Global seafood demand has continued to rise amidst challenges to traditional aquaculture operations.Current shrimp aquaculture practice requires high water exchange and discharges toxic effluent to the environment.Biofloc technology(BFT)is self-sustaining and emphasizes nutrient cycling through microbial activity to maintain water quality.The effect of BFT on water quality and profitability of shrimp(Litopenaeus vannamei)culture was determined over a 70-day period.Ponds P1,P2,and P3 were treated with BFT and compared to a control group(P4)without BFT.Bacillus infantis cultured inoculum initiated biofloc development while molasses-maintained C:N ratio of 15:1.One-way ANOVA determined the mean differences in Temperature,pH,dissolved oxygen(DO),total dissolved solid,alkalinity,salinity,ammonia(NH3),nitrates,nitrites(NO2-),calcium,magnesium,as well as shrimp body weight(BW)and total length(TL)across treatments.Profitability was determined by comparing the cost of production with sales and plotting it on a bar chart.BFT shrimp exhibited significantly higher BW(13.6 g)compared to 8.1 g in the control,and maintained a higher survival rate(80–90%)by day 70.Water quality was better managed in BFT,with NH3 consistently kept below 0.5mg/L;transient peaks of NO2-,more stable pH(averaging at 7.5),and better DO management,maintained above 5 mg/L.BFT provided higher profitability of Ringgit Malaysia(RM)11,019.67(P1)and RM 8651.83(P2)compared to financiallosses in the non-biofloc system.Although operational challenges were reported,BFT showed superior resilience,suggesting that proper technical training and farm management are crucial for its optimization. 展开更多

Common collagen extraction methods are outdated and unsustainable.This study introduces a more sustainable method using water extract from banana peel to extract collagen from sardine bone,a prevalent marine fish in Malaysia.Banana peel was chosen as the feedstock for solvent preparation due to its abundance and agricultural significance in Malaysia.This study examined how extraction parameters including temperature(27−43℃),sardine bone-to-solvent ratio(1:15−1:28),and extraction time(8−88 h)affect the collagen extraction yield.FT-IR,TGA,and proximate analysis were used to characterize the collagen extracted,while the water extracts were analyzed using UV-Vis and GC-MS.Under optimum conditions of 40℃,a sardine bone-to-solvent ratio of 1:24,and an extraction time of 74 h,yielded 9.82%collagen.When citric acid was used as the common solvent,the collagen extracted yield was 4.06%.Further investigation of water extracts from other fruit waste sources,including mango peel,coconut husk,and pineapple pomace,under optimum conditions,obtained an extraction yield of 11.79%,2.10%,and 13.58%,respectively.This study demonstrated the use of fruit waste extract as an environmentally sustainable method for extracting collagen from marine fish,highlighting an efficient approach to waste valorization. 展开更多

Recirculating Aquaculture System(RAS)is introduced in aquaculture farming industry to reduce water resource utilization,efficient the energy and land uses,and also help minimalize the water exchange.This system enables utilization of unsuitable land and promotes a sustainable environment in aquaculture industry.Furthermore,this technology has been established and proved efficient in monitoring the aquatic animal condition subsequently helps in maintaining the water quality and help remove solid particle wastes from the aquaculture treatment.As today,RAS has been developed with more effective technologies such as the use of UV irradiation,solid capture,protein skimmer and also provided with highly techno bio-filtration set.Basically,this system was applied for broodstock maturation,nursery phase,and grow-out production.In this review article,we provide an overview of RAS between the clear water,probiotic,and biofloc technology,and the advantages of its combination.Even though RAS and biofloc is two different parallel system,the application of the probiotic and biofloc in the semi-RAS application system is intense to be investigated.The synergistic effect of RAS using this combination towards high yield aquaculture production will be highlighted in this review paper.Expectantly this review paper will generate awareness and useful information on the RAS application in the aquaculture system operation with help in maximize the impact to the aquaculture yield production. 展开更多
