为探究LED灯对鲻(Mugilcephalus)刺网捕获效率及副渔获物组成的影响,于2023年5—6月在荣成北部海域使用布设5种不同光色(红、白、黄、蓝、绿)和3组不同数量(2、4、6盏) LED灯的三重刺网进行捕捞实验。以单位捕捞努力量渔获数量(CPUE)和单位捕捞努力量渔获重量(WPUE)为指标,采用广义线性混合效应模型(GLMM)评估LED灯对鲻捕获效率的影响。结果表明,LED灯会对鲻捕获效率产生显著影响,且不同光色和数量对鲻捕获效率的影响存在差异。对比不同光色的LED灯,绿色LED灯效果最佳,与未布设LED灯的对照网相比,布设2、4、6盏绿灯的实验网鲻CPUE分别显著提高了50.72%、97.46%和98.07%(P0.05)。实验网与对照网捕获鲻的体长分布均无显著差异(P>0.05)。同时,布设LED灯提高了花鲈(Lateolabraxmaculatus)和许氏平鲉(Sebastesschlegelii)等副渔获物的捕获效率;特定光色的LED灯有助于减少副渔获物中花鲈和许氏平鲉的幼鱼比例。研究认为,绿色LED灯在鲻刺网中具有较好的应用前景。本研究可为LED灯在鲻刺网渔业中的合理应用提供参考。

阴影效应是影响人工鱼礁诱集效果的主要因素之一,为研究许氏平鲉(Sebastes schlegelii)对人工鱼礁不同阴影情况的行为响应,采用室内模拟实验方法,在实验水槽顶部固定光源,共设计3组实验:A组实验探究不同阴影面积的鱼礁模型对实验鱼的诱集效果;B组实验探究不放置鱼礁模型、悬挂不同开孔率顶板对实验鱼的诱集效果;C组实验探究阴影面积相同但开孔数量不同的鱼礁模型对实验鱼的诱集效果;对照组实验水槽中不放置鱼礁模型、不悬挂顶板。观察并记录许氏平鲉幼鱼(体长(5.06±0.09)cm,体质量(3.22±0.16)g)在水槽中的行为与分布特征。研究表明:3个实验组中许氏平鲉在鱼礁放置区域的出现率均显著高于对照组和其他区域;A组实验中,许氏平鲉在鱼礁放置区的平均出现率随着鱼礁阴影面积的增大而上升;B组实验中,许氏平鲉在顶板放置区的平均出现率显著高于对照组,但不同水平组之间差异不显著;C组实验中,开孔数为1时许氏平鲉在鱼礁放置区的平均出现率与开孔数为9时相近且高于开孔数为4和6时。研究结果表明,阴影面积越大的人工鱼礁对许氏平鲉的诱集效果越好,阴影面积相同时开孔数较多的人工鱼礁能够在提供良好庇护所的同时保证诱集效果。
