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%. This could be a way of increasing the income of small producers through the diversification of their production.","PeriodicalId":9062,"journal":{"name":"Boletim do Instituto de Pesca","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135933862","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 study evaluated four treatments (C: without probiotics; T1: 1 × 104 ; T2:1× 106 ; and T3: 1 × 108 CFU·mL-1) in quadruplicates. The larvae (n = 160; weight = 5.3 ± 2.3mg and length = 3.73±0.4mm) were distributed in 16 L containers at a density of 10 larvae·L-1 for 20 days. The productive performance, survival, gut microbiology, and histology were measured. The larvae were also submitted to acute challenge against the pathogenic bacterium Aeromonas hydrophila. The results showed that supplementation with 1 × 108 CFU·mL-1 promotes greater gain in length (13.78 ± 0.40 cm) and total weight (0.08 ± 0.002 g), higher counts of lactic acid bacteria and lower total heterotrophic in the intestines (7.11±0.30; 0.12 ± 0.09 log CFU·g-1, respectively) and larger villi (0.26 ± 0.03μm).

The experiment lasted 120 days, with two treatments, bioflocs (TBio) and aquamimicry (TMi), and three replications for each. In both treatments, the average values of the water quality parameters were as follows: temperature was 24.0 ± 0.32 °C, dissolved oxygen was 8.00 ± 0.45 mg·L-1, pH was 8.40 ± 0.20, and alkalinity was 240.01 ± 37.15 mg·L-1. The control of water quality was effectively maintained in both treatments, indicating the aquamimicry system’s capability to efficiently recycle the nutrients found in the lined ponds’ water. Furthermore, both treatments demonstrated efficiency in shrimp production, and the shrimp from the TMi treatment reached an average final weight of 11.73 ± 2.21 g, average survival of 53.3 ± 15.2%, and productivity of 3.56 ± 0.15-ton·ha-1.

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.
