Lates calcarifer fish

This study was carried out to evaluate effects of loading density during transport on water quality and survival rate of Asian seabass (Lates calcarifer) juvenile. The experiment included four treatments of different loading densities: 50 kg/m3 (T1), 70 kg/m3 (T2), 90 kg/m3 (T3) and 110 kg/m3 (T4) with three replicates for each treatment. The fish with an average weight of 20.50 ± 0.25 g was transported in an aerated and oxygenated heat-insulated tanks.

The results of the Ca/P molar ratio from 1.839 to 1.847 prove that the nano-HAp powders are B-type biological hydroxyapatites, which has been confirmed by FTIR spectrum. In addition, the content of heavy metals such as As, Pb, Hg, Cd is detected within safety limits. These properties allow nano-HAp powders to be applied in food and medicine fields.

Neobenedenia girellae is one of the most pathogenic parasites affecting marine fish in captivity conditions. The use of chemicals for parasite prevention and treatment have several benefits; however, they can cause various negative side-effects. In an effort to discover cost-effective and sustainable practices, our current study was aimed at investigating the efficiency of freshwater treatments on N. girellae. A challenge test was conducted to produce infected fish which became materials for the freshwater immersion experiments.

This study was conducted to study the effect of stocking density on growth and survival of seabass, Lates calcarifer in floating net cages in closed bay, Bapatla, Andhra Pardesh, India. Triplicate groups of seabass with an average initial weight of 1.29±0.12 g were randomly stocked in floating net cages (1m×1m×2m) at 20, 40, 60 and 80 fish/m3designated as SD20, SD40, SD60 and SD80 respectively. Seabass in the cages were fed with 45% CP formulated diet at 10% of body weight twice daily. Sampling was done weekly.

Gần đây phát triển nghề nuôi cá biển ở các vùng nước ven biển của Việt Nam đòi hỏi chất lượng giống thả. Do đó, nỗ lực to lớn, được đầu tư Thiết lập nối kết trong sản xuất sản xuất giống cho các loài nuôi Một số phổ biến, như vậy như cá chẽm châu Á (Lates calcarifer), cá mú (Epinephelus spp.) và cá giò (Rachycentron canadum). Trong khi một số lượng đáng kể của giống đã được sản xuất bởi các Hatchery địa phương, cá vẫn còn quá nhỏ để thả nuôi ao, net lồng....
