The aims of this study were to examine the efficiency of inducing triploid mussels by various treatments and to determine the effect of triploidy on larval development. To produce triploids, extrusion of the second polar body of fertilized eggs was inhibited by 6-(dimethylamino)purine (6-DMAP), cold-shock, or heat-shock treatments. Triploidy was detected by flow cytometry for all the treatments. Treatment with 6-DMAP was the most efficient with a rate of triploidy of 90%, followed by heat-shock (56%) and cold-shock (30%) treatments. No survival differences were observed between diploids and 6-DMAP-induced triploid larvae from the D-shape stage up to their settlement. Moreover, increased growth was observed in triploid larvae compared to diploid larvae. Overall, this study showed that 6-DMAP is a highly efficient method to induce triploidy in mussels, with triploid larvae having faster growth compared to diploid.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47530161","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}

Development rate was also higher in RAT, where 44.3 ± 13.8% of the larvae were able to reach the zoea X stage by the end of the experiment. Among the larvae in AT, 88.5 ± 10.3% of them were at the zoea IX stage and a small percentage of the larvae were still at the zoea VIII stage on day 30.

The experiment was conducted in three replicates, each with 500 liter tanks containing 50,000 larvae (100 larvae/liter), over 40 days and in a completely randomized design. The results showed that the larval metamorphosis and settlement are varied insignificantly with probiotics and significantly with days of application whereas no noticeable changes occur with SKB01 and SKB02. Furthermore, the survival rate decreased slightly with the PLUS10 (11.1 ± 4.2) compared to the control and falling dramatically with SKB01 and SKB02. Additionally, there was a marked improvement in larvae growth with PLUS 10. Finally, Finally, probiotics such as SKB01, SKB02, and PLUS10 enhance water quality, but they have a little negative impact on survival rates at this stage. As a result, it is recommended they can be utilized in the juvenile stage rather than the Auricularia stage.

The purpose of this study thus is to identify the implicit price of the fish quality characteristics. In total, 200 consumers were randomly interviewed from three different coastal districts of Bangladesh where both farmed and wild fish were available. The consumers were interviewed using a semi-structured questionnaire during their purchase and the semi-log functional form of regression model was applied to explore the implicit price of the fish quality characteristics. The findings indicated that consumers’ high payment (at least 61% price premium) on wild fish for its taste, size, and eye character. However, it was found that consumers preferred farmed fish for its freshness and bright color while they disfavored swollen abdomen and odor. The results also revealed that consumers paid 18% more for the farmed fish freshness and 9% less for the fish with odor and swollen abdomen. It was also noticed that quantity of the fish and presence of bones were the influential factors of reducing the price of both fish. The study implies that fish farmers need to produce fish considering quality characteristics rather than producing more since good food ensures good health. The study refers to the implementation of the ‘Government Fishery Act’ for increasing the wild fish stock including different small indigenous species, catfish, and hilsha for consumers’ demands and preferences.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47959534","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}
