Abstract:

Effective fisheries management requires an understanding of human dimensions. This study elicited the salient motivations for recreational blue swimmer crab and black bream fishing in Western Australia and whether these views differed depending on the fishing location and/or the characteristics of the fisher. Crab fishers were strongly consumption-orientated and aimed to “catch big crabs” and “catch enough crabs to eat”. Furthermore, 91% consumed their catch, with only 2% practicing catch-and-release fishing. In contrast, 81% of black bream fishers did so for the sport/challenge, with the stro

Abstract:

Abstract Fisher perceptions are a useful source of information that allows changes in stocks to be detected quickly and indicate the social acceptability of different management regulations. Yet traditionally, such information is rarely employed when developing management approaches. Face-to-face interviews were used to elicit recreational and commercial fishers’ perceptions of a crab (Portunus armatus) fishery in three south-western Australian estuaries. Differences in the perceived changes in the average size of crabs and fishing effort, reported concerns and supported solutions were detecte

Abstract:

Illegal fishing in small-scale fisheries is a contentious issue and resists a straightforward interpretation. Particularly, there is little knowledge regarding cooperative interactions between legal and illegal fishers and the potential effects on fisheries arising from these interactions. Taking the Chilean king crab (Lithodes santolla; common name centolla) fishery as a case study, our goal is twofold: (i) to model the effect of illegal-legal fishers’ interactions on the fishery and (ii) analyze how management and social behavior affect fishery’s outcomes. We framed the analysis of this prob

Abstract:

Abstract Considering the blue swimming crab (Portunus pelagicus) was exported as pasteurized crab meat, the quality of fresh meat (stock and size) could have been influenced by the season and needed to be considered. This study aimed to analyse the effect of the season on the crab’s abundance and size in Rembang Water, Central Java. The study period includes four seasons, namely west monsoon, first transition, east monsoon, and second transition from July 2021 to June 2022. The crab samples from the fishermen were analysed in term of the fishing trips, weight, and carapace width at the fishing

The context for this study was to document fishers’ experience-based knowledge is reliable and can be included in citizen science as supplementary information to scientific research. Fishers’ experience-based knowledge contributes to important understanding of the environment and the marine ecosystem. Hence, fishers’ knowledge over time is not always regarded as supplementary knowledge. There is a lack of information on how fishers have acquired reliable knowledge when they have not had formal scientific education and in what way fishers’ knowledge can be used as empirical data.

Abstract:

The use of mosquito nets, primarily for targeting small and/or juvenile fish, has rapidly increased in Western Indian Ocean shallow seagrass beds and coral reefs over the last 20 years. However, to date, invertebrate by-catch by locally-made fishing gear has not been reported. We studied the mosquito net trawl fishery in seagrass areas in the Bay of Toliara, Southwest Madagascar through the GPS tracking of fishers from August 2018 to February 2019. Catches were monitored through monthly landing surveys to characterize spatial temporal patterns in the abundance and diversity of macroinvertebrat

Abstract Mesolithic populations from coastal areas are known as hunter-gatherer-fishers. This way of life is visible in the landscape owing to the presence of large accumulations of shells named shell middens. These anthropogenic refuse heaps are composed of high proportions of marine resources, yet studies dedicated to marine components are relatively recent. Efforts have been made to record marine molluscs, but other minorities are still invisible as a result of the small sizes of archaeological remains. Crustaceans are one of these minorities and this article will focus on one of them: crab

We used measurements of environmental condition, biomass, richness and evenness of its prey as predictors, and modeled the density of O. trimaculatus through a

More than 80% of national fishery production is produced by small-scale fishers, who generally have low levels of education and live in small communities, making them vulnerable to global changes. Fishers in small-scale fisheries use simple technology to limit the search for target commodities and new land. Fishing technology and variability of fish commodities are spatial components that reflect the productivity of fish commodities. In this study, cluster analysis was used to identify shifts in the distribution of marine resource use in 2008-2017 in 34 provinces of Indonesia. By understanding

Abstract Improved fisheries management provides fishers with more opportunities to maximize harvest value by accounting for valuable attributes of the harvest such as species, harvest timing, fish size, product form, and landing location. Harvest values can also vary by vessel and gear type. Moreover, the extent of targeting can influence the ecosystem in which the fishers operate and provide important management challenges. We utilize a unique dataset containing daily vessel-level fish landings in one region of Norway in 2010 to investigate the value of an array of attributes, including speci
