Effects of Artemia urmiana enriched with ICES30/4 as a commercial emulsion of highly unsaturated fatty acid (HUFA) on growth, survival, salinity tolerance and fatty acid composition of the Persian sturgeon larvae were evaluated. Artemia enriched for two different time periods (12 and 24 hours) and non-enriched artemia were fed to A. persicus larvae (average initial wet weight 46.80± 2.03mg) dur...

BACKGROUNDS: Optimization of microbial compositions and load in live food during the process of bioencapsulation is one of the most important concerns in aquaculture, as it can promote the growth and feeding parameters of fish larvae. OBJECTIVES: The aim of this study was to determine the growth and feeding performance of Persian sturgeon larvae fed with bioencapsulated D. magna with Saccharomy...

The study and research of abundance and diversity variation of fish larva (Ichthyoplankton stages) was done in Gowatr Bay during autumn 2006 - summer 2007. Five stations were selected for sampling, and Bongo-Net with 300µ mesh size was towing from bottom to surface. During of survey, totally 531 larvae belong to 11 families were collected and identified. The mean abundance estimated 12.17 larva...

study was undertaken to establish the optimum dietary indispensable amino acid (IAA) profile for yellow fin seabream broodstock based on the amino acid (AA) profile of broodstock, eggs and larvae of Acanthopagrus latus. Three isonitrogenous (40%) and isolipid (20%), named diets 1, 2 and 3 were formulated with different ratios of total essential amino acids per total non-essential amino acid...

the aim of this study was to determine the inhibitory effects of feed ingredients on protease activities of argyrosomus regius larvae using in vitro techniques. a. regius larvae fed on a commercial feeding procedure were sampled thirteen times, during the sampling period (from 3 to 32 days after hatching (dah)). the differences observed in protease activities of meagre larvae during the samplin...

BACKGROUND & OBJECTIVES An efficient larvivorous fish must show a predilection for mosquito larvae in the presence of alternative preys. This study compares the feeding capacity and preference of Aphyosemion gularis exposed to different kinds of aquatic macroinvertebrates. METHODS Various prey organisms such as Anopheles larvae and pupae, Culex larvae, chironomid larvae and ostracods were eit...

 Post larvae of wild and cultured spawners of the Indian white shrimp (Penaeus indicus, Milne Edwards, 1837) were reared to market size, in commercial ponds of shrimp farming site of Helleh, in Bushehr Province, during a six months period. Environmental factors, management process and the diet used to feed shrimps were almost similar for both treatments. Averages of the weight, length, specific...

 Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...

Some marine invertebrate larvae expand the range of settlement cues to which they will respond as they age. How do relatively simple larvae achieve such complex changes in behaviour? Larvae of the Australian sea urchin Holopneustes purpurascens settle and metamorphose specifically in response to a settlement cue, dissolved histamine, produced by the host alga Delisea pulchra. Older H. purpurasc...
