2規(guī)范性引用文件

下列文件中的內(nèi)容通過文中的規(guī)范性引用而構(gòu)成本文件必不可少的條款。其中，注日期的引用文件，

僅該日期對應(yīng)的版本適用于本文件；不注日期的引用文件，其最新版本（包括所有的修改單）適用于本

文件。

GB3838地表水環(huán)境質(zhì)量標(biāo)準(zhǔn)

GB11778鳙魚苗、魚種

GB/T27638活魚運輸技術(shù)規(guī)范

NY5071無公害食品漁用藥物使用準(zhǔn)則

SC/T1149大水面增養(yǎng)殖容量計算方法

3術(shù)語和定義

下列術(shù)語和定義適用于本文件。

3.1

回捕率recapturerate

放養(yǎng)對象回捕的個體數(shù)量占放養(yǎng)數(shù)量的百分比（％）。

4容量評估

放養(yǎng)容量評估按照SC/T1149的規(guī)定進行。

5魚種準(zhǔn)備

5.1魚種要求

魚種來源、魚種質(zhì)量、魚種檢疫檢驗應(yīng)符合GB11778的規(guī)定。

5.2魚種運輸

魚種運輸應(yīng)符合GB/T27638的規(guī)定。

DB43/T2393—2022

6生態(tài)放養(yǎng)

6.1放養(yǎng)時間

春季3-4月；夏季7-8月；冬季1-2月。

6.2放養(yǎng)地點

宜選擇敞水區(qū)且遠離進出水口的水域。

6.3魚種放養(yǎng)

放養(yǎng)量根據(jù)公式（1）進行計算，

N=（F/W）×（1/f）······················································（1）

式中：

N——為放養(yǎng)數(shù)量，單位為尾；

F——為鳙的生產(chǎn)潛力，單位為千克（kg），其計算按照SC/T1149的規(guī)定進行。

W——為鳙的起水平均重量，單位為千克（kg）；

f——為鳙的回捕率，單位為百分比（％）。

放養(yǎng)規(guī)格根據(jù)SC/T1149的規(guī)定進行湖泊容量評估時所得天然餌料豐富度來選擇。天然餌料豐富

時，放養(yǎng)大規(guī)格魚種，反之則放養(yǎng)小規(guī)格魚種。

6.4放養(yǎng)方法

宜在無大風(fēng)、無大雨的天氣放養(yǎng)。魚種運達目的地后，應(yīng)分別測量運輸容器和放養(yǎng)湖泊的中水溫，

放養(yǎng)大規(guī)格魚種時，水溫相差不超過3℃，放養(yǎng)小規(guī)格魚種時不超過2℃，否則，應(yīng)采取逐漸換水的

方式來減小溫差。宜用機動船將魚種運至預(yù)定的放養(yǎng)地點分散放養(yǎng)，放養(yǎng)前魚種應(yīng)按NY5071的規(guī)定

進行消毒。放養(yǎng)后不投食，自由攝食天然餌料。

7成魚捕撈

7.1捕撈時間

捕撈一般在當(dāng)年10月下旬開始，大規(guī)模捕撈宜在11月下旬至12月下旬。根據(jù)需要也可在5-9

月分散捕撈，滿足優(yōu)質(zhì)水產(chǎn)品的供應(yīng)。

7.2捕撈規(guī)格

捕大留小，最小捕撈個體規(guī)格宜大于1.5kg，小于此規(guī)格個體宜放回湖中。

7.3捕撈強度

應(yīng)符合SC/T1149的規(guī)定。

8運輸與標(biāo)識

8.1活魚運輸

2

DB43/T2393—2022

活魚的運輸應(yīng)符合GB/T27638的規(guī)定。

8.2產(chǎn)品標(biāo)識

產(chǎn)品運輸前應(yīng)記錄產(chǎn)品名稱、產(chǎn)地、生產(chǎn)單位及廠（場）址，出售時應(yīng)附產(chǎn)品信息標(biāo)簽進行標(biāo)識。

9效果評估

9.1抽樣調(diào)查

定期、定點，尤其是在秋季大規(guī)模捕撈時對放養(yǎng)鳙進行抽樣調(diào)查。調(diào)查內(nèi)容包括鳙的體重、全長、

體寬、體高、年齡、產(chǎn)量、回捕率等，記錄內(nèi)容見附錄A表A.1鳙放養(yǎng)和回捕情況記錄表。

9.2效益評估

在每個放養(yǎng)周期結(jié)束時對鳙放養(yǎng)的經(jīng)濟效益和生態(tài)效益進行綜合評估，特別關(guān)注放養(yǎng)對浮游生物群

落結(jié)構(gòu)等的變化以及水質(zhì)指標(biāo)的影響。編寫評估報告，基于評估結(jié)果調(diào)整鳙放養(yǎng)密度和放養(yǎng)規(guī)格。
