Several common problems encountered during scallop feeding:
1. The layout of the floating scallop cage is too dense. Judging from the layout of the floating rafts at sea, the distance between the platform and the raft is about 5m. Under the instigation of interests, some of the households have added floating rafts among the existing rafts. In order to increase the length of the squats, some of the through-flow channels and waterways between the rows have been blocked. Irregular phenomenon, the short is about 70m, the elders even reach about 200m, and one floating raft is equivalent to the number of shellfish hanging in two early rafts, which not only affects the normal activities of seawater, blocks the navigation channel, but also have security risks.

2. Seed stocking density is too large. The scallop rearing of scallops in Changhai County has experienced a large-scale death since 1984. After many years of research and discussion by experts, it has been analyzed for a variety of reasons including the large feeding capacity and the primary productivity of the sea has reached the limit. Therefore, it should be clearly recognized. The carrying capacity of the sea area is limited.
3. The breeding species is single. A few years ago, shellfish were mainly made up of scallops or bay scallops. When the above two species died, they are now turning to a single species of scallops, and once the scallops are problematic, there is no alternative. Kind to compensate, this single type of feeding method is reversed for the rearward opening of the farmer. Judging from the enquiry situation, the scallops and bay scallops of single-person households are gratifying this year. Therefore, in the absence of new alternatives, scallops, scallops and bay scallops can be raised in a variety of ways.
