越南今年的气候变化总的来说对农业产品影响大，特别是巴沙鱼的养殖和加工面临诸多困难。阴晴不定的天气导致鱼塘里的巴沙更容易生病，增加养殖成本，显著降低利润。

Climate change ismaking the agricultural production sector in general, raising and processingcatfish in particular facing many difficulties. Unpredictable weather causesthe fish in the ponds to be more susceptible to disease, increased productioncosts, reduced profits significantly.

安江省的巴沙鱼养殖户TRAN VAN NAM先生表示：“春节前，产苗率非常低，从鱼苗到鱼种培育阶段，成活率受天气的影响也非常大，忽冷忽热的天气导致池塘水温不稳定，酸碱度也忽上忽下，是巴沙鱼难以调节适应，跟不上水环境的变化，这样鱼病也趁虚而入，过去，肾脏、肝脏方面的鱼病通常在雨季，在换新水的时候会出现，现在全年都有，导致养殖成本增加。在巴沙鱼塘，塘水的平均酸碱度是7.5-8.5，到现在气温高的时段，不正常的天气，酸碱度有时会上到9.5又突然下降到6.5以下，巴沙鱼难以适应，导致不进食”。NAM先生继续表示：“反常天气，鱼苗不是加工出口商损失的原因，目前，除了特别培育条件外，巴沙养殖都受到严重影响”。

Mr. Tran Van Nam, oneof the Pangasius farmers in Vinh Hoa commune, Tan Chau commune, An Giangprovince, said that before the Lunar New Year, His breeding rate is very low.The stage of rearing from fry to fingerlings, from fingerlings to fingerlingsis strongly influenced by climate change. The "hot, cold" weatherduring the day caused the water temperature in the pond to change suddenly, thePH when rising, when falling down to make the fish adapt to not catch up, fromwhich the fish is weak, fluid The disease is very easy to attack. "In thepast, kidney and liver disease has appeared in the rainy season, the month ofwater pouring, now the disease occurs year-round, which in turn causes the costof raising high. For Pangasius ponds, average pH in ponds is 75-85o. Now, hotweather, unusual temperature, pH in the pond (in one day) sometimes up to 95oand down to 65o, fish in shock so easy to attack fish do not eat, "Mr Namshared. Adverse weather, fingerlings are not the cause of the loss of catfishexporters. Currently, in addition to the specialized nursery fish, fish farmingis heavily affected.

特别是从春节前到现在，养殖户LE THI LAN投入了大量资金来治疗鱼病。上次起捕，LAN一家销售原料巴沙鱼的价格是每公斤30000越盾，但是仍然亏本。“对巴沙鱼塘，当气候变化导致鱼病发生的时候，养殖花费成本会额外增加每公斤3000-4000越盾。饲料成本也上升，饵料系数会从1.55公斤饲料养一公斤鱼，增加到2-2.5公斤饲料养一公斤。如果巴沙鱼生长正常，15.5吨饲料可以收获10吨成鱼，如果鱼生病，15.5吨饲料仅能产出7-8吨成鱼，肯定损失”。安福省的TRUONG VAN VINH先生说道。

Specifically, beforethe Lunar New Year until now, catfish fillet of the family Le Thi Lan (Hoa Lac,Phu Tan) has to spend a lot of money to treat fish diseases. Last harvest,although the price of pangasius meat is 30,000 VND / kg but Lan still sufferlosses. " For catfish ponds, when weather changes lead to disease, thecost of treatment increased from 3,000 to 4,000 VND / kg. The amount of foodincreased, instead of 1.55 foods for 1kg of fish weight gain, now the rate canincrease to 2-2.5 food. "If the fish grow normally, then 15.5 tons offood will produce 10 tons of fish. When the fish is sick, 15.5 tons of food canonly be harvested 7-8 tons of fish or less, losses are certain,"- said Truong Van Vinh (Da Phuoc commune, An Phu) shared.

“除了鱼病，饲料成本也在上涨。巴沙养殖饲料占70%成本。往年鱼卖不出价的时候，饲料成本也没有增加。但是现在，鱼价在最高位，FDI饲料公司，也提高了巴沙鱼饲料的售价。蛋白质含量40%的饲料提价到每公斤17900越盾。一包25公斤的饲料，养殖户要支付447500越盾。这还是一级经销商的价格，在商店里的零售价则更高”。

In addition toattacking diseases, the cost of food. This cost accounts for about 70% of thecapital. The year of fish devaluation, the cost of food for a fish crop doesnot increase. Now, fish prices are at the peak, the FDI enterprises,specializing in providing food to the market has adjusted the price of foodincreased. Specifically, for Greefish food (type 40 protein), up to 17,900 VND/ kg. A 25kg bag of food, fishermen pay 447,500 VND. This is the price of thedealer level 1, and the retail purchase in the store is higher.

今年气候变化对安江省乃至湄公河流域的巴沙养殖、加工、出口都造成不利影响。为了产业链稳定，巴沙养殖户也在调整解决方案，来预先稳定巴沙养殖和加工产业。

Climate change hashad a great impact on the farming and processing of export tra fish in An Giangin particular and the Mekong Delta in general. In order to produce stabledevelopment, fishermen need to calculate solutions to adapt. This is aprerequisite for catfish farming and processing to develop sustainably.
