Aquaculture research: technology transfer for rural development in Nigeria

Conventional aquaculture has been promoted in Nigeria for the past five decades with minimal impact on rural communities: from the findings of Maclearen (1949) where he popularized the use of culturable fish predators Lutjanus sp; Pomades sp; Tarpon adanticus; Chrysichthys nigrodigitatus in earthen ponds near Onikan-Lagos, Nigeria; to the finding of Zwilling, 1963, who reported common carp, Cyprinus carpio propagation and culture in Panyan Fish Farm, near Jos; to the findings of FAO, 1965, when the potential culture of marine mullets culture in brackish water ponds in Buguma, Rivers State was presented. The work of other researchers Sivalingam, (1970; 1973), Ezenwa (1976), development officers and extension officers contributed to the development of aquaculture in few rural areas of the country and informed on public and private owned fish farm infrastructures. Despite a moderate long history of aquaculture research and development in Nigeria, an annual production level of 25,000 metric tons was recorded in 1999. This situation calls for a more sustainable approach for a stronger link between aquaculture research and technology transfer for the development of rural communities of Nigeria. This paper therefore examines some of the issues involved in the continuous flow of the new aquaculture technology in the improvement of fish protein output, standard of living of rural farmers and prevention of urban migration by the youth

Application of participatory rural appraisal (PRA) techniques in the verification of fisheries data and trend on Lake Kainji

After several years of surveys on the Kainji Lake fisheries activities by the Nigerian German Kainji Lake Fish promotion Project (KLFPP) trends regarding catches, yield and other parameter begin to emerge. However, it became obvious that some of the data were not quite as accurate as they were believed to be. Looking at the different editions of the statistical bulletin of Kainji Lake, concerning one given fisheries parameter, sometimes it is possible to reveal inconsistencies and unexplained trends. As compared to the survey method, PRA is primarily for analysis of differences in local phenomenon and processes. Therefore, PRA was used as a complementary tool to enhance the knowledge on issues like fisher women, entrepreneurs, gear ownership structure, mode of operation by owners of large gear number, preference in the use of twine and nylon gill nets, and reasons for misinformation on the number of fishing equipment owned by entrepreneurs, which cannot be done with frame survey. PRA techniques like timeline, mapping, seasonal calendar, transect walk and key informant interviews were utilized in the study process

Improved fisheries technologies and approaches for their dissemination: a case study of Niger State

Technology generation and dissemination are important components of rural transformation programmes. Nigerian fisheries sub-sector is still hampered by low productivity (especially in aquaculture) and low output (capture fisheries and post-harvest technologies). Research institutions and the Universities have made efforts in developing improved technologies to find solution to these problems, yet the level of adoption of the technologies remain low. This is due to a combination of various factors among which are faulty agricultural policies; institutional framework and unfavourable socio-economic environment. Niger State plays an important role in production in Nigeria and host the only research institute with the mandate in inland fisheries. It is important therefore to know the effectiveness of various extension approaches used in disseminating the technologies developed and their impact on adopters. Forty fishers were randomly selected in Shiroro L.G.A. of the Niger State and interviewed. The study probed into their socio-economic characteristics, traditional practices, extent of awareness and adoption for fisheries technologies and the effectiveness and impact of various approaches used by the extension organizations to disseminate the technologies. The results show that the economically active age group of the fishers was in the range of 20-50 years (87.5%). Males (95%) dominate the fisher population. 47.5% of the respondents have average household size of 6-10 and 57.5% were below primary school in educational attainment. Only 57.5% belonged to cooperative societies, while 90.0% of the fishers have no access to credit other than personal finance. Majority of fish-farmers (60%) operate at homestead level with pond size less than 50 square meter, stock under polyculture fishing methods are at subsistence level, while 67.5% of processors use mud-oven to cure, by smoking, freshly caught fish. Disseminated aquaculture technologies have low level of awareness (5-20%) and adoption (2.5-22.5%). For capture fisheries and post-harvest technologies awareness levels of 47.5-72.5% and adoption levels of 27.5-50.0% were recorded. Method demonstration (87.5%), result demonstration (75.0%) and field days (47.5%) are the major approaches used by the ADP. Respondents were of the opinion that method demonstration (65%), result demonstration (57.5%) and field day (30.0%) are effective. 62.5% of respondents had enhanced income due impact of extension activities

Small-scale fisheries resources management options - an overview: a key note address

Small-scale fisheries is traditional and rural based. Therefore, the paper is an over view of small-scale fisheries resources management in Nigeria. It provides about 80-90% employment to surrounding population. The small-scale fisheries are grouped in to two major sectors:- the artisanal or capture fisheries and aquaculture farming. The paper identified some management problems such as:- multi uses of the water bodies, lack of or inadequate data upon which sound management strategies are based, ownership of inland water bodies is a problem, uncontrolled exploitation hampers sustainable development, poor and low technology and lack of capital, land and credit facilities. The paper presented some management options for sustainable management. Measures to reduced fish spoilage have been advanced. Also highlighted is the role of fish culture in small-scale fisheries management

The role of extension in fisheries development among rural communities

It is a common knowledge that there exists a wide gap between domestic fish production and demand in Nigeria. Government recognizes this situation and has in recent years encouraged fish production through fishing inputs subsidies, DFRRI assisted fingerlings production among others. Despite these efforts, impact at the grassroots has been low. One of the major reasons for the failure could be attributable to inadequate involvement of rural communities in fish production. This missing link appears to be ignorance of local communities in harnessing this potential to stimulate fish production. There is therefore the need to educate the rural dwellers through effective extension services. Strategies to achieve the required awareness have been discussed

The Coastal Barrier Island Network (CBIN): Future management strategies for barrier islands

Barrier islands are ecosystems that border coastal shorelines and form a protective barrier between continental shorelines and the wave action originating offshore. In addition to forming and maintaining an array of coastal and estuarine habitats of ecological and economic importance, barrier island coastlines also include some of the greatest concentrations of human populations and accompanying anthropogenic development in the world. These islands have an extremely dynamic nature whereby major changes in geomorphology and hydrology can occur over short time periods (i.e. days, hours) in response to extreme episodic storm events such as hurricanes and northeasters. The native vegetation and geological stability of these ecosystems are tightly coupled with one another and are vulnerable to storm-related erosion events, particularly when also disturbed by anthropogenic development.

The island of Kauai, Hawaii's progressive shoreline setback and coastal protection ordinance

Approximately two-thirds of coastal and Great Lakes states have some type of shoreline construction setback or construction control line requiring development to be a certain distance from the shoreline or other coastal feature (OCRM, 2008). Nineteen of 30 coastal states currently use erosion rates for new construction close to the shoreline. Seven states established setback distances based on expected years from the shoreline: the remainder specify a fixed setback distance (Heinz Report, 2000). Following public hearings by the County of Kauai Planning Commission and Kauai County Council, the ‘Shoreline Setback and Coastal Protection Ordinance’ was signed by the Mayor of Kauai on January 25, 2008. After a year of experience implementing this progressive, balanced shoreline setback ordinance several amendments were recently incorporated into the Ordinance (#887; Bill #2319 Draft 3). The Kauai Planning Department is presently drafting several more amendments to improve the effectiveness of the Ordinance. The intent of shoreline setbacks is to establish a buffer zone to protect shorefront development from loss due to coastal erosion - for a period of time; to provide protection from storm waves; to allow the natural dynamic cycles of erosion and accretion of beaches and dunes to occur; to maintain beach and dune habitat; and, to maintain lateral beach access and open space for the enjoyment of the natural shoreline environment. In addition, a primary goal of the Kauai setback ordinance is to avoid armoring or hardening of the shore which along eroding coasts has been documented to ultimately eliminate the fronting beach.

Linking public perceptions of socioeconmic change and marine resource management in rural Maine

Rural coastal regions across the United States are coping with dramatic social and environmental changes. Historically, these areas relied heavily on fishing and marine commerce and these economic activities defined the character of coastal communities. However, shifting ocean and climate conditions, together with inadequate management strategies, have led to sharp declines in harvestable marine resources. These trends, along with increasing competition from aquaculture and international sources of fish, have led to the steady decline of fishing as the central economic activity in many rural coastal communities.

Characterization of rural livelihood of Lake Chad basin fishermen

The study examined the characterization of rural livelihood of the fishermen in the Nigeria portion of Lake Chad Basin are as part of European Commission (EC) founded project entitled "Sustainable development of continental fisheries; a regional study of policy options and policy formation mechanisms for the Lake Chad Basin" Wealth ranking exercise which was not based on real income but on production capacity of the fishermen was carried out in twenty (20) villages survey on the western part of the region using Rapid Rural Appraisal Technique with semi- structured interviews. The different activities carried out by the villagers for living were identified according to their socio-economic status. This was followed by an assessment of the socio-economic characterization within each wealth group. Series of comparative analysis of the ethnic composition, accessibility of fishing gear ownership by the population were done. The results show that the 3 wealth groups in the region include the rich (Group 1) the middle class (Group 2) and the poor (Group 3). It was identified that fishing is just one component of the socio-economic production system along side farming, livestock rearing and trading which are closely integrated. The diversified livelihood system being practiced in the Chad Basin region are not only less vulnerable but also more sustainable

Poverty alleviation and rural development in Nigeria: a gender perspective

The paper examines the concept of the feminization of poverty and reviews the limited evidence on the extent of poverty among women. It then examines the arguments that poor women can be highly effective change agents for the eradication of poverty. However, all the women may be considered as instruments for eliminating poverty, lack of understanding an appreciation of the impact of their sex roles and of gender roles and stereotypes continue to prevent the realization of this potential. Therefore, the paper moves on to summarize the differences between sex and gender and examines how both women's sexes roles and the imp gender roles and stereotypes lead to the feminization of poverty and exclude women from the participation in development and programmes to eliminate poverty. The paper reviews the major approaches: women in development or WID, gender and development or GAD and extension of GAD known as mainstreaming. Finally, it considers the issue of poverty, women and gender in Nigeria. It also advances a number of recommendations on women and gender poverty and rural development for the consideration of policy-makers in Nigeria

Occupational practices and problems of rural artisanal fisherfolks in Oyan Dam area of Ogun State

Artisanal Fish Societies constitutes one of the poorest societies in the developing world. Attempts to harness the potentials of the societies have often failed due to the enormity of the problem of poverty. This study was conducted in four major fishing villages namely; Abule titun, Apojola, Imama Odo and Ibaro in order to investigate the occupational practices and the problems of rural artisanal fisherfolks in Oyam's Dam, area of Ogun State. Eighty respondents were randomly selected among the artisanal fisher folks for interview using interview guide. The findings revealed that 43.8% of the fisherfolks are within active range of 31-40 years while 30% are within 21-30 years range. Also 31% had no formal education indicating a relatively high level of illiteracy among the fisherfolks while majority of the respondents practice fishing activities using paddle and canoe. It was similarly discovered from the study that the most pressing problems of the fisherfolks is the lack of basic social amenities like electricity, potable water, access roads, hospitals and markets. It is therefore recommended that basic social infrastructures be provided for the artisanal fishing communities in order to improve their social welfare, standard of living and the capacity to have a sustainable fishing occupation in the interest of food security and poverty alleviation

Evaluation of woman fisherfolks involvement in fisheries activities in Kainji Lake basin

The extent of rural women fisherfolks contribution to fisheries was grossly under estimated and certainly under valued. The basis of their involvement in fisheries activities is to make themselves equal partners to men productive and self reliant participants in the process of improving their own and their family living standard and to enable them realize their full potentials. This survey is informed a system of data collection with the aid of questionnaires and analysis. Ninety-six of the questionnaires were administered to women fisher folks in eight fishing communities selected at random. Thirty seven (97) percent of the women fisher folks are between the ages of 25-35 years, 59.4% of them can only read and write in Arabic language and 21.9% only are literature in western education, which is a general characteristic of the rural population in Nigeria. 24.0% of the respondents are in full time fishing activities while 65-5% are fishmongers. They belong to cooperative societies but only 26% indicated to have benefited from loan and credit facilities. 84.4% of the respondents are sustained by the business. The major problems facing women fisherfolks includes poor market price, fish spoilage, high transport cost and lack of access to loan and credit facilities and extension assistance. Solution to these problems will increase their status benefit and development

"Rapid and dramatic changes in vegetation" of a small pond on Holy Island (Northumbria): Chaotic dynamics?

This note describes changes to the relative extent of four structurally dominant submerged macrophytes in a pond on Holy Island National Nature Reserve, Northumbria, between 1991 and 1998. The estimated extent of the four submerged macrophytes and bare substratum between 1991 and 1998 showed dramatic changes with no obvious pattern or periodicity, as well as no identifiable natural or anthropogenic causes. Chaotic variation may be an important character of submerged pond plant populations, so that surveys taken in a single year may give an unreliable picture of plant populations.
