为何处暑开渔?时下“顶鲜”水产是啥?专家解读
Yang Shi Wang· 2025-08-23 09:31
处暑节气,我国沿海地区再度迎来一年一度的开渔盛典。为啥老祖宗偏偏选处暑开渔?咋就不怕气候变 化,年年都能准时"打卡"?最关键的是,上海人的餐桌上,这会儿能吃上哪些"顶鲜"的水产?对这份深 植于海洋生态规律的千年智慧,上海海洋大学副教授张玮带来解读。 处暑吃这些正当时 如今,全球多地传统习俗因气候变暖发生改变,但我国沿海的处暑开渔节却历久弥新。这背后,是跨越 千年的生态智慧与动态调整的现代管理在共同发力。 "尽管海水温度有所上升,处暑作为幼鱼育成、饵料丰富、渔汛开启的'黄金窗口'依然有效。"张玮指 出,现代渔业通过建立综合性渔业资源监测网络,动态追踪关键经济物种(如带鱼、小黄鱼、银鲳鱼、 梭子蟹)的种群数量、洄游路线、产卵场分布及幼鱼补充状况。 基于大数据模型分析,渔业管理者得 以科学应对产卵期偏移、优化休渔时间窗口、评估开渔资源基础,并动态调整休渔时间与范围。 这一 系列举措有效保障了处暑开渔的科学性及渔业资源的可持续利用,使古老的"生态时钟"在现代得以精准 校准。 此外,休渔期恰好为渔民提供了修船补网、积蓄力量的时间,处暑开渔则迎来随洋流涌动的秋季鱼汛 (如舟山渔场因冷暖流交汇形成高产),形成"休养-丰收" ...
