The effects of Lead Nitrate on catalase (CAT) production levels in post juvenile Clarias gariepinus were investigated. A total of 250 samples of the fish were acclimatized for two week. Six samples of the fish were exposed to the sub-lethal concentrations of 00, 28, 43 and 57 mg/L with replicate in each case for 28 days. Two samples of the fish were randomly selected from the treatments and control for the bioassay of... Read more.

There is evidence that ammonia, hydrogen sulphide and dissolved oxygen are implicated in fish kills occurring on the Lake Malawi shores of Karonga town. Exposure to fish is influenced by strong winds while water temperature differences cause upwelling and fish mortalities in surface waters. The vulnerability of fish in Karonga town to physico-chemical factors was computed from secondary sources data obtained in 2000 to... Read more.

The lack of better performing native fish species for aquaculture led the government of Malawi to import the exotic common carp (Cyprinus carpio L.) from Israel in 1976. Growth trials at Domasi and Kasinthula Experimental Stations had shown that common carp grew faster and to a larger size than the indigenous fish species. The government decided to distribute the fish to farmers for grow-out. Barely five years into... Read more.

Fisheries management continues to be a nightmare due to over exploitation of fish stocks and various anthropogenic activities resulting in a reduction of genetic resources. Opsaridium microlepis, a commercially exploited fish species from Lake Malawi, is no exception, hence it is listed among as endangered species. Opsaridium microlepis stocks from four different rivers, were analyzed using 13 geometric morphometric... Read more.

The present study evaluated the impact of varying dietary linseed oil composition on growth, survival and tissue polyunsaturated fatty acids (PUFA) profiles in Nile tilapia (Oreochromis niloticus). Five iso-nitrogenious diets with varying linseed and sunflower oil concentrations were formulated and fish fed twice daily to for 3 months. Commercial diet was used as a control in triplicate tanks set for each diet... Read more.

This paper revisits and builds on the work of Ishmael Kosamu, Wouter de Groot and Patrick Kambewa who, in 2016, proposed a management system for the Elephant Marsh Wetland Fishery in Malawi, and identified key issues that would help the fishery to be sustainable in the short to medium term. They postulated that a sustainable three-pillared (locally based, weak, and amorphous) institution for the Elephant Marsh Wetland... Read more.

Oreochromis variabilis Boulenger (1906) is an indigenous and critically endangered fish species of Lake Victoria. It is among the species targeted for stock enhancement and restoration in Kenya. Such mass stock enhancement requires simple and easily applicable techniques to maximize its larviculture. This study investigated the growth potential of O. variabilis from fry to fingerling stages using diets formulated from... Read more.
