There have been recent changes in the Caspian Sea ecosystem, such as those due to changes in sea level or those caused by the invasive ctenophore, Mnemiopsis leidyi. It is believed that these changes had significant impacts on the absolute and relative abundance of the commercially important anchovy kilka (Clupeonella engrauliformis) and common kilka (C. cultriventris caspia) leading to decline...

The damaging of the seas is now one of the world's gravest environmental problems, according to a new report by a group of distinguished scientists who have studied one of the world's key fishing grounds: the North East Atlantic. The team travelled around Europe, visited the US and gathered additional evidence from Australia, New Zealand and Japan. Their conclusion is that fishing activity in t...
The main problem with purse seine operations is the erratic line pull time. This greatly affects total catch obtained in each trip. Therefore, this study aims to analyze correlation value of time and catch, then effect between two. research method used experimental fishing for 3 months. implementation was carried out March-June 2020. data analysis analysis, ANOVA regression. (r) pulling 0.72 (s...
Wherever I go in the world today, newspapers invariably contain a story about over fishing. In Australia, it is Patagonian toothfish, abalone and the resources of the Great Barrier Reef. In Asia, shark finning. In the Caribbean, Garoupa s. In the Pacific, Tuna, and in the Atlantic, Cod. To name but a few.

BACKGROUND Illegal, Unreported and Unregulated (IUU) fishing is a problem for marine resource managers, leading to depletion of fish stocks and negative impacts on marine ecosystems. These problems are particularly evident in regions with weak governance. Countries responsible for sustainable natural resource management in the Southern Ocean have actively worked to reduce IUU fishing in the reg...
Identifying the most sensitive indicators to changes in fishing pressure is important for accurately detecting impacts. Biomass is thought to be more sensitive than abundance and length, while the wariness of fishes is emerging as a new metric. Periodically harvested closures (PHCs) that involve the opening and closing of an area to fishing are the most common form of fisheries management in th...
Fisheries statistics are known to be underestimated, since they are mainly based on information about commercial fisheries. However, various types of fishing activities exist and evaluating them is necessary for implementing effective management plans. This paper assesses the characteristics and catches of the French European sea bass recreational fishery along the Atlantic coasts, through the ...
