If the problem of environmental pollution and other factors of concern is not resolved, the Nigerian plan to provide enough fish to stop dependence on imports will become a mirage.

This was part of the results of the outstanding expert in the management of incubation, water pollution and toxicology, Professor Bamilda Omitoyin, who delivered the 440th and 14th in a series of introductory lectures for the academic session of 2017/2018 on behalf of the Faculty of Renewable Natural Resources of the University of Ibadan (UI).

In a lecture entitled "Calming the problematic waters of Nigeria: a hope for sustainable fish production," Omovoyin identified oil leaks, discharges from industry and household waste from the boundaries of settlements and other activities along tributaries and watersheds as threats to aquatic life.

Noting that water in Nigeria is concerned, he said that its impact undermines productivity and adversely affects food security through the production of fish.

He said that other critical threats are caused by climate change, floods, intense human activities: such as the indiscriminate use of fertilizers and pesticides in agriculture; urbanization; dams, the construction of roads and bridges; irrigation; extraction of sand; filling of wetlands; population growth and misuse of natural water resources.

Don also stressed that the burning of gas in the delta of the Niger with the release of carbon dioxide (Co2) of about 35 million tons per year contributes to increasing the amount of acid rain in the region.

He said: "The consequences of the problematic waters of Nigeria include the death of aquatic animals, including fins and shells, the disturbance of the food chain due to the disappearance of vulnerable species leading to death and extinction, the contamination of fish by unpleasant smells and tastes caused by oil products, the destruction of a fragile ecosystem of pollution of water and silting caused by erosion or discharge of waste into waterways ".

The expert on renewable natural resources explained: "Nigeria is a maritime state with rich networks of inland water bodies.

Inland waters are among the most extensive with rich and diverse water resources in Africa and the world.

As a maritime state, Nigeria is endowed with rich and diverse marine ecosystems.

The exclusive economic zone of the country (EEZ) of 200 nautical miles is 853 km from the coastline and covers 192,000 km² in an area very rich in fish resources. Known fish stocks in Nigerian coastal waters include, among others, bonga, filament fins, tilapia, tuna and tuna fish.

The potential yield of fish in fresh water is a function of the interaction of abiotic and biotic factors. "

He said: "Fishing resources can be renewed if scientifically substantiated.

On the other hand, when they abuse, they are delicate and can become extinct.

The use of these resources from the waters of Nigeria to achieve the ultimate goal of national development, especially in the field of food security, is hampered by the current state of Nigerian waters, which is deeply concerned about the interaction of human activity caused by activities. "

The teacher of the Department of Aquaculture and Fisheries Management highlighted some innovative research efforts that he used to calm troubled waters of Nigeria for sustainable fish production.

He said that his research efforts with his colleagues led to the establishment of a sustainable integrated aquaculture system with the concept of "zero waste" for food security in West and Central Africa.

This put the University of Ibadan on a global map thanks to a grant for several donors of $ 1 million. USA, coordinated by the Council for Agricultural Research and Development (CORAF / WECARD) in West and Central Africa in 2011 in cooperation with two other universities in West and Central Africa.

The project, Omitoyin, "successfully achieved 100% utilization of waste through the production of larval larvae, fish oil, fish meal and mineral-rich organic fertilizer.

All wastes from the integration process are now being used in a cost-effective and environmentally sound manner.

"More than 45 farmers have benefited from these efforts.

The capacity of 2,800 farmers, 19 research scientists, 5,000 young people and 22 graduate students, 40 per cent of whom were women, was expanded.

10 technologies / innovations were developed and disseminated, and the level of acceptance is more than 60 percent.

This has improved the opportunities used for training and research by 20 percent in the Department of Aquaculture and Fisheries Management at the University of Ibadan. "
