Hot on the heels of the launch of the floating raft cage culture system in November and an awareness building event for locally produced tilapia targeted at restaurants and supermarkets two weeks ago, last week, Devant Maharaj, the Minister of Food Production in Trinidad unveiled three other initiatives.
In his unprecedented and unrelenting efforts to support the long neglected Aquaculture Sector, Minister Maharaj commissioned a refurbished facility originally established in the 1950’s and re-branding it as the Aquaculture Demonstration Centre.
At the same event, there was also the signing of a MoU among several of his Ministry agencies and the predominant farmers group for the purchase of farmed tilapia, processing of the fish and subsequent sale of the product under a newly created TT Tilapia brand. These are all bold and never before seen initiatives in the aquaculture industry anywhere in the world and many countries would do well to pay attention to this model for aquaculture support and development.

Though introduction of tilapia in Nepal has passed over a decade, its cultivation has not flourished. There is a general fear of displacement of indigenous fish species. Swar and Gurung (1988) found the reduction of 42 % in the yield of Mystus spp. and Puntius spp. after introduction of bighead carp (Aristichthys nobilis), silver carp (Hypophthalmichthys molitrix) and grass carp (Ctenopharyngodon idella) in the Begnas lake of Pokhara valley. But biology of tilapia favors for its cultivation in Nepal. The climatic condition in hilly regions can control to an extent the over breeding activity of the fish. The minimum temperature of tolerance for Tilapia is 10ºC – 11ºC. It cannot survive below this temperature. The physiological condition can easily be exploited in Nepalese subtropical climate to control the population of tilapia.
For cultivation of the fish, coldwater bodies can be selected where temperature is rather favorable during summer for growth. Those water bodies can be used for stocking tilapia for 7-8 months and the fish would be harvested during winter months. Temperature below 10ºC will kill the remaining fish after the harvest and there will be no fear of wild propagation. Their population will be controlled naturally.
Terai region can be utilized for brood fish stocking and seed production. In this way seed production in Terai and grow out production in hilly region will be the best combination for tilapia cultivation without the fear of displacement of the indigenous fish species of the country.
Polyculture opportunities in the mid-hills of Nepal for resource poor farmers

Nepal is a country of intense poverty and political upheaval. Many people live below the poverty level and there are many nongovernmental organizations at work within the borders of the country attempting to decrease the number of poor through the arming of the people with the tools necessary to become self-sufficient and raise their income levels while at the same time doing so in a way that improves social cohesion and the overall health of the population. I examined various methods and protocols for improving the living standards of the resource poor farmers with a focus on the utilization of aquaculture as a means to improve income, supplement diet and provide social stability and personal growth. The paper presents a suitable low cost solution to the issues facing resource poor farmers in Nepal through the establishment of an aquaculture network, with less reliance in inputs than more intensive practices.

A project to identify Nile tilapia ‘super strains’ in the Philippines will help to increase the living standards of poor fish farmers and consumers, create new employment opportunities and provide food security across the nation.
Nile tilapia (Oreochromis niloticus) is the most cultured freshwater fish in the Philippines, and the tilapia industry provides valuable income and an affordable source of animal protein for the growing population, including many of the 30 million people that FAO estimates depend on agriculture and fishing for a living.
About to enter its second year, the project entitled “Evaluation of Nile Tilapia Strains for Aquaculture in the Philippines” is lead by WorldFish in partnership with, the Freshwater Aquaculture Center from Central Luzon State University (FAC-CLSU) and the Bureau of Fisheries and Aquatic Resources – National Freshwater Fisheries Technology Center with funding from the Bureau of Agricultural Research.
Dr. Tereso Abella, Director of FAC-CLSU and technical consultant from WorldFish says that identifying the best performing strain in the country will have vast social and economic benefits.
“The goal of the project is to develop and make available the best strain of Nile tilapia for the industry. We want the product of this research project widely disseminated to both large and small-scale tilapia farmers but higher priority will be given to small scale tilapia farmers to improve their production, and the quality of their lives,” he says.
This will help increase aquaculture productivity, generating greater income for small-scale fish farmers, improving their living standards, and helping to increase the availability of Nile Tilapia for poor consumers. It is also expected to contribute to gender equality through the creation of employment opportunities for women.
“Tilapia in the Philippines is the fish of yesterday, the fish of today and the fish of tomorrow. It is the people’s fish because it’s readily available, accessible and affordable to every ordinary Filipino,” adds Dr. Abella.
