虾类养殖
商业海虾养殖场开始于20世纪70年代,饲养海虾以供人食用。海虾生产量急剧增长以满足市场的需求──尤其是美国、日本和西欧的市场。在2003年,全球生产的养殖虾超过160万吨,价值近九十亿美元。约75%养殖虾由亚洲国家生产,中国和泰国是最大的生产国。其余25%由拉丁美洲国家生产,巴西是最大的生产国。最大的出口国是泰国。
历史和地理
数百年来,亚洲使用传统的低密度方法养虾;印尼的咸水池塘可以追溯至十五世纪。有些小规模渔塘只单独养虾,有一些则连同其他物种,如虱目鱼一起饲养。有些虾则养在旱季的稻田里,与水稻轮作──因为旱季不能种植稻米[1]。传统的小规模养殖场,多数在沿岸地区或河滨。因为红树林地区有丰富的野生虾,所以是最理想的养虾场。野生虾苖被困在渔塘,以天然的水中生物为生,当长到理想的大小时,虾农捞捕虾获。
工业虾养殖的起源,可追溯到20世纪30年代,当时日本首次培育日本对虾(Penaeus japonicus)。到了60年代,日本已经出现小规模的虾养殖业[2]。商业养虾业开始于20世纪60年代末和70年代初。由于技术进步,养虾密度得以增加;另一面,市场对虾的需求日益增长,导致虾养殖场遍布世界各地。虾养殖场主要集中在热带和亚热带地区。1980年代初期,海虾的需求日益增长,与此同时,野生虾渔获郤不能增加,这为海虾养殖业创造一个理想的发展环境,造就它的繁荣。
台湾是其中一个早期的参与者,在上世纪80年代是主要的养虾生产地。然而由于管理不善和疾病,台湾的虾养殖工业从1988年开始崩塌[3]。从1985年开始,大型的高密度虾养殖场在泰国迅速扩展[4]。厄瓜多尔率先在南美开发养虾业,并且从1978年开始急剧发展[5]。 自1974年以来,巴西的养虾业一直活跃,但是虾贸易到了20世纪90年代,才真正蓬勃发展,令到该国在数年之内,成为主要养虾生产国[6]。到了今天,拥有海虾养殖场的国家多达50多个。
养殖方法
在1970年代,野生海虾捕捞业能供应的海虾产量,不足以满足消费者对海虾的需求,因此海虾养殖成为一个经济上可行的替代方法,以满足市场日益增长的需求。旧式的自给自足的养殖方法(又称少有余粮的农场经营、糊口农业),迅速被淘汰,取而代之的是以出口为主的高密度养虾工业。工业养虾最初仍沿用传统的养殖方法,不过工业养虾场的面积比旧式养虾鱼塘大得多,以弥补低密度海虾的单位面积产量。旧式养虾鱼塘一般只有几公顷大,而在一些地方的工业养虾场的大小,却能达100公顷(1平方公里)。
