“…The net linked based on the principle of capital accumulation and efficient market procedures positioned as priority. Somehow, the fishermen were not affected by rapid economic growth of the city (Mendo et al, 2023). Petty producers would only exist when they were accumulated, while the middlemen controlled the whole process.…”

“…Most fisheries management studies have paid more attention to analyzing resources dynamic than exploring the dynamic and social articulations that being utilized by producers (Kuo H, Fu Y, 2021). Some global-scale non-government organizations also indicate their works to emphasize the importance of socio-economic justice for petty producers in the fishing sector, as well as the balance condition of environmental sustainability (Mendo et al 2023). Globalization had brought significant changes in managing the resources (Casola et al, 2021) and its impact has been observed that be created by an ill-adapted fisheries system (Kusuma Mustika et al, 2021).…”

Fishing activities along the coastal areas of Makassar City are influenced by the type of technology used and also the social structures of production process that involved key players, such as wholesalers, exporters, and small-scale fishermen. This article aims (1) to explain the trajectory of fishing development of Makassar City and its impact to the creation of social stratification and (2) to analyze the economic factors that influenced the decision-making processes among producers, especially related to its impact towards small-scale fishermen. Data and information were obtained based on interview and field observation that had been conducted in three fishing communities in the City of Makassar, between September 2019 and January 2020. It is found that globalization impacted the issue of underdevelopment of the small-scale production among poor fishermen; which also indicates the powerlessness concerning the possession of high capacity harvesting equipment commonly owned by the capitalist producers. Social stratifications that were formed among fishermen had placed the small-scale fishermen at the lower level, while the middlemen who have control over capital also have access to the marketing networks and opportunities, thus placing their position at a higher level.

Shrimp trawl fishery is of significant importance in Saudi Arabia’s marine capture fishery sector. Al Qunfudhah and Jizan are the only ports along the southern Saudi Arabian coast of the Red Sea dedicated to shrimp fishing. This study evaluates the catch per unit effort (CPUE) of targeted shrimp species along with the associated retained bycatch and discard ratios across these two trawling locations. Using daily catch data from commercial shrimp trawlers specific to each port’s vessel type, this research provides the first comprehensive analysis of CPUE dynamics and fishing practices in these fishing grounds. The CPUE of target shrimps exhibited a wide range (0.01 kg h−1 to 13.08 kg h−1) with an overall mean of 1.37 ± 0.143 kg h−1. Penaeus semisulcatus emerged as the predominant species (mean CPUE: 3.77 ± 0.28 kg h−1), followed by Metapenaeus monoceros (mean CPUE: 0.1 ± 0.02 kg h−1). Significant differences in CPUE were observed among species, including P. semisulcatus, Penaeus hathor, and Penaeus pulchricaudatus, although CPUE differences between the two fishing grounds were minor, likely due to their proximity and similar environmental conditions. The bycatch analysis identified a total of 72 species across 28 families, with significant variation in the relative ratios. Sepiidae species constituted 31.8% of the total bycatch, followed by Portunidae species (24.8%). Discard patterns also varied, with Gerres oyena being the most commonly discarded species (mean discard ratio: 11.37% ± 1.89%), followed by Equulites klunzingeri (mean discard ratio: 8.76% ± 2.00%). While CPUE differences between Al Qunfudhah and Jizan were modest, this study highlights the need for expanded spatial and temporal coverage to enhance future analyses. These findings underscore the importance of integrated data for a comprehensive understanding of fishing effort and bycatch dynamics, supporting sustainable fisheries management in the Red Sea. By addressing bycatch and discard practices, this research contributes to efforts to mitigate ecological impacts and promote sustainable resource use in Saudi Arabia’s fisheries sector.
