Many marine fish harbor luminous bacteria as bioluminescent symbionts. Despite the diversity, abundance, and ecological importance of these fish and their apparent dependence on luminous bacteria for survival and reproduction, little is known about developmental and microbiological events surrounding the inception of their symbioses. To gain insight on these issues, we examined wild-caught larv...

In this study the effect of different protein levels on reproductive performance of Channa striatus was conducted. Snakehead juveniles (65.5±0.2 g) were randomly distributed into nine homogenous groups of 75 fish each. Three isocaloric experimental diets differing in protein levels were prepared. The experiment lasted for 8 months and gonadosomatic index, absolute fecundity, egg diameter, numbe...

The reproduction and early growth of fish are essential elements that affect recruitment provide breakthrough points for understanding population fluctuations. In this study, larval juvenile Japanese anchovy (Engraulis japonicus) were collected from five coastal waters off the Pacific coast Japan in 2020 2021 to gain more insight into life history traits such as species on basis otolith microst...

The negative effects of large larval concentration on larval development have been reported for many marine planktotrophic invertebrates. Comparable data for the lecithotrophic species are, however, not available. The present study was therefore undertaken to determine the influence of varying larval concentrations on the developmental performance of Babylonia formosae (Sowerby). The larvae of ...

In total 17 families comprising more than 29 species of larval teleost fishes were recorded in the Kromme Estuary during the study period. Dominant species included Atherina breviceps, Caffrogobius gilchristi, Diplodus sargus capensis, Gilchristella aestuaria, Glossogobius callidus, Rhabdosargus holubi and Rhabdosargus globiceps. The larval fish catch in the estuary indicated a marine dominance...

The objective of this study was to investigate influence meso-scale eddies in the western South China Sea on species composition and spatial patterns fish larvae juveniles based data collected during summer autumn 2012. Nintyeight belonging 38 families were collected, including 78 41 autumn. dominant Vinciguerria sp. (39.70%), Stephanolepis cirrhifer (11.21%), Caranx (5.45%) Benthosema pterotum...

Feeding success is essential to larval fish survival. We present detailed mechanistic models of the foraging processes (prey encounter, approach, pursuit, and capture) in larval fish, where all parameters have explicit physical or biological meaning. The model is a unification of the processes believed to be important to prey selectivity and environmental regulation of feeding in fish. We inclu...

—We analyzed data on spring and summertime larval and juvenile fish distribution and abundance in the upper San Francisco Estuary (SFE), California between 1995 and 2001. The upper SFE includes the tidal freshwater areas of the Sacramento–San Joaquin Delta downstream to the euryhaline environment of San Pablo Bay. The sampling period included years with a variety of outflow conditions. Fifty ta...

Two methods were developed for the production of larval fish diets. The first method, microextrusion marumerization (MEM), has been tested in laboratory feeding trials for many years and produces particles that are palatable and water stable. The second method, particle-assisted rotational agglomeration (PARA), produced diets that have lower density than diets produced by MEM. Each method was u...
