The study evaluated the effect of nylon net packing on the survival and shelf life of Perna perna mussels farmed in Brazil. Thirty samples containing 10 or 11 market-size mussels were stored in an incubator at 4°C for four days, half packed with nylon netting and the other half maintained within opened containers. The experiment analyzed the following parameters daily: survivorship, intervalvar fluid loss, total volatile bases, pH, and mesophilic and psychrotrophic bacteria counts. By the end of the assay, chemical and microbiological parameters were all acceptable for human consumption. All packed mussels survived up to the second day of storage, while the control group recorded an average survival of 29.7% in the same period. Packed mussels survive longer, probably because the tight net prevents animals from losing liquid by maintaining their shell valves closed during storage. This packaging method extends the shelf life of live products and improves the potential trading live mussels to consumer centers far from marine farms.","PeriodicalId":9062,"journal":{"name":"Boletim do Instituto de Pesca","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135192316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to perform an economic evaluation of the production of A. gigas on earth ponds in San Martin, Peru. Three hundred young fish (19 ± 0.01 cm and 68.32 ± 0.01 g) were stocked (ten fish·m–2 in three ponds of 1000 m2 for 390 days). Growth performance was evaluated based on the survival, feed conversion rate (FCR), final mean weight, final average length, weight gain, specific growth rate, and productivity. Investment, costs, indicators, and feasibility were determined. Arapaima gigas has a profitable production performance in earth ponds in Peru, fish presented a weight gain (kg) of 11 kg in 390 days and productivity of 3,265.70 kg·ha–1. Food and fingerlings were the most important items in the production cost. This production is a low-investment and high-profitable business, with an incremental investment of US$3,287.15, profit of US$ 3,977.38·cycle–1, Net Present Value of US$ 22,149.37, and an Intern Rate Return of 32.28%.

Additionally, in order to create a list of the species of interest of sport fishers, the survey of 22 papers was carried out regarding the species caught. A total of 70 complete papers published between 1994 and 2021 were included in the study. Since the 1990s, publications have increased quantitatively, with most studies coming from the South-Eastern region of Brazil (39.19%). The papers published discussed, in the majority, the sport fishing carried out in marine environment (55.38%), and the focus was “fishing and fishers” (30%). Evaluating the sustainability tripod, most of the papers provided only information regarding the ecological aspect (58.57%). About 330 species of marine and freshwater fish of interest to sport fishers were dealt with in the studies. This information reflects the current state of knowledge about Brazilian sport fishing, and it can serve as a basis for the management of the activity and the target species used by fishers.
