Abstract
Aquatic germplasm resources are important for conserving biodiversity and supplying material for fishery development.Establishing reserves is one of the major efforts to strengthen conservation and make rational use of a-quatic germplasm resources.From 2007 to 201 4,62 national aquatic germplasm reserves were established in Hubei province.In this paper,the water type,main species protected and geographical distribution of the aquatic germ plasm reserves are analyzed,the major problems in setting up aquatic germplasm resources are discussed and rec-ommendations are made for future construction and management of aquatic germplasm reserves.The 62 national a-quatic germplasm reserves consist of 31 lake reserves (94 1 23 hm2 ),1 8 river reserves (66 229 hm2 )and 1 3 reser-voir reserves (41 634 hm2 ).The lake reserves are located primarily in Jingzhou,Xiaogan and Huanggang;river reserves primarily in Xiaogan,Shiyan and Yichang,and reservoir reserves primarily in Shiyan,Huanggang and Suizhou.A total of 75 protected aquatic species are listed in the 62 national aquatic germplasm reserves:55 fish, 2 crustaceans,5 mollusks,2 amphibians,2 reptiles and 9 plants.The following general problems occurred during the construction and management of the reserves:1 )lack of development planning,such as the same protected species listed in several reserves;2)lack of funds to support reserve management;3)lack of systematic investiga-tion of water environment and biological resources that restricts reserve development;4)the conflict between re-source usage and resource conservation.Based on the challenges listed above,we suggest the following:1 )develop a comprehensive plan for aquatic germplasm reserve construction in Hubei Province;2)ensure funding for the con-struction of reserves,especially for reserves with abundant resources and rare or endangered species;3)strengthen the management of the aquatic germplasm reserves by declaring the need to consider the geographical distribution of the protected species and assessing the suitability of reserves based on a systematic investigation of the water envi-ronment and aquatic biological resources,that includes habitat needs for the entire life history of protected species.关键词
