在四川彭州市葛仙山镇一养殖基地，40余个蓝色养殖桶内，数十万尾耗儿鱼在清澈的"人造海水"中穿 梭。这片仅10亩的园区，通过精准配比微量元素模拟海洋环境，让川渝人餐桌上常见的冰鲜耗儿鱼首次 实现"鲜活供应"。这一突破，正是中国内陆海产养殖技术创新的缩影。 耗儿鱼年消耗量超30万吨的川渝市场，曾长期依赖沿海冰鲜运输。"从海边运活鱼过来，运费高、折损 大。"四川蓝色粮仓生态科技有限公司总经理尹志超说，团队与科研机构合作多年，测试十几种海水晶 配方，才最终攻克"造海"难题。如今，基地已实现耗儿鱼全流程培育，满产时年产能达45万斤，首批活 鱼预计2026年初上市。 四川的探索不止于此。在"天府之肺"雅安市，依托高山冰雪融水形成的优质冷水资源，当地建成总面积 超2000亩的鲟鱼养殖基地，通过科技赋能将生态优势转化为高端水产竞争力。基地采用循环水养殖系统 和智能化监控设备，实时监测水质、温度等关键指标，还与高校合作培育鲟鱼新品种，2024年累计加工 鱼子酱70吨、占全球总产量15%，产品远销欧美、日韩等30多个国家和地区。 12月4日，四川彭州，工作人员查看"人造海水"培育的耗儿鱼长势。王利文 摄 12月4日，四川彭州，" ...
