对虾用头部的后三对附肢充当口器,用嗅觉觅食,抱饵后游到安静场所,尔后用两对片状的小颚抱持颗饵,协同一对呈齿状的大颚,逐步切碎并咀嚼。由上可知,整个投饵和对虾采食过程,要求颗饵须经得起海水浸泡与搅动。显然,对虾配合饲料的诸营养素达到某一水平之后,其在水中的稳定性直接影响着饲料利用率和水质理化指标。福建省水产厅规定,对虾颗粒料经海水浸泡吸水膨润在120分钟
After the shrimp with the head of the three pairs of appendages as a mouthpart, foraging for food, after the bait swim to a quiet place, then with two pairs of flapping small jaw holding bait, synergy with a toothed jaw , Gradually chopped and chewed. From the above we can see that the whole feeding and shrimp feeding process requires the bait to withstand the seawater soaking and stirring. Obviously, shrimp feed nutrients reach a certain level, its stability in the water directly affects feed utilization and water quality physical and chemical indicators. Fisheries Department of Fujian Province provides that shrimp pellets by the sea water soaked swelling in 120 minutes
