derived connectivity patterns. The results of this m

Fish larvae in Australian waters have been studied progressively in the last 2-3 decades including the distribution and abundance of taxa, growth and age, their prey and predators.

My study was aimed to examine the effect of natural or anthropogenic nutrients on the abundance, distribution, growth and condition of fish larvae along-shore of the NSW coast (latitude 30-34S), where the East Australian Current departs the NSW coast and generates local upwelling of cool

Larvae were sampled using replicated oblique bongo net tows along a five-station transect extending from inshore (18m depth) to offshore waters (1000m depth). A total of 148 taxa from 93 teleost families were identified. Larvae of Gobiidae, and Blenniidae were abundant inshore, while larvae of pelagic and reef-dwelling families, such as Clupeidae, Engraulidae, Carangidae and Labridae were common in continental shelf waters.

Abstract:

Artificial reefs (ARs) have been deployed on the inner shelf of Paraná State, south Brazil, to recuperate marine biodiversity and as protection against destructive trawling activities. The purpose of this study was to offer a first characterization of the ichthyoplankton community associated with the ARs and the adjacent archipelago of Currais. Two sampling methodologies were used; 1) plankton net attached to an underwater scooter and; 2) light-traps. A hydrodynamic model was used to study dispersal trajectories to and from the study area. Sampling was conducted between 31.07.14 and 04.04.16.

One of the most sensitive life periods for each species is the first life stages (larval and juvenile). The survival rates of pelagic fish larvae in these phases are usually very low and subject to fluctuations, consequently affecting the recruitment of new generations.

Abstract:

Fish larvae are particularly sensitive to a number of factors and, since larval survival may directly influence future abundances of adult stocks, understanding how larval survival and populational fluctuations affects the yearly recruitment strength and spatial distribution of populations becomes of key importance. The main objectives of this research were to perform a taxonomic characterization of the ichthyoplankton collected along the Cacheu river, assess its biodiversity and how it fluctuates with environmental variability. To achieve this, we performed a taxonomical identification and qu

Indiana University-Purdue University Indianapolis (IUPUI)<br>Recently there has been a lot of effort in developing systems for sampling and automatically classifying plankton from the oceans. Existing methods assume the specimens have already been precisely segmented, or aim at analyzing images containing single specimen (extraction of their features and/or recognition of specimens as single targets in-focus in small images). The resolution in the existing systems is limiting. Our goal is to develop automated, very high resolution image sensing of critically important, yet under-sampled, co

Abstract:

The study and the analysis of marine ecosystems is a significant part of the marine science research. These systems are valuable resources for fisheries, improving water quality and can even be used in drugs production. The investigation of ichthyoplankton inhabiting these ecosystems is also an important research field. Ichthyoplankton are fish in their early stages of life. In this stage, the fish have relatively similar shape and are small in size. The currently used way of identifying them is not optimal. Marine scientists typically study such organisms by sending a team that collects sampl

Abstract:

Estuaries play a key role as nurseries for fish larvae and are critical for the early life stages of fish development. However, these can be highly affected by direct human impacts as well as climate change. Climate variability distresses the ichthyoplankton assemblages with consequences in the marine pelagic food webs and fish populations biology (namely recruitment). This study aims to investigate the influence of environmental variability on interannual abundance of ichthyoplankton assemblages of the Mondego estuary (Portugal), on a long-term scale. For this, an ichthyoplankton samp
