The first experiment was conducted to determine the effect of maintaining tilapia broodstock in BFT system in terms of reproductive performance and offspring quality as compared with the conventional clear-water system. A total of 45-tilapia broodstock were reared for 2 months in each treatment. Females at advanced maturation were transferred to four spawning tanks (800 L) at a density of eight individuals per tank (3:1 female:male sex ratio). Two tanks were assigned to each of the two treatments (BFT and control). Reproduction took place over the course of 2 months, with all females being inspected weekly to verify the presence of eggs. The second trial (43 days) analyzed the effect of BFT system on growth performance, feed utilization, digestive enzymes activity, and antioxidant status in the early fry stages. A total of 540 larvae (8.7 ± 0.7 mg) were assigned to six glass aquariums (60 L capacity). One experimental group was reared using a BFT system with daily sugar addition at a C/N ratio of 15/1, in comparison to a control group reared in clear water. Fish were fed commercial pellets three times a day at various feeding ratios (6–9% of the fish body weight). The fecundity of tilapia, hatching rate, egg and larval size, and larval resistance to stress tests presented no significant differences among treatments (P > .05). After 20 days of larval rearing, the daily weight gain was 29% higher in BFT fish as compared to the control treatment. The BFT system had better feed conversion ratio than control treatment. The larvae reared in BFT system had significantly higher alpha-amylase and catalase activities than control (P < .05). Overall, these results suggest that the BFT system can be used in tilapia hatcheries for broodstock rearing without negative effects on reproductive performance. The better growth performances of larvae reared in BFT treatment justified the application of this system during nursery phase.KEYWORDS: Nile tilapiabioflocreproductionlarval qualityenzyme activity AcknowledgmentsThe authors would like to thank Ms Ferhane Djamila, the director of the marine fish farming experimental station (Bousmail, Algeria) to facilitate the conduct of experiments.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe author(s) reported that there is no funding associated with the work featured in this article.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":"582 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135814207","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}

It is the state fish of Kerala and very popular in the main tourist destinations/cousins in Kerala. It is mainly collected from brackish water creeks and canals for domestic consumption. However, several environmental and ecological problems lead to the significant reduction of pearlspot in natural water bodies. The promotion of Pearlspot farming is the only sustainable solution for this crisis. Nevertheless, one of the main issues in Pearlspot farming is the lack of quality seeds in sufficient quantities to undertake commercial farming. Massive seed production is the only way to meet the ever-increasing demand for Pearlspot seed. Several attempts to produce Pearlspot seed stock under hatchery conditions have been unsuccessful. The present paper reports the methods to achieve the mass-scale seed production using pond based seed production method. In this, two brackishwater ponds, each with dimensions of 40 m × 50 m × 0.9 m and water access from the creek, were selected. Scientific procedures were followed to produce large Pearlspot seeds throughout the year. The technology ensures the production of 50,000 seeds from a single breeding pond of 0.5-acre area, which can meet the seed requirement for above 3 ha area. The present study proved that Pearlspot reproduction in natural ponds could produce seed stock on a commercial scale.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":"32 1","pages":"1154 - 1161"},"PeriodicalIF":1.2,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324464","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}

An increase in pyruvate kinase (PK, glycolytic enzyme) activity and decrease in glucose-6-phosphate dehydrogenase (G6PD, lipogenic enzyme) activity were noticed with increasing dietary lipid content. A decrease in PK and increase in G6PD activities were observed with increasing dietary protein levels. Activities of the gluconeogenic enzymes (glucose-6-phosphatase, fructose-1,6-phosphatase) increased significantly (P < 0.05) with increasing dietary protein and lipid levels. Amino acid catabolizing enzymes, alanine transaminase and aspartate transaminase, were slightly increased with increasing dietary protein levels.
