The record is confirmed of a “Clariobranchus” hybrid Clarias gariepinus × Heterobranchus sp. specimen in the River Danube Croatia. was introduced to Europe for farming and research purposes. Because their faster growth short time achieve market size, hybrids have gained attention European aquaculture. To date, no has been found literature escapees inland waters Europe. present finding suggests ...

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...

Nowadays there is a general demand for green chemistry to keep our environment. Chlorophyllin widely used as promising natural pesticide instead of chemical one, which raises the concern studying its eco-toxicological effect on surrounding In this study, both silver and graphene oxide nano-materials were grafted by porphyrin-based chlorophyllin produce four novel nano-pesticides (Mg-Chl/Ag, Mg-...

Reproductive morphometry of Clarias gariepinus (C. gariepinus) is essential in distinguishing different species that are closely related to it and adequate information required regarding the seasonal variation milt characteristic wild species. This study was designed document reproductive tract morphometric dimensions characteristics C. during spawning non-spawning seasons Lake Alau, Maiduguri,...

Effective management is essential for small-scale fisheries to continue providing food and livelihoods for households, particularly in developing countries where other options are often limited. Studies on the population dynamics and stock assessment on fishery target species are thus imperative to sustain their fisheries and the benefits for the society. In Lake Koka (Ethiopia), very little is...

the effects of dietary supplementation of garlic (allium sativum)extract on the growth and disease resistance of african catfish, clarias gariepinus was evaluated. also in-vitro evaluation of susceptibility of fish-borne multidrug resistant (mdr) pathogenic bacteria to aqueous extract of garlic was done. aqueous garlic extract exhibited inhibitory activity against mdr bacteria and the degree of...
