The eco-friendly fishing gears (EFFGs) have been widely suggested as fishing gears for sustainable blue economy development. This study aims to examine the effects of the utilization of the EFFGs of blue swimming crab (BSC) on fishermen's welfare and sustainable fisheries by taking Indonesia as a case study. The number of fishermen randomly sampled was 647.

Blooms of Chattonella with fisheries damage have been recorded in East Asia since 1969, whereas they have been only recorded in Southeast Asia since the 1980s. Occurrences of Chattonella have been documented from six Southeast Asian countries, Indonesia, Malaysia, Philippines, Singapore, Thailand and Viet Nam, with mass mortalities mainly of farmed shrimp in 1980-1990s, and farmed fish in 2000-2010s.

Using a digital data collection system (OurFish), that records purchases by fish traders from small-scale fishers, data was collected across 82 coastal communities in Southeast Sulawesi. We found that the number of active fishers and traders declined by more than 90% after the onset of the pandemic and the average weight of catch per fishing trip increased across fishers.

- - The unarmored dinoflagellate suspected to cause harmful algal blooms in Lampung Bay, Indonesia, has been linked to significant fish deaths since 2012.
- - A study analyzed sediment samples and found high concentrations of resting cysts of this dinoflagellate on the northern coast, with counts ranging from 20.6 to 645.6 cysts per gram of sediment.
- - Molecular analysis identified different ribotypes of the species, confirming its prevalence in both vegetative and cyst forms in the area.
Article Synopsis
- The biggest hurdle for global fisheries recovery is the need to cut fishing efforts and profits in the short term, which many countries are reluctant to do due to political and social pressures.
- By focusing on eliminating illegal, unreported, and unregulated (IUU) fishing, nations can effectively recover their fisheries without these immediate costs.
- For example, Indonesia's strict measures against IUU fishing led to a 25% reduction in fishing effort, resulting in potential increases in both fish catch and profits, showing that reform is possible without hurting local economies.
The present study reports concentrations of polybrominated diphenyl ethers (PBDEs) and organochlorines (OCs) in human breast milk from Indonesia covering urban, suburban and rural areas. PBDEs were detected in all the samples of the present study with total concentrations ranging from 0.49 to 13 ng/g lipid wt.

PCBs and DDTs were the predominant contaminants with concentrations from 9.7 to 2700 ng/g lipid wt.
