Growth, hematology, and histopathology of channel catfish, Ictalurus punctatus, fed toxins from Fusarium moniliforme

Crescimento e alterações no fígado e na carcaça de alevinos de jundiá alimentados com dietas com aflatoxinas

“…Em estudos realizados com bagre-de-canal, em que os peixes foram intoxicados com níveis altos de fumonisinas, observou-se mortalidade somente a partir de 320 ppm kg -1 (Lumlertdacha et al, 1995). A partir desse nível, ocorreu mortalidade de até 70%, e os peixes sobreviventes estavam muito debilitados.…”

Criteria for Safe Use of Plant Ingredients in Diets for Aquacultured Fish

“…The knowledge of the toxic effects and toxicokinetics of mycotoxins in fish is limited, and studies of dietary exposure to mycotoxins are scarce. In channel catfish exposed to graded levels of dietary fumonisin B 1 (FB 1 ;0,3,20,80,320 and 720 mg/kg feed) for 10 weeks, high mortality (70%) was observed in the two highest exposure groups, with the first mortalities occurring after 2 weeks of exposure (Lumlertdacha et al, 1995). Hepatic histological changes were seen in channel catfish exposed to 20 or more mg FB 1 /kg feed, and the occurrence and severity of the Norwegian Scientific Committee for Food Safety Vitenskapskomiteen for mattrygghet (VKM) 93 07/604 -final changes appeared to be dose-dependent (Lumlertdacha et al, 1995).…”

Indications of liver damage have been seen in carp (Pepeljnjak et al, 2002), while no hepatic lesions were found in Nile tilapia after dietary exposure to fumonisin B 1 (Tuan et al, 2003).…”

Ultra-structural and histochemical analysis of channel catfish (Ictalurus punctatus) liver treated with fumonisin B1

“…Carps (Cyprinus carpio L.), when treated with FB 1 , presented pathological alterations in the parenchymal organs such as the liver, intestines, heart and kidney (Pepeljnjak et al, 2000). In a study carried out in catfish (Ictalurus punctatus) treated with corn feed contaminated with F. verticillioides (20 mg FB 1 /kg), hepatic lesions and inhibition of fish development was observed (Lumlertdacha et al, 1995). Liver glycogen elevation, vacuolization increase in nervous fibers and brain perivascular linphohystiocitic invasion were observed in catfish treated with F. verticillioides culture containing 40 FB 1 /kg .…”
