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 contribute the development tilapia aquaculture in Côte d’Ivoire by increasing productivity Oreochromis niloticus fry fish hatcheries. Thus, production larvae compared between two breeding systems, earthen ponds and hapas ponds. Over 98 days, 900 broodstock were allowed reproduce 500 m2 others 20 50 m2, each installed 1200 m2. sex ratio one male for females at a dens...

Symbiodinium are responsible for the majority of primary production in coral reefs and found in a mutualistic symbiosis with multiple animal phyla. However, little is known about the molecular signals involved in the establishment of this symbiosis and whether it initiates during host larval development. To address this question, we monitored the expression of a putative symbiosis-specific gene...

  The first time the white spot disease (WSD) and IHHNV were reported in Iran was in 2004 and 2008, respectively in Bushehr Province. In Sistan and Balochestan province only the WSD was reported in 2008.The aim of this study was detecting these two viral diseases in these provinces, during December 2009 to April 2010. A total of 364 samples were collected according to suspected gross signs from...

Recent advances in genotyping-by-sequencing have enabled genome-wide association studies in nonmodel species including those in aquaculture programs. As with other aquaculture species, rainbow trout and steelhead (Oncorhynchus mykiss) are susceptible to disease and outbreaks can lead to significant losses. Fish culturists have therefore been pursuing strategies to prevent losses to common patho...

Proximate analysis of broodstock and grow-out feeds for gamitana (Colossoma macropomum) and paco (Piaractus brachypomus) and their constituent feedstuffs was conducted. Literature values for specific nutrients known to affect fish reproduction were calculated from published sources for the broodstock diet. Fatty acid and amino acid profiles of broodstock eggs were obtained. Analytical informati...

One of the keys for an optimal Eurasian perch aquaculture broodstock management is being able to determine sex individuals. For perch, compared with other methods identification fish and according 3R principle (replacement, reduction refinement), ultrasonography a rapid, non-lethal, non-invasive accurate method. During two successive experiments, we used ultrasound identify gender immature broo...
