Bacterial and fungal pathogens in recirculating aquaculture egg incubation systems can cause elevated mortality decreased production. Peracetic acid (PAA) is a relatively low-cost, safe, effective disinfectant; however, its toxicity to early life stages of the Atlantic salmon (Salmo salar) has not been assessed. The 24-h LC50 value PAA was determined for three salmon: eyed eggs, fry (~0.17 g), ...

  The stocks of Caspian roach ( Rutilus rutilus ), an economically important species in the Caspian Sea, is depleting. Annually, millions of fingerlings of these species are produced artificially and restock in the mouth of Qare Soo River in the Southern Caspian Sea, where they exposed to the pesticides coming from rice and orchard farms in the region. The fate of this exposure in hypo-osm...

The current study was carried out to investigate the effects of dietary supplementation lysine and methionine on growth performance, approximate carcass compositions haematological biochemical parameters in common carp, Cyprinus carpio fingerlings (average weight 22 ± 0.9 g) for 10 weeks. Four experimental diets were prepared with supplemented at levels (0 (control diet), T1 (1Lys 0.4Met g/kg),...

The objectives of the present study were to evaluate potential Korill (KO), a product based on krill oil, supplemented in fish feed (5 g/kg feed) alleviate density-induced stress carp fingerlings, and its protective capacity case anthelmintic drug administration (ABZ—albendazole). Thus, divided into four groups: LD (low density with normal feed), LD-KO KO supplementation HD (high HD-KO feed). D...

To understand the welfare implication of photoperiod manipulation on Clarias gariepinus, fingerlings (n = 108) and juveniles C. gariepinus with a mean weight 3.75±0.03 g 21.7±2.88 were exposed to zero light (0L:24D)-T1, average (12L:12D)-T2 continuous (24L:0D)-T3 in triplicates for 35 days. The highest mortality rate was recorded T2 T3 (13.9%) (22.2%). T1 significantly higher (p 0.03) weekly gr...

This study aimed to identify the effect of stocking density on growth, feed efficiency, and survival during transition from Peruvian grunts (Anisotremus scapularis) fingerlings juveniles. Fingerlings were reared in triplicate for 63 days until reaching juvenile stage, at 1000 fingerling·m−3 (low-density LSD, 0.79 kg·m−3), 2000 fingerlings·m−3 (medium-density MSD, 1.58 3000 (high-density HSD, 2....

a study was carried out to evaluate the probiotic activity of bacillus subtilis g1 isolated from fermented pickles in growth performance and disease resistance of hemibagrus nemurus fingerlings at universiti putra malaysia. the probiotic was mixed in feed at doses of 0 (c, control), 3 x 109 (t1) 3 x 107 (t2) and 3 x 105 (t3) cfu g-1 and fed to the catfish fingerlings for nine weeks. results sho...
