“…The preference of riverine communities for consumption of species of this order has already been observed in other studies (Garcez et al, 2009;Silva et al, 2017;Begossi et al, 2019). Characiformes are also the most exploited species by commercial fishing and the most consumed in regional urban centers such as Manaus (Freitas and Rivas, 2006;Corrêa et al, 2014;Faria Junior and Batista, 2019).…”

The consumption of fish by the riverine population of the lower Solimões River, Amazonas, Brazil

et al. 2023

The riverine population of the Amazon Basin are among the largest consumers of fish in the world, but the consumption patterns could be regionally distinct. Moreover, their total fish catches are not fully known. The objective of this work was to estimate the per capita fish consumption of the riverine people that inhabit the Paciência Island (Iranduba, Amazonas), where there is a fishing agreement in force. A total of 273 questionnaires were applied during the first two weeks of each month between April 2021 and March 2022. The sample unit was the residences. The questionnaire contained questions about the species captured and their quantities. Consumption was calculated by dividing the average monthly capture with the average number of residents per household interviewed, which was multiplied by the number of questionnaires applied. Thirty groups of consumed fish species belonging to 17 families and 5 orders were recorded. The total catch was 3,388.35 kg and the highest monthly catch was 602.60 kg during the falling-water season in October. Daily per capita fish consumption averaged 66.13 ± 29.21 g/day, with a peak of 116.45 g/day during the falling-water season in August. The high fish consumption rate highlighted the importance of fisheries management to food security and the maintenance of the community’s lifestyle.

“…Other studies also indicated the variability of landings according to river regime (Isaac et al, 2015;Sousa et al 2017;Lopes and Freitas, 2018). The peacock bass is among the main species landed, not only in the present study area (Faria Junior and Batista, 2019), but also in other regions (Silva et al, 2017) and in reservoirs where it was introduced (Agostinho et al 2007;Novaes et al, 2015).…”

This study analysed the commercial fishing for peacock bass (Cichla spp.) and its variation according to the river regime and the fishing environments, based on landing data in Manaus. The landing data were provided by the Z-12 Fishermen's Association and the monthly quotas (m) of Rio Negro by the National Water Agency, corresponding to the years 2012 and 2013. The Catch per Unit of Effort (CPUE) was obtained by dividing the total catch and the number of boats. A Generalized Linear Model was used to analyse the relationship between CPUE and the river level. Through the Analysis of Variance we compared the averages of capture between the fishing areas and Fisher's LSD test revealed which environments had different capture averages. Student's t-test was used to compare the mean of capture between white and black water environments. The largest catches and CPUEs occurred during receding water, and the relationship between CPUE and river level was inverse. Black water environments obtained the highest CPUEs, as well as the highest capture averages. There were differences in the average catches between fishing areas, but not between water types. This study shows how peacock bass exploitation occurs and can assist in management measures for this species.

“…The greater number of fishing sites and the greater radius of action of the fishing fleet observed in the lower Amazon River in both hydrological periods is probably related to the size of the cities that were analyzed, the characteristics of the vessels used and a higher level of exploitation of the species in the environments near each urban center (Tregidgo et al, 2017;Faria Junior and Batista, 2019;IBGE, 2021). Parintins, in the lower Amazon River, is the municipality with the largest population (116,439) in relation to Tabatinga (68,502 people) and Benjamin Constant (44,873) in the upper Solimões River and Iranduba (49,718) in the lower Solimões River, and demanded a greater landing (IBGE, 2021).…”

In addition, the municipality of Parintins has the second largest number of fishing boats, which have greater storage and transport capacity than other vessels, and which consequently allow fishers to travel greater distances (Faria Junior and Batista, 2019). Keppeler et al (2018), when evaluating indicators of Amazonian fish communities, identified that the distance from the lake to the urban center was positively related to the average size of fish and the dominance of large fish, thus indicating direct human effects caused by fishing or indirect effects by habitat alteration.…”

Spatial dynamics of Amazonian commercial fisheries: an analysis of landscape composition and fish landings

2023

View full text Add to dashboard Cite

Amazonian commercial fishing is artisanal, and landings can be influenced by the flood pulse, the consumer market, the level of exploitation of species, habitat quality and vegetation cover. In this study, landscape variables and the river level were evaluated as possible drivers in the composition of catches landed in three regions of the Solimões-Amazon River. Fish landing data were collected in the upper and lower Solimões River and lower Amazon River. Fishing locations were mapped with information from fishers, civil defense departments and from the literature. Information related to river level and landscape was acquired from databases available online. Maps with the the radius of action of the fishing fleet and the quantification of landscape variables were made for periods of high and low-water, and non-metric multidimensional scaling analysis (nMDS) with catches by species, by region and hydrological period were performed. The largest operating radius of the fishing fleet was of 1,028 km and was identified in the lower Amazon River, which is probably due to the larger size of the consumer market, vessel characteristics and level of exploitation of the species near the landing center. The proportion of vegetation cover was reduced from 87% in the upper stretches of the Solimões River to 46% in the lower stretches. The upper and lower Solimões River regions presented a greater variety of species in the composition of landings. It was identified that the composition of landings between the three analyzed regions possibly varied according to the availability of habitats, indicating the importance of landscape variables for fish landings.
