Growth Performance, Gonadal Weight and Fecundity: A Comparative Study of Rastrineobola argetea and Roasted Soybean Meal as Protein Ingredients for Brood Stock African Catfish (Clarias gariepinus) in Uganda

Robert Muyinda, Henry Felix Emejje, Gerald Zirintunda, Keneth Iceland Kasozi, Abel Patrick Mawadri
Rastrineobola argetea (fishmeal) was compared to roasted soybean meal as protein ingredients for brood stock African cat fish (Clarias gariepinus) in March 2019 on Geossy farm, Uganda. The fish were observed for growth and reproductive indices. Brood stocks of average weight 327 g were fed on different feeds for a month. Feed A contained soybeans as the sole main protein source. Feed B contained fishmeal as the sole protein source. Feed C was the control (usual farm feeds). Growth indices of B w...

Physical and Chemical Parameters and Some Heavy Metal for Three Rainy Season Months in Water and Sediments of Upper New Calabar River, Niger Delta, Nigeria

Awoteinm Dateme Isaiah George, Jasper Freeborn Nestor Abowei
The study of heavy metals in water and sediment was carried out in the upper reach of the New Calabar River, Niger Delta region in Nigeria. Three sampling stations were selected which were Choba, Ogbogoro and Aluu. Water and sediment samples were collected and analysed, using the buck scientific Atomic Absorption/Emission spectrometer 200 A model. Water Physico-chemical parameters were measured i

The Recruitment Pattern of Liza falcipinnis from Elechi Creek, Upper Bonny, Niger Delta, Nigeria

Awoteinm Dateme Isaiah George, Jasper Freeborn Nestor Abowei
The Recruitment Pattern of Liza falcipinnis from Elechi creek of Upper Bonny, Niger Delta, Nigeria was studied from (March 2009-January 2010). The pattern showed all year round recruitment with two peaks (one major and one minor) during the period of the study. The parameters obtained were L = 19.96, K = 0.40 y

Density-Dependent Effect Occurs Regardless of Density

Kazumi Sakuramoto
Maximum sustainable yield (MSY) is the most important concept in fisheries resource management. MSY can be established based on the concept of the density-dependent effect. However, the concept that a density-dependent effect controls the fluctuation of the population living in the ocean is controversial. This paper discusses the validity of the density-dependent effect focusing on the stock-recruitment relationship (SRR). In many

An Assessment of Some Heavy Metals in Sediment of Otamiri River, Imo State, South-Eastern Nigeria

Adebayo Ebenezer Temitope, Lawrence Azubuike Ebeniro, Ajiboye Gabriel Oyediran, Tope Joan C-Oluwatosin
An assessment of some Heavy Metals in Sediment of Otamiri River, Imo State, South-Eastern Nigeria was conducted between the months of August to October, 2015. Water samples were collected from four sampling stations established along the river channel for 3 months (fortnightly). Physic- chemical parameters were analyzed following conventional field and standard laboratory techniques. Temperature range between 24.25℃ - 30.50℃, Hydrogen ion mean concentration value of 7.01 ± 0.19 ppm was obtained,...

Improving Food Security in an Eco-Friendly Manner through Integrated Aquaculture

Olawale Ahmed Onada, Oluniyi Solomon Ogunola
As the global population increases, demand for food, most especially protein, will increase. The increasing production from agriculture, including forestry and fisheries, has, however, contributed significantly to global food security but most often at the expense of environmental deterioration. Integrated aquaculture (IA) can guarantee and sustain adequate food security in environmentally friendly manner. Integrated fish farming is a diversified and coordinated way of farming with fish as the m...
