The proximal composition, amino acids and fatty acid profile were determined in whole body of wild captive southern hake (Merluccius australis) order to evaluate the differences nutrients content due nutritional quality feed consumed during broodstock conditioning this species. Body composition did not show significant dry matter, protein or ash between both studied groups. Conversely, lipid wa...

Molecular markers can be used to monitor genetic variability in cultivated fish stocks with the aim of developing better aquaculture techniques and increasing productivity. Our objective was evaluate pirarucu broodstocks farms southeast northeast Pará state, Brazil. The samples were genotyped using four microsatellite markers, diversity indices calculated for each broodstock. A total 16 alleles...

some biological characteristics of broodstock and juvenile kutum, rutilus kutum. were investigated using data collected from the estuaries of tajen and shirood rivers (tr and sr) (southern caspian sea basin) as well as from the caspian sea in 2012. the results showed higher condition factors (cf) in the male broodstocks kutum than those estimated in the female broodstock of both tr and sr. the ...

The present study was carried out to investigate the status of health and disease, and their impact on shrimp broodstock (Litopenaeus vannamei) in Khouzestan Province (Choeibde Area) in the south of Iran. From March 2012 until April 2013, about 140 broodstock and 5000 postlarvae (PLs) were collected from hatcheries and grow out farms. Clinical signs of samples were documented in take history fo...

The culture of Octopus vulgaris is constrained by unsolved problems in paralarvae rearing, mainly associated to the unknown nutritional requirements of this species in early stages. In this article we studied the fatty acid profile (total, neutral, and polar lipid fractions) in wild eggs and wild hatchlings, collected in Gran Canaria (SW) (Spain) with artificial dens, in comparison to hatchling...

The Vibrio spp. are the most common and harmful shrimp pathogenic bacteria causing serious diseases of larval and postlarval stages in the hatchery. The Vibrio inhibitory activity of green algae Tetraselmis suecica has been reported in vitro (Austin and Day 1990).In these experiments, the inhibitory activity was assessed in vivo in a commercial shrimp hatchery of the white prawn Fenneropenaeus ...
