Determination of Mineral Contents of Edible Parts of Shellfishes from Okpoka Creeks in Rivers State, Nigeri

Articles, Uncategorized /

The study was conducted to determine the mineral contents of some selected shellfishes from Okpoka Creek in River State. Copper, iron, manganese, calcium and sodium were quantified using Atomic Absorption Spectrophotometric method and the concentration of the minerals varied between the different species of shellfishes. High amount of calcium was recorded in C. guanhumi (212.33±1.45mg/100g) […]

Dietary Sorghum Starch Influences Growth Performance, Apparent Digestibility Coefficient And Some Hepatic Enzyme Activities Of Carbohydrate Metabolism In Hybrid Red Tilapia (Oreochromis Mossambicus × O. Niloticus) Fingerlings

Articles, Uncategorized /

A 120-day feeding trial was conducted to investigate the effects of dietary sorghum starch on growth performance, feed utilization, apparent digestibility coefficient (ADC) and some hepatic enzyme activities regulating glycolytic and gluconeogenic metabolic pathways of fingerlings hybrid red tilapia (Oreochromis mossambicus × O. niloticus) with initial body weight of 10.9±0.2 g. Five isonitrogenous and isolipidic

Suturing as an Alternative to Sacrificing Male Catfish in Artificial Fish Breeding: Short Communication

Articles, Uncategorized /

In artificial catfish breeding, unlike other fin fish, as a result of the presence of the convoluted vas deferens attached to the testis, spontaneous release of semen does not occur and hand stripping of the male does not yield any result. Since neither natural nor hormone induced breeding of catfish is capable of mass producing

Comparison of Zooplankton Community Structures in three Polyculture Models of Ponds Stocking Ctenopharyngodon Idellus

Articles, Uncategorized /

The Zooplanktons community structures in three polyculture models of pods, stocking mainly grass carp (Ctenopharyngodon idellus) were enumerated. We focused on the variability of a zooplankton community structure and compared its differences in the three polyculture models. Environmental factors and zooplankton abundance differed significantly among models. Nevertheless, model 2 had the minimum biomass of crustacean

Morphological Variation of Cichlids from Kainji Lake, Nigeria

Articles, Uncategorized /

This study was designed to evaluate morphological variations of cichlids from the Kainji lake, Niger State in Nigeria. 200 samples of cichlids comprising four species (Oreochromis niloticus, Tilapia zilli, Pelmatolapia mariae and Sarotherodon galilaeus) were collected from the lake and a total of thirty morphometric measurements and meristic counts were recorded. Data was corrected to
