An investigation of enzyme and other protein polymorphisms in Japanese stocks of the tilapias Oreochromis niloticus and Tilapia zillii
Abstract
Samples of Oreochromis niloticus and Tilapia zillii were collected from the hatcheries of Osaka Prefecture Fisheries Experimental Station and Shiga Prefecture Fisheries Experimental Station, Japan, respectively. The samples were used for screening polymorphisms in 13 enzymes, skeletal muscle proteins and hemoglobins by horizontal starch gel electrophoresis. Among 35 loci examined, 12 loci for the 10 enzymes, sarcoplasmic protein and hemoglobins were polymorphic in O. niloticus and 2 loci for 2 enzymes were polymorphic in T. zillii. The observed numbers of phenotypes for respective loci agreed well with Hardy-Weinberg expectations. The genetic basis for each polymorphism is discussed. This investigation provides basis information on the status of these tilapias in Japan.

Antibacterial activity of tilapia Tilapia hornorum against Vibrio harveyi
-Aquaculture , 2004 - ElsevierDisease due to luminous Vibrio has been a major problem of the shrimp industry. Different technologies have been introduced to control the disease. One of the techniques reported to work against luminous bacteria in the Philippines is the green water culture system (or finfish–shrimp integrated culture system). A green water culture system is an innovative technique wherein shrimp are cultured in water collected from a pond where tilapia or other fish species are grown. In some cases, the fish are cultured in an isolated net pen inside the shrimp culture pond. This study clarifies the effect of one component of the green water culture system, the presence of all male tilapia (Tilapia hornorum) on luminous bacteria Vibrio harveyi. Results showed that stocking tilapia at a biomass not lower than 300 g/m3 efficiently inhibited the growth of luminous bacteria in shrimp (biomass=80 g/m3) rearing water without the growth of microalgae. -

Effect of shrimp biomass and feeding on the anti-Vibrio harveyi activity of Tilapia sp. in a simulated shrimp–tilapia polyculture system
-Aquaculture , 2006 - ElsevierThe efficiency of Tilapia hornorum to control luminous bacteria in a simulated shrimp farm environment has been reported. However, the effects of different factors such as feed input and the shrimp biomass were not taken into consideration. This study investigated the effect of feeding and increased shrimp biomass on the efficiency of tilapia to inhibit the growth of luminous bacteria. Results showed that feeding enhances the antibacterial activity or improves the efficiency of tilapia to inhibit the growth of luminous bacteria. However, the efficiency of tilapia at a biomass of 500 g/m3 is reduced if the shrimp biomass is greater than 80 g/m3. This explains the discrepancies in the results obtained in the use of tilapia to control luminous bacterial disease in shrimp ponds. The effect of starvation on the bacterial load of tilapia, grouper and milkfish feces and the amount of feces in the intestine was also investigated. Results showed that total bacterial and presumptive Vibrio count of fish feces decreased after 1 week of starvation except for the presumptive Vibrio count of grouper. The amount of feces in the intestine also decreased as starvation progressed. Moreover, bacteria isolated from the three species have antibacterial activity against the luminous bacteria Vibrio harveyi. -

On-farm feed management practices for Nile tilapia (Oreochromis niloticus) in the Philippines
- In MR Hasan & MB New (Eds.), On-farm feeding and feed management in aquaculture, 2013 - Food and Agriculture Organization
Series: FAO fisheries and aquaculture technical paper; No. 583The contribution of the Philippines to tilapia production in Asia has increased steadily in the past five years as it addresses hunger and poverty alleviation in the region. Commercial tilapia aquaculture in the Philippines has improved as farmers have become aware of the importance of adopting innovative husbandry technologies. These include the use of intensive culture, using novel feed ingredients, improving the quality of industrial aquafeeds, adopting cost- effective feeding strategies and efficient pond fertilization methods, and culturing improved genetic strains. A case study was conducted to: a) assess current tilapia feed management practices; b) determine recent nutrition-based innovations that include the use of alternative feed ingredients, the adoption of nutritionally complete commercial tilapia feeds, and improvements to feed management practices; and c) evaluate these factors in terms of improved production efficiencies. Thirty-two farmers from selected tilapia cage hatcheries, pond hatcheries, grow- out cages and ponds in Regions III and IV-A (known major tilapia producing regions in the Philippines) were interviewed. The issues addressed included their farm management practices, with particular focus on tilapia feed preferences; quality, procurement and storage methods; and feeding strategies. Their responses were collated and analysed in the context of information simultaneously gathered from the scientific literature, popular publications and relevant websites. The results from the case study highlight the importance of farmers being trained and remaining well-informed about recent improvements in feed technologies and the use of efficient cost-saving feeding strategies to optimize the production of seed and marketable tilapia. Recommendations on how to increase tilapia production through improved feed and feed management practices are described. Finally, recommendations for local regulatory agencies to implement aquafeed quality and nutrient standards are provided.
