摘要

对2017 - 2020年迪尔卡尔省内陆渔业资源现状进行了调查。在研究期间,使用围网、刺网、撒网和电动渔具,从5个湿地捕获的鱼总量约为30833吨。年最高捕鱼量为8502吨,占总捕鱼量的27.6%。事实上,每年鱼类资源的变化可能与过度捕捞、天气变化、污染程度、水位、市场价格和环境条件(自然或人为)有关。这项研究还表明,上岸的鱼大部分来自捕捞渔业,其余来自养鱼业。共捕获鱼类11种,鲤科鱼(Cyprinus carpio)占优势,占总重量的37%,其次是拟螺(Planiliza abu),占总重量的25%左右。其中,本地种6种,外来种2种,迁徙种2种,分别占总数的41.3%、56.5%和2.2%。

The status of Inland Fishery in Dhi Qar Province during the period from 2017 to 2020
An investigation was carried out to overview the status of the inland fishery resources in Dhi Qar Province during the period from 2017 to 2020. The whole fish landed from five marshes throughout the study period was about 30833 tons using seine net, gill net, cast net and electro-fishing gears. The highest annual quantity landed was about 8502 tons in 2020 which formed about 27.6 % of total fish landed. In fact, this variation in fish stock from year to year could be related to overfishing, weather changes, pollution levels, water levels, market prices and environmental conditions (natural or human-made). This study also indicated that the majority of fish landed came from capture fisheries and the rest from fish farming. Eleven fish species were observed and Cyprinus carpio was dominant with 37 % of the total weight landed followed by Planiliza abu which comprised about 25% of the total. Six native species, two alien species and two migratory species were also found throughout this investigation which composed about 41.3 %, 56.5 % and 2.2 % of the total, respectively.
