Synopsis (short abstract) The increase in Thailand's population and the insufficiency of trawl catch in the traditional fisheries in the Gulf of Thailand led to proposals to increase trawl fishing off the Thai and Malaysian Indian Ocean coasts. Thailand bought a vessel to undertake research on catch rates of good and of scrap fish, changes in abundance, distribution of fish at various depths, potential resources, and the relationship between catch and effort. Certain infrastructural lacunae have hitherto hampered the tra wl-fisheries development of Thailand's Indian Ocean coast: rail or road transport, boats, marketing, landing places, and ice or cold-storage facilities. The analysis of catch and the assessment of stock of demersal fish indicates that the level of sustained yield may already have been reached by 1968. If this is so, additional effort will not increase the yield and may actually decrease it and will certainly decrease the catch per effort and hence the profitability. Systematic surveys for catch and effort studies and research on the biology of commercially important demersal fish species should be intensified and carried out regularly to acquire the scientific basis for proper management of fish stocks in the future.

    The Egyptian capture fisheries production from the Mediterranean Sea is showing a decreasing trend that began in 2008 and continued to the present. Most of the production comes from the capture of species in the coastal zone and over the continental shelf. The Egyptian Mediterranean fishing fleet is dominated by trawlers, which represent the backbone of the fleet in terms of both economic value and employment. Trawlers work from fishing ports along the Egyptian Mediterranean coast and are not restricted by geographic boundaries; consequently, the landed fish species cannot be attributed to certain fishing grounds or definite geographic areas. Trawl fisheries are essentially multispecies, targeting shrimps, common cuttlefish and some fish species like Mullus spp., soles, brushtooth lizard fish and species of the family Sparidae. Most of the stock assessments recommend a reduction of fishing mortality by about 40 percent, with the recommendations lower for some fisheries and higher for others. Trawlers mainly sell their production through wholesalers while the small-scale and artisanal vessels channel their production primarily through the fish market. Generally, fishery management in Egypt is challenged by the complex nature of the associated social-ecological systems.
