The fisheries of the lower reaches Tigris river, north Qurna in Basrah Governorate have been analyzed during period from January to December 2005. fishing boats used there varied lengths form 5 10m, which 50% were motorized with 25-75 HP. Seine and drift gill nets are main gears used, their ranged 100 200m mesh sizes 14-100mm 7-32mm for seine respectively. number fishermen each boat 1 7. Twenty...

One grotesque catfish specimen was collected in Zhangjiang River (upper reach of a secondary tributary of Hongshuihe River) in Libo County, Guizhou Province, China. This specimen bears surprising character of four dorsal fins, which have not appeared in any other silurid fishes. But other morphological characters, such as two pairs of barbels, lower jaw projecting beyond upper jaw, the first do...

The primary structure of catfish (Silurus asotus) egg lectin (SAL) was determined. SAL cDNA contained 1448-bp nucleotides and 308 amino acid residues, deduced from open reading frame. The SAL mature protein composed of 285-amino acid residues was followed by a predicted signal sequence having 23 residues. The mRNA of SAL was found to be expressed in eggs, but not in liver. SAL is composed of th...

The present experiment was conducted to evaluate the efficacy of dietary fermented by-product of mushroom, Pleurotus ostreatus, (FBPM) as a fish meal (FM) replacer in juvenile Amur catfish, Silurus asotus. A total number of 225 fish averaging 5.7±0.1 g (mean±standard deviation) were fed one of the five experimental diets formulated to replace FM with FBPM at 0%, 5%, 10%, 20%, and 30% (FBPM0, FB...
