The Abundance, Distribution and Diversity of Benthic Invertebrates of Lake Malombe

The benthic zone of Lake Malombe was sampled for invertebrates, fungi and bacteria using an Ekman Grab measuring 15.2cm by 15.2cm. Thirty-six stations were surveyed for macro-invertebrates which were identified to the lowest taxa and enumerated to estimate abundance for the lake. Snails were the most dominant macro fauna, belonging to four genera Melanoides, Bellamya, Bulinus and Lanistes with the mean densities of...

Growth performance and nutrient digestibility of juvenile Clarias gariepinus fed phytase-supplemented soya bean (oil-extracted) and full fat soya bean diet: comparison of phosphorus availability, digestibility and serum parameters

Two experiments were carried out to investigate and compare growth, phosphorus availability, digestibility and serum status in juvenile Clarias gariepinus. Two groups of five isonitrogenous and isocalorific diets containing25, 50, 75, and 100 % soya bean meal (oil-extracted) and roasted soya bean meal, respectively, were formulated and supplemented with graded levels of phytase at 0. 250, 500, 750 and 1000 FTU/g. A fish...

Application of Box-Jenkins models in forecasting annual catch trend of Usipa (Engraulicypris Sardella (Gunther, 1868)) from Lake Malawi

Modelling is a process by which mathematical expression is used to describe a real quantitative situation in a system. The development of scientific understanding through quantitative expression of current knowledge of a system helps managers and planners to make tactical and strategic decisions. The study was designed to model catches for important cyprinid species (E. sardella) from Lake Malawi. The Box-Jenkins approach...

EFFECT OF DUCKWEED AND CHLORELLA ALGAE AS FEED SUPPLEMENTS ON NILE TILAPIA (Oreochromis niloticus) FINGERLING GROWTH IN WATER TANKS AT MENAA FISH FARM IN KISAASI,UGANDA

The use of duckweed chlorella combination as a protein supplement and the subsequent effects on tilapia fish fry would be a good way of reducing production costs in intensive tank tilapia culture. Thus an investigation was staged to identify the effects of duckweed and chlorella algae as feed supplements on Nile tilapia fry growth under the green water technique. Three experimental treatments were run in two replicates for...

Effects of feeding frequency on growth performance, feed utilization and body composition of Oreochromis shiranus juvenile (Trewavas 1983) reared in rectangular fiberglass tanks.

A two months feeding trial was conducted to investigate the effect of feeding frequencies (2, 3 and 4 times/day) on growth performance, feed utilization and body composition of Oreochromis shiranus under laboratory conditions. A total of 180 Oreochromis shiranus fingerlings of 9g were stocked in 9 experimental opaque fiberglass tanks of about 150l of water each. The completely randomized design (CRD) was used in this...

Preliminary Assessment of heavy metal concentration in selected fish feed ingredients

Abstract. Dearth of information exist on the heavy metal concentration (HM) of local fish feed ingredients in Nigeria, thus preliminary investigation on the concentration of lead, cadium (toxic heavy metals), copper, zinc and chromiun(essential trace metals) present in some selected feed ingredients. The two toxic metals; lead and cadium were found in fishmeal at the concentration of 0.30mg/kg each. Cd content in soybean...

Effect of Spirulina meal on Growth and Survival of freshwater Prawn Macrobrachium rosenbergii Juvenile

This study was conducted to assess the potential growth promoting effect of Spirulina on Macrobrachium rosenbergii juveniles. The experimental feed crude protein level was maintained at the level of maximum 32 %. The feed was prepared by fishmeal which was replaced with Spirulina powder at 2.5 %, 5 % and 10 % level, its serve as experimental feed. Without Spirulina feed serve as a control feed. The experiment was prolonged...
