A total of 1951 species of freshwater and marine fishes belonging to 704 genera and 186 families are recorded in Malaysia. Almost half (48%) are currently threatened to some degree, while nearly one third (27%) mostly from the marine and coral habitats require urgent scientific studies to evaluate their status. Freshwater habitats encompass the highest percentage of threatened fish species (87%...
Across all major industrial fishing sectors, overfishing due to overcapacity and lack of compliance in fishery governance has led to a decline in biomass of many global fish stocks. Overfishing threatens ocean biodiversity, global food security, and the livelihoods of law abiding fishermen. To address this issue, Global Fishing Watch (GFW) was created to bring transparency to global fisheries u...
O environmental degradation, and redistribution of surface water have placed great stress on inland fisheries throughout the world. Human activities usually shift the balance among fish species, causing the extirpation of many indigenous species and the dominance of a reduced set of often introduced fish species. The result has been a massive reshaping of fish communities in the world’s fresh w...
Understanding overfishing and regulating fishing quotas is a major global challenge for the 21st Century both in terms of providing food for humankind and to preserve the oceans' ecosystems. However, fishing is a complex economic activity, affected not just by overfishing but also by such factors as pollution, technology, financial factors and more. For this reason, it is often difficult to sta...
Using global fishery outputs from 62 countries during the period 2001–2020, this study applies threshold panel data model of Hansen (2000) to empirically explore nonlinear relations between number fishing vessels, fishers, and production, with distinct overfishing stocks (overfishing) fish caught by trawling or dredging techniques (trawling) as variables. Our findings show that levels could be ...
A new study has shown that maximum overfishing of coral reefs occurs among countries at intermediate levels of socio-economic development; can managers and policy makers help countries dependent on these ecosystems avoid the resulting poverty traps?
