今年8月23日是处暑，我国沿海地区迎来盛大的开渔节。为啥选在处暑开渔？长三角地区百姓的餐桌 上，又能吃上哪些"顶鲜"的水产？ 《 人民日报 》（ 2025年08月28日 10 版） 上海海洋大学水产与生命学院副教授张玮介绍，从海洋生态看，暮春至夏季是众多海洋生物的繁殖黄金 期，东海水域的小黄鱼、银鲳、梭子蟹，以及红虾、竹节虾等，都会在这时候集中产卵孵化。处暑前 后，它们的繁殖高峰期基本结束，此时开渔能较大程度避免捕捞亲鱼，守护海洋生态平衡。 (责编：胡永秋、杨光宇) "像大黄鱼、带鱼这些上海人爱吃的鱼，幼鱼从夏天长到处暑，体长能有5—10厘米，刚好能从普通渔网 网眼里'溜'走。既不耽误渔民捕鱼，又给小鱼留下长大的机会。"张玮表示，处暑开渔是对海洋物种生 命周期的精准把握——既避开关键繁殖期以保护亲鱼和幼苗，又等幼鱼长到相对安全的尺寸，为渔业资 源的永续利用打下坚实基础。 我国沿海地区的处暑开渔节历久弥新，这背后是延续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，处暑时节作为幼鱼育成、饵料丰富、渔汛开启的'黄金窗口'依然有效。"张玮 说，现代渔业通过建立综合性渔业资源监测网络，动态追 ...

央视网消息：过了处暑节气，距离大面积秋收越来越近，因气候和作物种类的不同，一些地方的种植户已经在这两天率先享受到了收获的 喜悦。 眼下，黑龙江各地鲜食玉米进入丰收旺季，在齐齐哈尔市依安县，2.4万亩鲜食玉米进入收获季，当地采用机械收割加快抢收，预计9月中 旬可完成全部收获。今年，这里采用大垄密植栽培技术，可以提高产量。秸秆做成青储饲料，推动种养循环。 黑龙江省齐齐哈尔市依安县先锋乡集福村党支部书记赵忠国称："引进甜糯玉米新品种，实行订单种植，亩产达1.5吨，比传统种植增加效 益60%。从种植到采收全程机械化，每亩增收超460元。" 在湖北孝昌，花生迎来丰收旺季。田间地头机器轰鸣，一串串饱满的花生果带着泥土清香破土而出，花生摘果机将饱满果荚与秸秆快速分 离，拖拉机穿梭运送，采收过程高效有序。 湖北省孝昌县邹岗镇种植大户杨仙华称："你看这花生，还是挺饱满的。每亩地产600—700斤，每亩地卖2000多元，还是不错的。" 这两天，新疆沙湾市1.83万亩加工番茄陆续进入采收季。番茄采收机轰鸣着在田间行进，一次性完成采摘、果秧分离、装车等多个流程， 随后被运往加工厂，制成番茄酱、番茄丁等产品，销往全国各地。 加工番茄种 ...

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" ...
