Description

说明书 发明名称:一种长茎葡萄蕨藻养殖池及其养殖方法 技术领域
[0001] 本发明属于水产养殖技术领域, 涉及一种长茎葡萄蕨藻养殖池及养殖方法。
背景技术
[0002] 长茎葡萄蕨藻是隶属绿藻门蕨藻科的一种营养丰富的食用绿藻, 以冲绳为北线 自然生长于太平洋的帛琉群岛、 吉格波特群岛等领域。 由于长茎葡萄蕨藻形状 晶莹饱满似葡萄, 故被称为海葡萄, 因其富含海藻多糖、 胶原蛋白和膳食纤维 , 氨基酸组成均衡且种类齐全, 脂肪含量较低且多为不饱和脂肪酸, 矿物质和 维生素含量丰富, 食用口感如鱼子般丰富多汁, 又有"绿色鱼子酱"之称。
[0003] 由于长茎葡萄蕨藻丰富的营养和优良的适口性, 市场对这种藻类需求快速增加 , 价格极高, 但因大量滥采, 海湾环境变差等因素, 年采收量急剧减少。 为了 增加资源, 1978~1986年期间, 冲绳人在那霸湾幵展人工养殖实验并获得成功。 近年来, 在我国也有零星幵展长茎葡萄蕨藻人工养殖成功的报道, 但规模都远 远达不到产业化水平。 目前, 国内幵展长茎葡萄蕨藻养殖均为静止水、 定期添 加人工营养盐的养殖模式, 养殖成本高, 且无法模拟长茎葡萄蕨藻自然生长环 境条件下洋流流动以及稳定的营养供应, 养殖效果不佳, 养殖效益不高。
[0004] 虾、 鱼养殖是我国海水养殖的支柱产业。 在陆基海水养殖中, 养殖水体中过量 的氮、 磷富集, 尤其是氨氮和亚硝氮累积常导致虾、 鱼中毒死亡, 是导致养殖 失败的主因, 养殖废水的排放也是海域海水富营养化的主要污染源之一。 长茎 葡萄蕨藻具有较强的氮、 磷吸收能力, 且长茎葡萄蕨藻适合陆基养殖, 通过长 茎葡萄蕨藻吸收鱼虾养殖废水中富集的氮、 磷, 一方面废水中富集的氮、 磷为 长茎葡萄蕨藻的生长提供了充足的营养, 避免了人工营养盐的使用, 降低了长 茎葡萄蕨藻的养殖成本, 另一方面, 长茎葡萄蕨藻净化了鱼虾养殖水体水质, 提高了海水资源的利用率, 促进鱼虾养殖的增产增效。 利用长茎葡萄蕨藻净化 了鱼虾养殖水体水质, 实现藻、 虾、 鱼养殖生态互补, 具有极高的经济和生态 价值。 目前, 生产中尚无通过长茎葡萄蕨藻净化鱼虾养殖水体水质, 进行藻、 虾、 鱼生态互补养殖的报道和实例。
