From its inception in 1962, the University of Lagos has been identified as a potential centre for the development of Marine Biology and Fisheries in Nigeria. At that time, it was the only University/ Institution in Nigeria situated by the sea and it was obvious that it was most suitable for the development of such disciplines. In the absence of a Faculty of Agriculture and taking full benefit of its location by the sea, lagoon and river, the University of Lagos is one of the very rare institutions in the world suitable for the establishment of a Marine Biology and Fisheries programme.

    Biotechnology and Species Development in Aquaculture.
    (Academic Journal, 2008-09-30) Ayoola, S. O.; Idowu, A.A
    The use of biotechnology in various aspects of human endeavour have obviously created a great impact but not without some risks. Not withstanding, there is still the need for its adoption as more of the already adopted biotechnologies are being improved upon with lesser demerits. Aquaculture is not also left out in the application of biotechnological approaches. The aquaculture industry is currently faced with solving the simultaneous problems of developing economically viable production systems, reducing the impact on the environment and improving public perception. Whereas significant progress has been made in understanding production systems, improvement in cultured stocks has not kept pace with productivity demands. This paper considered aquaculture as the only way to increase fish production and also discusses technical environmental and management considerations regarding the use of genetically modified fish organism (e.g. fish) in aquaculture. This paper discusses advantage of biotechnological research application and commercialization.

    Sustainable Fish Production in Africa
    (African Scholarly Communication Trust(ASSCAT)/Rural Outreach Programme, 2010-05) Ayoola, S. O.
    Fish farming is today considered an important source of production for meeting world’s increasing demand for protein. Fish is an important source of good quality protein required in human diet. It has the highest level of easily metabolisable high quality protein, fats, vitamins, calcium, iron and essential amino acids when compared with other sources of animal protein such as poultry and beef. Fish consumption is highly relished among people of all classes and ages in that the fish is less tough and more digestible when compared to beef, mutton chicken and bush meat. This is due to the greater ratio of muscle protein to connective tissue protein in relation to other animals. Fish possesses excellent amino acid balance with high digestibility percentage of about 87 – 98% compared to 87 – 90% recorded for beef and poultry. In addition, fish is very important to the developing world population as it is the major source of cheap high quality animal proteins which are very vital for healthy development. Fish production is relatively inexpensive when compared with other sources of animal protein such as cattle, pig and poultry. In view of the facts that most of the health related problems in developing world such as abnormal development, reduction in human productivity, high incidence of infant mortality, malnutrition and diseases have been attributed to low intake of good quality animal protein, this has made production of fish very imperative to the good health of the nations in the developing world. Fish farming has a lot of potentials to sustainable development. Fish as a source of rich food for the poor can play a crucial role in improving the food security and nutritional status of the millions of the people in Africa and other developing part of the world. The present low level of fish production in Africa can be increased sustainatially by adapting a technological shift from extensive to intensive system of production as is the trend in developed countries

    The Willingness of Secondary School Students to Choice of Aquaculture as a Career in Okitipupa Local Government Area of Ondo State, Nigeria
    (Department Of Forestry, Wildlife & Fisheries Management, Ekiti State University, Ekiti, 2012) Ogunremi, J.B,; Ayoola, S. O.; Kareem, A.O; Adesina, B.T
    This study examined the willingness of secondary school students to choice of aquaculture as a profession in Okitipupa Local Government Area of Ondo State, Nigeria. The sample was made up of 100 science students randomly selected among science students in two public secondary schools. Questionnaire was used in data collection. Data were analysed by the use of frequency counts, percentages and Chi-square. The findings revealed among others that 52% of respondents were aware of Aquaculture as a profession, 56% were willing to study aquaculture with the award of scholarship; gender and parental educational level are not significant to the willingness of secondary school students to study aquaculture (p>0.05). It follows that interest of students in the profession should be aroused starting from the secondary school levels. Based on this study, it is recommended that Governments, public and private organizations, individuals and NGOs should embark on various enlightenment programmes and motivation of students at secondary schools to encourage the study of aquaculture as a profession.
