Three hundred and six fish of 83 species were carefully examined in Kuwait during the period from October 1992 to September 1995 for ascaridoid larvae. Thirty-nine fishes (12.7%) belonging to 23 species were infected with 9 types of ascaridoid third-stage larvae: Anisakis simplex, Terranva spp, Contracaecum spp and 6 different types of Hysterothylacium spp (KA-KF). Hysterothylacium larvae (incl...

Between August 2000 and August 2001, 12,216 fish of 73 species were purchased from several local markets in Nakhon Nayok Province, Thailand, and examined for the presence of Gnathostoma larvae. Almost all species were fresh-water fish that had grown naturally, rather than raised commercially. Eight species were found to be infected with gnathostome larvae. The overall prevalence was 5.1% (626/1...

The present work deals with the study of fish larvae of coral reef fishes in the Red Sea (Hurghada). It was aimed to study the spatial and temporal variations of fish larvae for management purposes. Sampling stations were chosen at Marina, Sheraton, Magawish and Arabia. The samples were taken monthly throughout the period of the study from August 2014 to July 2015 using plankton nets of differe...

Questions: Do larvae of a dragonfly with a broad habitat distribution have longer abdominal spines when they co-exist with fish, and are these differences the result of phenotypic plasticity? Hypothesis: Phenotypic plasticity will result in larvae having longer spines when they are exposed to cues from predatory fish. Organism: Larvae of Leucorrhinia intacta (Odonata: Libellulidae). Research si...

The annual cycles of abundance of fish larvae and their zooplankton prey were analysed in relation to the biomass and production of size-fractionated phytoplankton on the Scotian Shelf (North-west Atlantic). Outside the spring bloom of large (>5 ìm) phytoplankton (February to April), the small-sized fraction of phytoplankton (<5 ìm) contributed the bulk of total primary production. The producti...

It is a common problem in ecosystem studies that information about predation on fish larvae is extremely sparse. There is little information about agents of mortality. This is likely to be because fish larvae are digested very rapidly in a predator’s stomach. This study describes controlled experiments designed to evaluate the potential role of small low-trophic level fishes as predators on pel...

  To determine the best live food and to reevaluate the optimal weaning period for beluga fish (Huso huso) larvae, seven experimental diets: Daphina (DP), Chironomids (CH), Gammarid (G), Daphina + formulated diet (DPFD), Chironomids + formulated diet (CHFD), Gammarid + formulated diet (GFD ) and formulated diet (FD ) in triplicate groups were fed to 4662 sixteen-days-old larvae which were captu...
