“…A variety of fishing gear was used, of which more than one was normally used in the same fishing trip, indicating the multispecific nature of fishing in Amazonia (FREITAS et al, 2002;BATISTA and PETRERE, 2003). However, most of the fish landed was caught with gillnets and redinhas, corroborating the findings of other authors for the Amazon region (BATISTA and PETRERE, 2003).…”

“…The large seasonal fluctuation in water level (> 10 meters) offers dynamic variability in aquatic habitats and fishing grounds. Amazonian fishers' in-depth knowledge of the behavior of commercial species is demonstrated by their use of a wide arsenal of artisanal fishing gear, which varies based on changes in the hydrological cycle and the type of fishing ground being exploited (FREITAS et al, 2002;BATISTA and PETRERE, 2007).…”

The commercial fisheries existent in the sub-basins of the Madeira, Purus, Juruá, high Solimões and low Amazonas rivers was studied, aiming to build an integrated scenario of fishing at the Amazon Basin. The data were collected in 2012 at the main docks in the cities of Humaitá, Boca do Acre, Juruá, Tabatinga and Parintins. The common name of the fish species was registered, along with other information such as catch (kg), fishing gear, origin and fishing effort. In general, migratory Characiformes were the most abundant. Boca do Acre on the Purus River showed a dominance of Siluriformes, mainly surubim (Pseudoplatystoma spp.). In general, fishlandings were higher during the falling water season. Gillnets and a kind of purse seine (locally called "redinha") concentrated the captures and River and lakes were the most explored fishing grounds. The CPUE (catch per unit effort) varied between 12 and 216.5 kg fisher.day -1 , with high averages in the Parintins and Juruá Rivers.

“…Similar to fish caught in other tropical floodplain ecosystems (de Merona 1990; Baran 2005;Freitas et al 2002), fish yield in the studied floodplain ecosystem fluctuated considerably throughout the year. We found that high yields occurred during the rainy season and during the transitional period, from rainy to the dry season.…”

Gumiri S, Ardianor, Syahrinudin, Anshari GZ, Komai Y, Taki K, Tachibana H. 2018. Seasonal yield and composition of aninland artisanal fishery in a humic floodplain ecosystem of Central Kalimantan, Indonesia. Biodiversitas 19: 1181-1185. Seasonal yieldof an inland artisanal fishery was studied in 2015 in the Takapan Floodplain Lake located along the Rungan River of Central KalimantanProvince-Indonesia. Record on daily fish catch consisting weight data and species composition was made in situ along with a one-yearrainfall data that was collected from the nearest Meteorological Station located in Palangka Raya City airport. Results showed thatthroughout the year, total annual yield of captured fishes reached 4.8 tons comprised of 34 commercial freshwater fish species. Seasonalyield varied considerably in which fish capture was higher during the rainy season than on the dry season. The transition period fromrainy to dry season was found to be the peak period of fish capture in the floodplain. Of the 34 fish species, the most abundant specieswas Channa striata that accounted to almost 50% of total annual fish yield. The two most abundant fishes, Channa striata, andKryptopterus palembangensis were a top predatory blackfish and an omnivorous surface water whitefish, respectively. This resultindicated that the studied floodplain habitat was still in good condition, however, conservation is needed to maintain the sustainability offreshwater fish resource in the future.

“…Chavez et al (2002) identified 5 migratory/seasonal species from the 15 species caught in the Bay of Guaratuba (PR). The same seasonal pattern of capture was identified by Freitas et al (2002) in riverine communities in Central Amazon, correlated to environmental factors, and Ramirez et al (2007) described the fish caught by some caiçara (marine coastal settlers) communities in the state of São Paulo. Martins and Perez (2008) identified a remarkable variation in the catches by gillnets and encircling nets in Florianópolis, related to the wind direction and presumably to the thermal structure of the water column.…”

Small-scale fishers use a wide range of gear and fishing techniques, catching large quantities of fish (Salas et al., 2007). The operation of the small-scale fishing fleet is constrained by environmental characteristics and the seasonal behaviour of the exploited resources.In Florianopolis, various types of fishing gear are found, with a predominance of gillnets (anchorage, driftnet, etc.), as well as zangarilho to catch squids and beach seine IntroductionFishing activity may be considered as the combination of different interacting components, including man, natural resources and management systems, influenced by internal and external factors. As such, fishing is composed of a group of interrelated activities, including capture, fish processing, the market and the consumer's demand for fish, operating on certain socioeconomic and political contexts (Salas and Gaertner, 2004 AbstractThe objective of this paper is to describe the main characteristics of small-scale marine fisheries in the municipal district of Florianópolis (SC), the capital city of the state of Santa Catarina. We give information about the most captured species, the fishing fleet and fishing gear used. The dynamics of the activity is described, considering the kind of operation of the boats, alongside post-capture procedures. The analyses were accomplished in two types of fishing communities: the one composed of fishers that fish in bays (North and South) and those who fish in the open sea. Numeric differences were observed among these two fishing areas, indicating the existence of two different fleets operating in the area. Differences between the two fishing areas were detected, considering the species caught, the harvest time and the fishing gear used. The open sea fishers have boats with dimensions, engine power, number of crew and fuel consumption numerically higher than those working in bays, indicating the existence of two distinct fleets operating in the region.Keywords: marine small-scale fisheries, fishing dynamics, fishing gear, harvest season, Florianópolis. Pescarias marinhas de pequena escala no município de Florianópolis, Santa Catarina, Brasil ResumoEste trabalho teve como objetivo caracterizar a pesca de pequena escala no município de Florianópolis (SC). São apresentadas informações sobre as principais espécies capturadas, sobre a frota e artes de pesca utilizadas, sobre a dinâmica da atividade, considerando a forma de operação das unidades produtivas, e sobre os procedimentos pós-captura adotados. As análises foram realizadas em dois tipos de comunidades pesqueiras: as compostas por pescadores que atuam em baías e aquelas cujos integrantes pescam em mar aberto. Foram detectadas diferenças entre as duas áreas de pesca considerando as espécies capturadas, as épocas de captura e as artes de pesca utilizadas. Os pescadores de mar aberto possuem embarcações com dimensões, potência dos motores, número de tripulantes e consumo de combustível numericamente superiores aos que atuam nas baías, indicando a existência de duas frotas dist...
