FISHERY & AQUACULTURE TOPICS

ABSTRACT

Nigeria has over three thousand Ornamental Fish species and the potential of being one of the leading exporters. In spite of the flourishing trade of Ornamental Fish worldwide however, her extant share of the trade is below 5% of Africa‟s total contribution. In addition, there is paucity of information on the marketing factors influencing Ornamental Fish trade in Nigeria. The marketing channel and factors influencing Ornamental Fish trade in Nigeria were therefore investiga...

Abstract

Wild brood-stock is a major genetic reservoir for sustainable culture of Clarias gariepinus. This has been observed to be declining in major freshwater dams in Nigeria. There is inadequate information on factors responsible for this decline and their effects on genetic structuring of the fish resources in these dams. This study therefore investigated genetic structure of C. gariepinus in relation to environmental condition of Asejire Dam. The Dam was spatially divided into...

ABSTRACT

High cost of feed and competition between fish and other livestock‟s feed industries necessitate research into low cost, non-conventional feedstuffs for profitable fish farming. The feed potential of Mucuna utilis in this direction has not been documented. The feed potentials of Mucuna utilis and its effects on growth and biochemical parameters of the African catfish, Clarias gariepinus were therefore investigated. Proximate, mineral composition and level of L-DOPA (3, 4-di...

Background to the Study

In Nigeria, the primary role of Colleges of Education is to train teachers who will after completion, be awarded the minimum teaching qualification of Nigeria Certificate of Education (NCE). This certificate qualifies one to teach in Junior Secondary and Technical Colleges and the programme has duration of three years. These teachers‟ Institutions were formally known as Advanced Teachers Colleges and were affiliated to different Universities...

ABSTRACT

This study examined the total replacement of fishmeal (FM) with poultry hatchery waste meal (PHWM) in practical diets for African catfish (Clarias gariepinus). Five iso-nitrogenous diets containing levels Diet1, 0% (control); Diet 2, 25%; Diet 3, 50%; Diet 4, 75% and Diet 5, 100% of PHWM as a replacement for FM were fed to three replicate groups of African catfish with an initial weight of 5.1±0.01 grams. Diet 5 (100% PHWM) has the best grow...

Abstract

This study was carried out on small scale fisheries in Nigeria. In the past three and a half a century since fisheries development was embarked upon in West Africa, the significant contributions of women in sustaining the socio-economic livelihoods of their families has been neglected and taken for granted. The aims of the study were to describe socio-economic characteristics of respondents, determine their roles in artisanal fishery, identify their marine...

BACKGROUND TO THE STUDY 
Aquaculture is the husbandry of aquatic food organisms. The need arose from the decrease in supply from ocean fisheries as a result of over-fishing, habitat destruction and pollution. One of the ways to bridge the gap between the reduced fish supply and increased world food fish demand is through aquaculture. Africa including Nigeria has little aquaculture tradition and has been affected by a number of external problems that have prevented...

ABSTRACT

The major indigenous method of fishery in Nigeria is the artisanal fishery using set-gill nets, beach seines, long line, basket traps, cast nets, however This indigenous fishery as being practiced now is labour intensive and because of the limited capabilities of the craft and gear results in low productivity.The constraints to the development and management of the indigenous fishery sector in Nigeria were well identified when the country&#...

ABSTRACT

This study was carried out on improving technologies for inland aquaculture in Nigeria. To achieve this, three significant research objectives were formulated. The survey design was adopted and the simple random sampling techniques were employed in this study. The population size comprise of civil servants in the ministry of agriculture and rural development in Abuja, Nigeria. In determining the sample size, the researcher conveniently...

ABSTRACT

In this study, our focus was to carryout  a critical analysis on the methods of improving productivity and profitability of smallholder shrimp aquaculture and related agribusiness in Nigeria.

The study adopted the survey research design and randomly enrolled participants in the study. A total of 80 responses were validated from the enrolled participants where all respondent are active shrimp farmers in the Uyo Local governmen...

ABSTRACT

This study was carried out to assessing inland aquaculture in Nigeria: improving fingerling supply and fish nutrition for smallholder farms using in Sagamu, Ogun state as a case study. Specifically, the study examine the level of production in the inland aquaculture sector in Nigeria; identify ways of improving fingerlings supply to smallholder farmers in Nigeria. The study further identify ways of improving the supply of fish nut...

ABSTRACT

This study was intended to assess the economic and welfare values of fish in the lower Niger River. This study was guided by the following objectives; to examine the economic and welfare values of fish in the lower Niger River. To examine the effect of artisanal fishery production on the lower Niger River on the Nigerian economic growth. To identify the limitation of the artisanal fisheries on the lower Niger River. The stu...

ABSTRACT

The study of water quality using macro invertebrates as bio indicators of pollution in the Ikpoba river Benin City, Edo State was carried out for a period of 3months (march-may) in 2013. Water and macro invertebrate samples were collected from three stations (Okhoro), Reservoir and the Bridge.) along the river. Physiochemical variables were determined using standard methods. A total of 652 macro invertebrates were collected. Twenty seven (2...

ABSTRACT

Fish abundance and distribution of three water bodies namely Onah lake, Anwai river and River Niger at cable point was studied. Fish specimens were collected using gill nets, traps, and hook and line  between July-December, 2013. One thousand four hundred and eighty seven fish specimens were collected and brought to the laboratory at Delta state university for further identification using identification  key. The family Mochokidae...

EXCERPT FROM THE STUDY

In contrast to the rest of the world, per capita fish consumption in sub-Saharan Africa including Nigeria has declined to almost half of the global average and despite suitable natural conditions; aquaculture provides only 2 percent of the region‟s supply of fish and little economic growth, employment and foreign exchange (World Bank, 2006). Past aquaculture development efforts have largely failed due to weak institutions, poor access to finance and a heavy re...

Climate is dynamic in the sense that analysis of some relevant climate elements revealed that natural forces have enforced change over centuries (Cunningham and Cunningham, 2004) and such changes are inevitable natural occurrences. However, anthropogenic factors have exacerbated climate change in recent times and the impacts on socioeconomic and livelihoods of people, as well as the mitigation and adaptive measures, are current issues that have attained global dimension.

The indicat...

BACKGROUND TO THE STUDY

The Aquaculture Compendium is an encyclopedic, multimedia tool that brings together a wide range of different types of science-based information to support sound decision-making in aquaculture and aquatic resource management worldwide. It is comprised of information sourced from experts, edited and compiled by an independent scientific organization, and resourced by a diverse international Development Consortium. The datashe...

BACKGROUND TO THE STUDY

Nigeria, the country of many rivers, is also rich in lakes, reservoirs and wetlands but many of them had been degraded due to a lot of factors (FGN, 1993). Sustainable fisheries production and development depends largely upon good aquatic environment. It is generally accepted that the future well-being of a developing country such as Nigeria, will depend upon a much wiser balance between exploitation and conservation of natu...
