this investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. a total number of 116 catfish (silurus glanis) were collected from zarrine-roud river and examined for helminths. fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope...

There is a strong competition from low-priced imported catfish fillets resulting in a declining market share for domestic farm-raised catfish fillets. To match the competition, catfish processors are embarking on pricing policy measures that are volume-oriented instead of profitor image-oriented. This could be an effective short-run pricing policy measure for optimal longrun sustainability and ...

INTRODUCTION Abscess formation and cellulitis in the setting of envenomation are rare complications of handling catfish. To the best of our knowledge, isolation of Proteus vulgaris has not been previously recorded, and recovery of Morganella morganii has been reported in only one prior case from wound cultures in patients injured by catfish stings. We report a case of catfish envenomation chara...

Catfish is often consumed as a breaded and battered fried product; however, there is increasing interest in breaded and battered baked products as a healthier alternative. Par frying can improve the texture properties of breaded and battered baked products, but there are concerns about the increase in lipid uptake from par frying. The objective of this study was to examine the effect of differe...

Gelatins from the skin of four different species of fresh water fish, namely pangas catfish (Pangasius pangasius), Asian redtail catfish (Hemibagrus nemurus), striped snakehead (Channa Striata), and Nile tilapia (Oreochromis niloticus) have been successfully extracted by citric acid. The gelatin from pangas catfish was found to possessed the highest rheology properties compared to the others. I...

Pollution affects aquatic systems worldwide and there is an urgent need for efficient monitoring. Fish are generally sensitive to their environment and are thus considered to be valuable bioindicator species. The African Sharptooth catfish (Clarias gariepinus) is particularly important in this respect because of its very wide distribution. In order to use C. gariepinus as a bioindicator species...

Bacteriophage Listex P100 (phage P100) was approved by the U.S. Food and Drug Administration and U.S. Department of Agriculture's Food Safety and Inspection Service for Listeria monocytogenes control on both raw and ready-to-eat food products. In this article, we present the proof of concept on the influence of phage dose, phage contact time, and storage temperature on the listericidal activity...

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...

has become common in farmraised channel catfish. It can kill a few dozen fish over several days, or up to 100 percent of the fish in less than 3 days. Recurrence in the same pond is rare. From 1991 to 1995 PGD was the fourth most commonly diagnosed disease of catfish in the southeastern U. S., occurring in one out of every ten disease cases. This disease causes catfish to suffocate because of t...
