How do growth and survival of larval fish depend on the availability of zooplankton prey? This question connects plankton ecology to fisheries science and is typically answered by the classical ‘match/mismatch’ hypothesis for explaining recruitment variability to fish populations. In field and experimental data, however, the effects of food abundance on growth are not always unequivocal. Here, ...

Here we describe an efficient and effective technique for rearing sexually-derived coral propagules from spawning through larval settlement and symbiont uptake with minimal impact on natural coral populations. We sought to maximize larval survival while minimizing expense and daily husbandry maintenance by experimentally determining optimized conditions and protocols for gamete fertilization, l...

Horizontal and temporal variations in abundance and productivity of phytoand zooplankton were studied in a frontal area in the NW North Sea during September and October 1985. In addition, distributions of several cohorts of herring larvae found in this area were monitored and larval growth and survival estimated. Phytoplankton biomass and productivity as well as copepod productivity peaked in t...

Our overall goal was to investigate several aspects of pecan weevil, Curculio caryae, suppression with entomopathogenic nematodes. Specifically, our objectives were to: 1) determine optimum moisture levels for larval suppression, 2) determine suppression of adult C. caryae under field conditions, and 3) measure the effects of a surfactant on nematode efficacy. In the laboratory, virulence of He...

In an experimental laboratory investigation on an estuarine crab, Chasmagnathus granulata Dana, we investigated how salinities experienced during embryonic and larval development (embryonic and larval salinity exposures, respectively) and intraspecific variability of initial biomass at egg laying and hatching affected larval performance. The latter was measured in terms of survival rate, durati...

Introduction: Density is one of the critical factors in echinoderm larvae for aquaculture purposes. Echinoplutei are very sensitive to overcrowding. High culture density can lead problems with bacteria or protozoa, decreasing survival and generating abnormal morphotypes. Objective: To evaluate effect on larval growth sea urchin Arbacia dufresnii. Methods: Two days after fertilization A. dufresn...

To compare the reproductive performance of the wild and cultured stocks of beluga, Huso huso males, some spermatological parameters were measured including: sperm motility, sperm density, spermatocrit and also fertilization rate, hatching rate and larval growth and survival rates. The semen samples were sampled from 11 wild spawners and 12 cultured brooders. A half of each semen sample was allo...

The survival, behavior and competence period of lecithotrophic larvae depends not only on the energy allocation transferred by maternal colonies but also amount consumed to sustain embryonic, larval, post-larval development. objective present work is understand effect consumption performance larvae. To this aim, we analyzed free fatty acid (FFA) content composition three Mediterranean octocoral...

Temperature controls the rate of fundamental biochemical processes and thereby regulates organismal attributes including development rate and survival. The increase in metabolic rate with temperature explains substantial among-species variation in life-history traits, population dynamics, and ecosystem processes. Temperature can also cause variability in metabolic rate within species. Here, we ...
