Enhancing the fisheries sector of African Great lakes: Value chain analysis of the Tanganyika Sardine (Limnothrissa miodon, Boulenger 1906) from Lake Kivu, Rwanda

Lake Kivu is experiencing unprecedented decline in production of Tanganyika Sardine (Limnothrissa miodon). This study sought to characterise the value chain of this fish species so as to chart its sustainable utilisation. The study performed in 2015 found two chains; an informal chain that takes 30% of the production and a formal chain that handles 70%. The average catch of sardine was 30 kg/day in the high production...

Aspects of reproductive indices and enteroparasitic infestation of Clarias gariepinus (Burchell, 1822) in a tropical reservoir

The study was carried out between September 2011 and August 2013, using 328 Clarias gariepinus in Oba reservoir, Oyo State, Nigeria. Standard methods were used to determine gonado-somatic index (GSI), fecundity values, and enteroparasitic infestation of the fish. Sex ratio was 1.3:1, male to female, and females on an average invested 20.54% of its body weight in egg production while male GSI was 6.05 ± 0.19%....

Water hardness does not influence iodine-induced mortality of rainbow trout eyed eggs

To evaluate the effects of water hardness on survival to hatch of eyed rainbow trout Oncorhynchus mykiss eggs during iodophor disinfection, hard (300 mg/L CaCl2) and soft water (20 mg/L CaCl2) solutions were used in combination with iodophor treatments of 0, 100, 200, 400, 800, and 1600 mg/L. Water hardness did not significantly influence egg survival-to-hatch. In addition, there was no significant interaction between...
