The potential of aquaculture development in the fishing communities of the State of Anambra.
This study examines the potential for aquaculture development in the Anaku community, Ayamelum in the state of Anambra, Nigeria. A structured interview plan (questionnaire) was used to collect relevant information from the respondents.
Analysis tools used include descriptive statistics (frequency table, bar graph, and percentage), chi-square, and ANOVA with SPSS version 20.
The results of the study show that there is a significant correlation (P0.05) between the socio-economic characteristics of the respondents and the aquaculture activities. 82.5% of men work in fish farming, while 17.5% women work in fish processing and trading. 77.5% were traditional worshipers, while the active working age was between 24 and 40 years. 58.75% of the respondents practiced fishing as the only source of income. 50% of the respondents used their local fishing gear such as a net, hook and line. 100% of those questioned used natural waters for fishing. 85.0% of the buyers surveyed came from outside the village.
However, the challenges include: lack of access to credit, lack of access to materials, high material costs and no formal training, insufficient equipment, lengthy type of fishing, lack of fisheries extension services and government support, lack of cold storage and standard market.
Data on physicochemical properties, heavy metals and biological parameters were analyzed to determine the suitability of water for the development of aquaculture.
The study showed that the temperature was between 27.33 ± 0.577ÖC, turbidity between 49.80 ± 5.702 cm, nitrate between 1.06.00 ± 0.529 mg / l, ammonia between 0.53 ± 0.033 mg / l. The pH is between 6.77 ± 0.057, the oxygen content between 99.33 ± 0.57 mg / l, the lead content between 0.123 ± 0.015 ppm, the cadmium between 0.133 ± 0.003 ppm, the mercury between 0.861 ± 0.101 ppm and the zinc between 0.518 ± 0.026 ppm and the iron between 7.436 ± 0.588 ppm.
The study found that the physicochemical parameters, with the exception of nitrate, were within the tolerable limit, while the heavy metals, with the exception of zinc, were above the tolerable limit.
There was plenty of phytoplankton and zooplankton. One of the recommendations in this study is that people should be trained on the risk of dumping garbage in the river.
Activities should aim to reduce or avoid pollution of the river through the enforcement of environmental laws. Integrated agriculture can be adopted because it grows rice and other agricultural products.
Aquaculture is growing rapidly every day and then becoming an ever larger industry every year. Therefore, it is increasingly important for anyone working in this industry to understand the basic part of water production facilities.
Aquaculture requires knowledge and skills on the many general aspects of production such as spawning, animal feed production, etc. (Anderson, 2004).
Fishing is an important sector in Nigerian agriculture, which provides valuable food and employment for millions of people and, above all, serves as a livelihood for women in coastal communities, as fish is becoming increasingly important as a source of high-quality animal protein Nigeria (Nwuba et al., 2009).
Coastal fishing is important and contributed at least 40 percent to fish production from all sources in Nigeria between 1995 and 2008 (FAO, 2010).
According to the Fisheries Society of Nigeria, small-scale fishing accounts for more than 82 percent of the domestic fish supply and provides livelihoods for one million fishermen and up to 5.8 million secondary-sector fishermen who process, maintain, market and distribute.
In view of Nigeria’s enormous water resources, human capital and other natural resources, the Federal Department of Fisheries (FDF) estimated fish production to be over 1.7 million tonnes, including 201,300 million tonnes on land (brackish and inshore fishing) and 33,900 million tonnes (offshore Fisheries), 288,200 (inland fisheries) and 1180,215mt (aquaculture).
Nigeria is blessed with numerous waters that range from the sea (Atlantic) to brackish water (delta rivers and estuaries) to fresh water inland (rivers, streams and lakes).
Despite these available resources, recent trends have shown a decline in Nigerian catch fishing, and this requires the development of aquaculture, particularly in fishing communities, as they have the potential.
Aquaculture is supposed to be the rational breeding of aquatic organisms (fish, shrimp, shrimp, water snails) in a closed and fairly shallow body of water in which all of its life processes can be controlled.
It is an important sector for the country’s economic development at a time when the government is looking for ways to diversify the economy from a pure oil base. According to Ayinla (2012), aquaculture is the fastest growing food industry in the world.
