Recent changes in fish communities of the equatorial Lake Naivasha, Kenya

Changes in fish species composition and abundance in Lake Naivasha were investigated monthly for a period of 12 months. Data were obtained both from experimental surveys as well as commercial fish landings. The structure metrics considered included species abundance and composition, length- frequency and physico-chemical attributes. Results of the study showed that the fishery is currently dominated by the recently...

Temperature-dependent egg development rates, hatchability and fry survival rate of Lake Malawi Tilapia (Chambo), Oreochromis karongae (Pisces: Cichlidae)

A study was conducted to assess the effect of temperature on egg development in an attempt to improve hatching success and fry production in Oreochromis karongae. Temperature-dependent development rates and hatching period for fertilized eggs stripped from O. karongae, a mouth brooder, were determined in a recirculating system set up in a hatchery at the National Aquaculture Center, Domasi, Malawi. Three...

The effects of replacement of fish-meal with crab-meal on growth and feed utilization of African giant catfish Heterobranchus longifilis fingerlings

A feeding experiment was conducted in plastic aquaria (46 ´ 38 ´ 28 cm3) to investigate the effect of replacing fish-meal (FM) with crab-meal (CM) on growth, feed utilization and body composition of Heterobranchus longifilis fingerlings with body weight, 3.11 ± 0.56 - 8.48 ± 1.70 g and total length, 73.07 ± 4.99 - 98.69 ± 7.64 mm. Fish and crab-meal were separately used to produce...
