以色列位于中东,地中海的东部,面积约20,700平方公里,境内的内格夫沙漠占了全国面积的一半,因此土地面积狭小。加上这里气候干旱,雨量稀少(南方的年降雨量只有25毫米左右),自然条件对开展水产养殖极为不利。但是政府对水产养殖业却相当重视,他们把建立水产养殖场与扩大农田灌溉面积,提高肉食品供应水平的目的结合起来,充分利用有限的水资源。这种精神是十分可取的。目前,以色列年人均食鱼水平大约在10公斤左右,其中40%是由池塘养殖提供的。养殖品种主要是鲤鱼,罗非鱼、鲢鱼和鲻鱼等。为了提高养殖
Israel is located in the Middle East, the eastern part of the Mediterranean Sea, covering an area of about 20,700 square kilometers. The Negev Desert in the territory accounts for half of the national area. As a result, the land area is small. Coupled with the arid climate here, scarce rainfall (the annual rainfall in the south is only about 25 mm), the natural conditions of aquaculture is extremely unfavorable. However, the government attaches great importance to the aquaculture industry. They combine the establishment of aquaculture farms with the purpose of expanding irrigated farmland and raising the level of supply of meat products, and make full use of the limited water resources. This spirit is very desirable. At present, Israel’s per capita fish consumption is about 10 kg per capita, of which 40% is provided by pond aquaculture. Breeding breeds are mainly carp, tilapia, silver carp and bighead carp. In order to improve farming
