Shrimp was fed for 30 days with four different diets: control (0 g kg-1), 5 g kg-1, 10 g kg-1 and 15 g kg-1 seaweed supplemented feed. The seaweed supplementation at the higher concentrations (10 and 15 g kg-1) was found to increase the survival of the shrimp, even though not significantly. The highest total biomass obtained in the shrimp group fed with 15 g kg-1 seaweed diet (P>0.05). Following feeding test, bacterial challenge test using pathogenic V. harveyi was done on the shrimp group previously fed with 15 g kg-1 seaweed diet. The findings showed that seaweed-supplementation significantly increased up to 10% higher shrimp survival after Vibrio challenge. Based on the results of histopathological analysis, hepatopancreas from seaweed-supplemented shrimp showed decreasing tubular epithelial cell lesion by Vibrio infection, suggesting that compounds contained in K. alvarezii by-product meal could have protected shrimp hepatopancreas from distructive effect of Vibrio infection. In general, red seaweed K. alvarezii enrichment on shrimp diet provides protection against V. harveyi infectionduring the shrimp nursery phase.","PeriodicalId":15243,"journal":{"name":"Journal of Aquaculture Research and Development","volume":"31 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80820499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 180 Nile tilapia, O. niloticus, fingerlings (3.78 ± 0.02 g) were assigned to six treatments (three replicates each, 10 fish each), and were stocked in 100 L glass aquarium. Fish were fed with six experimental diets using SBM, CGM, and DDG with or without spirulina supplementation at dose of 0.5%. The feeding experiment lasted for 84 days. The results indicated that tilapia fed on SBM based diet with or without spirulina supplementation have significantly improved growth performance, survival, feed conversion ratio and nutrient utilization compared to other treatments. Serum protein profile showed an increase of significant globulin with SBM and A. platensis supplemented diets. Moreover, the SBM based diet alone or supplemented with A. platensis improved both liver histopathological featuring and glycogen contents, and increased intestinal villi length and area of absorption values.

In Africa, fish culture has grown tremendously due to advances in feed formulation, and the use of better culture facilities such as cages [2]. Even as Asia has become elephantine in aquaculture, Africa as a continent is yet to report any important additions of aquaculture on the world ordered series even though there are many available natural resources in many regions of the continent [3]. Aquaculture continues to grow more rapidly than all other animal producing sectors. According to FAO [4], developing countries‟ contribution by weight increased from 73% in 1979 to 90% in 1998. However, this dramatic increase in production is skewed on a regional basis in favour of Asia. For example, in 1998, aquaculture productions by weight according to the region were as follows: Europe, about 5%; South America, less than 2%; Africa and Oceania, about 0.5% each [5,6]. Moreover, according to FAO (2000), the numbers of fish farmers in the world increased from 7.07 million in 1998 to 7.47million in 2000. The corresponding numbers for 1998 (2000) by region were: Asia, 6.67 (7.13) million; North and Central America, 191,000 (190,000); Africa 56,000 (75,000); South America, 41,000 (41,000) and Oceania 5,000 (5,000). Taken the above into consideration, Africa continues to be a minor player in the global aquaculture industry even though the continent has a natural potential for aquaculture production. Tilapia production which is aboriginal to the African continent has not seen any important growth or development. Nevertheless, according to FAO Africa still has a great potential. For instance, the black tiger shrimp (Penaeus mondon) which is cultured in Madagascar, Eucheuma seaweed in Tanzania and as well as abalone (Haliotis spp) in South Africa [7].","PeriodicalId":15243,"journal":{"name":"Journal of Aquaculture Research and Development","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82875019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Application of enterprise budget for profitability analysis showed that profits for tilapia were significantly different (p ≤ 0.05) between the two countries with Malawi registering a bigger benefit-cost ratio of 1.61 than 1.20 for China. However, 3 farms in Malawi posted losses during the production cycle. Breakeven price was $2.00 for Malawi against $1.26 for China. Sensitivity analysis was conducted to evaluate the influence of changes in price, feed, labour and fixed cost on net profit. Holding all conditions constant, sensitive coefficient for price was relatively high for Malawian farms at 2.63 followed by feed, labour and fixed cost at -0.70, -0.36 and -0.32 respectively. Similarly for China, price showed the highest elasticity of 5.96 compared to -3.65, -0.67, -0.27 of feed, fixed cost and labour respectively. For the farms that did not make profits, application of the shutdown rule indicated that the farms were making surplus gross margins hence could continue operating (Price ≥ Average Variable Cost; and Revenue ≥ Total Variable Cost). The present study has demonstrated that differences in input intensification result in different gross revenues since yield is a function of stocking density, feed input, labour and other production inputs. Irrespective of the intensity of input use, farmers still make profits, thus tilapia production is a viable enterprise in both countries.","PeriodicalId":15243,"journal":{"name":"Journal of Aquaculture Research and Development","volume":"7 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82367311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among protein plant sources, Azolla seems to be good replacer of protein from expensive sources such as fish meal and fish oil depending on feeding habits of the fish species. It contains high crude protein content (13% to 30%) and essential amino acid (EAA) composition (rich in lysine) than most green forage crops and other aquatic macrophytes. A review was conducted on significance of Azolla meal as a protein plant source in finfish culture, mostly focus was on Tilapia species and family Cyprinidae. About 30 published online journal papers, from Research gate and Google scholar in aquaculture nutrition were reviewed. Among reviewed papers revealed that, the dietary Azolla supplementation at certain level have a positive effect on feed utilization and protein conversion ratio, mobilization and utilization of glycogenic amino acids, and growth performance. Therefore, this review suggests that, 10-45% Azolla inclusion level can be incorporated in the diet for Tilapia species, except for T. zillii which requires more than 40% protein contents. While in fish belong to the family Cyprinidae, the inclusion level should be 10-50% for Rohu, and 10-25% for the rest of family members, except Labeo fimbriatus which didn’t shows any effect up to 40% Azolla inclusion level in a diet.","PeriodicalId":15243,"journal":{"name":"Journal of Aquaculture Research and Development","volume":"45 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80763502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
