缘纲与主绳的连接物与鱼种网箱中用的一样。整个网材料是从现成生产的一卷网上剪下来的。一顶规格为5米×5米×3米的完整的养成网箱(包括绳等在内)大约重14.4千克。一卷现成的网材料可以做4只网箱。此外,还要为网箱做一顶网盖,以防止偷窃或逃鱼。为了便于投饵,网盖网目应超出7.5厘米。一只网箱至少可用5年,不过在3年以后,由于阳光中紫外线的辐射,使网变脆,必须更换网顶暴露的30厘米部分。框架:
Edge link with the main rope and fish used in the same cage. The entire web is cut from a roll of ready-made web. A complete cage cage size (including ropes, etc.) of about 5 mx 5 mx 3 m weighs about 14.4 kg. A roll of ready-made web material can make 4 cages. In addition, a net cover should be made for the cages to prevent theft or fledgling. In order to facilitate the feeding, net cover mesh should exceed 7.5 cm. A cage can be used for at least 5 years, but after 3 years, due to the ultraviolet radiation in the sun, the net becomes brittle and the exposed 30 cm portion of the net must be replaced. frame:
