Fish bombing not only kills the target fish but also destroys nearby small fish and even planktons , thus , destroys the related food chains and cycles of the marine ecosystem . it would take years for the environment and fisheries resources to rehabilitate and , in turn , cause severe impacts to the livelihood of fishermen 炸鱼不但杀死渔民欲捕捉的鱼类，亦会杀害附近的鱼苗和鱼类赖以维生的浮游生物，引致海洋生态系统的循环及食物链遭受到严重的破坏，因此海洋环境及其渔业资源需要多年才能恢复正常，因而严重影响渔民的生计。
" we also propose providing the director of agriculture , fisheries and conservation with powers to enable her to impose a requirement for health or sanitary certification when a genuine risk to public or veterinary health arises from the import of fish , meat , animal fodder or other items used with animals , birds and fish , " dr wong said 我们也建议授权渔农自然护理署署长，使她能施加规定，订明当进口的鱼类、肉类、动物饲料或连同动物、禽鸟和鱼类使用的其他物品，确实会对公众或动物健康带来危害时，该等物品均须附有有效的健康或?生证明书才可进口。
Its gene includes seven exons ( 3 - 9 ) and six introns ( 3 - 8 ) . with respect to zfghrl , it is also like other ghr1s , which consists of 1578bp and encode a 528 amino acid protein . its gene only includes eight exons ( 1 - 5 , 8 ) and seven introns ( l - 5 ) . various methods used to find out the transmembrane and boxl domain of zfghrl but the result turns out to be fruitless due to unknown reason . fghr2 and zfghr2 : fghr2 includes eight exons and seven introns , which consists of 1710 bp and encodes a 569 amino acid protein ; zfghr2 includes eight exons ( 1 - 5 , 8 ) and seven introns ( 1 - 5 ) , which consists of 1758 bp and encodes a 484 amino acid protein 得到的fghr1含有7个外显子( 3 - 9 )和6个内含子( 3 - 8 ) ，由1755个bp的核苷酸组成并编码一个584个氨基酸残基的蛋白质：得到的zfghr1包含有1587个核苷酸并编码一个528个氨基酸残基的蛋白质，理学硕士学位论文:南方贴生长激素受体cdna的分子克隆和鱼类存在两种生长激素受体的证明其基因只有8个外显子( l一5 ， 8 )和7个内含子( 1一5 ) 。
