Problems solved by technology

[0002] Tiger squid grows rapidly, and can grow up to 4kg a year. It is a very ideal breeding species, but there is no breakthrough in artificial breeding technology. The main problem is that the early nutritional requirements of tiger squid are not clear, resulting in early seedlings and death. The rate is very high, and large-scale breeding is difficult
In addition, there is no more practical technology to use in brood feeding and larva opening bait.

Embodiment

[0017] Example: refer to Figure 1 to Figure 3 , the tiger squid seedling raising method, it comprises the following steps:

[0018] Temporary parenting: put the parent body in the cement pond for temporary cultivation, the stocking density of the parent body is 0.5-2 per square meter; the depth of the cement pond is 1.5-3 meters, and the bottom of the pond is covered with 10-20 cm thick fine sand; temporary cultivation of sea salt The salinity is 25-35‰, and the water temperature is 17-31°C. In this embodiment, the preferred salinity is 35‰, and the water temperature is 20°C. Keep constant running water, shade, inflate, keep quiet, and use the clamp-type feeding device to feed fresh and live small miscellaneous fish and shrimp; the clamp-type feeding device can improve the utilization rate of bait, and the feeding rate is also higher than the existing The technology is better, it helps the body to strengthen its physique, and it can effectively prevent the water quality de...

Abstract

The invention discloses a pharaoh cuttlefish breeding method which comprises steps of parent temporary rearing, egg collection, egg incubation and larva cultivation. A rope holding type cultivation feeding device is utilized to feed the pharaoh cuttlefish with fresh small fishes and shrimps, therefore, the utilization rate of baits is increased, the feeding rate is higher than that of the prior art, physique of parents is invigorated, and worse water quality caused by residual feeds can be effectively avoided. Compared with the prior art, a pharaoh cuttlefish egg collection device is high in egg adhesion rate and easy to transport and transfer. By means of a mode of standing the pharaoh cuttlefish egg collection device adhered by egg strings in air for 1-3 minutes, water on the surface of the egg strings is drained off, stimulation is performed on the surfaces of egg membranes of the pharaoh cuttlefish, and the membrane coming rate is higher than that of the conventional technological means. Therefore, the artificial offspring seed cultivating method has the advantages of being convenient to operate, small in parent loss, high in membrane coming rate of eggs, less in water pollution and suitable for large-scale production.

Description

technical field [0001] The invention relates to a method for raising seedlings of cephalopods, in particular to a method for raising seedlings of tiger squid. Background technique [0002] Tiger squid grows rapidly, and can grow up to 4kg a year. It is a very ideal breeding species, but there is no breakthrough in artificial breeding technology. The main problem is that the early nutritional requirements of tiger squid are not clear, resulting in early seedlings and death. The rate is very high, and large-scale breeding is difficult. At present, the used ovipositors for cephalopod indoor artificial seedlings are mostly red bricks, cement hollow bricks or branch-like plastics, which are heavy and not suitable for hanging when hatching, and are extremely inconvenient to operate. Such as the Chinese invention patent application "Changyao egg picker", application number 200810230010.9, which discloses a long steep egg picker, which is characterized in that the egg picker is wel...
