To identify differentially expressed genes from channel catfish macrophages, a cDNA library from LPS-stimulated catfish macrophages was screened by subtractive hybridization. This screening yielded a 552-bp cDNA coding for catfish thioredoxin (CF-TRX). The deduced amino acid sequence revealed that CF-TRX contains 107 amino acids and is 59% homologous to human adult T cell leukemia-derived facto...

The present experiments were designed to determine the efficacy of metomidate hydrochloride as an alternative anesthetic with potential cortisol blocking properties for channel catfish Ictalurus punctatus. Channel catfish (75 g) were exposed to concentrations of metomidate ranging from 0.5 to 16 ppm for a period of 60 min. At 16-ppm metomidate, mortality occurred in 65% of the catfish. No morta...

Ferritins are the major iron storage protein in the cytoplasm of cells, responsible for regulating levels of intracellular iron. Ferritin genes are widely distributed in both prokaryotes and eukaryotes. In mammals, ferritin molecules are composed of heavy- (H) and light- (L) chain subunits; amphibian genomes contain three ferritin-type genes (H; middle, M; and L subunits); and teleost genomes t...

Clarias Batrachus merupakan nama ilmiah dari Lele Jawa, atau lele asli, asli perairan Indonesia. Ikan ini mempunyai kebiasaan berjalan di daratan yang bertujuan untuk mencari daerah dengan lebih banyak air, sehingga ikan sering disebut Walking Catfish. Pemubidayaan jawa begantung pada kualitas benih. Hal karena benih berkualitas, adalah salah satu hal menciptakan menghancurkan kesuksesan sebuah...

Abstract Walking catfish Clarias batrachus is a freshwaterr fish that has high economic value. Currently, the culture of this local been initiated in Indonesia, but breeding technology not well developed. Therefore, study aims to explore type natural extender for sperm preservation C. so it can support development its technology, especially remote areas. The research was conducted at Hatchery L...

Edwardsiella ictaluri is a Gram-negative facultative intracellular pathogen causing enteric septicemia of channel catfish (ESC). The disease causes considerable economic losses in the commercial catfish industry in the United States. Although antibiotics are used as feed additive, vaccination is a better alternative for prevention of the disease. Here we report the development and characterizat...

— American White Pelicans ( Pelecanus erythrorhynchos ) are reported to consume large quantities of commercial catfish in Alabama, Arkansas, Louisiana and Mississippi, negatively impacting aquaculture production. If pelicans consume a single item diet, such as catfish, nutritional deficiencies may result. Therefore, effects of monoand multi-species diets were examined to determine nutritional i...

Two experiments were conducted in 200-m earthen ponds at Asian Institute of Technology, Thailand, for 87 days to test the feasibility of an integrated pen-cum-pond system, which utilizes wastes from intensive culture of hybrid catfish (Clarias macrocephalus C. gariepinus) as nutrients for semi-intensive culture of Nile tilapia (Oreochromis niloticus). This integrated pen-cum-pond system enhance...
