Method for peeling sea urchin seedlings through onion juice

Abstract

The invention discloses a method for peeling sea urchin seedlings through onion juice. The method is characterized in by including the following steps that onions are smashed, then residues are removed, the obtained onion juice and sea water are mixed to prepare an onion juice solution, the mass-to-volume ratio of the onions to the sea water is 2 kg-2.5 kg: 100 L, an adhering substrate where the sea urchin seedlings adhere is placed inside a net cage, the net cage is soaked into the onion juice solution for 5 s-15 s, the sea urchin seedlings will fall off from the adhering substrate, the net cage is taken out of the onion juice solution, the adhering substrate in the net cage is removed, and finally the net cage is transferred into a breeding pool. The method for peeling the sea urchin seedlings through the onion juice can shorten the time for peeling the sea urchin seedlings and will not affect the seedlings.

Description

technical field [0001] The invention relates to a method for peeling sea urchin seedlings, in particular to a method for peeling sea urchin seedlings with onion juice.

Problems solved by technology

In the traditional peeling operation, skilled workers need to use wooden sticks and other tools to knock the attachment base of sea urchin seedlings, so that the sea urchin seedlings are shaken off from the attachment base. This method is not only time-consuming, but also inevitably damages the seedlings. Seeds will cause a certain degree of damage, and the seedlings will be scattered everywhere, which is not easy to recover
