Fish,after the fishing, if not put in live water, will be inactivated in a short time. And if the weather is hot, the fish will degenerate in a few hours. So for fishing boats to go fish, they will carry a lot of ice.And for some ocean fishing boats, they even install ice machines and cold storage on board, in order to preserve valuable fish in time.
Here, we inventory what kind of ices is suitable for the preservation of fresh fish species, as well as the characteristics of the ices.
I believe when we visit the fish market, we can often see the ice blocks. Fish stalls will generally buy a certain amount of ice blocks, and then crushed by themselves. Crushed ice and fish are mixed in the foam box. So you can achieve the same effect as that refrigerator. The advantage of using ice blocks is that the price is low, and the ice plant will supply ices regularly for the market or the terminal, and some ice plants will also provide crushed ice directly. The disadvantage is that the crushed ice from ice blocks is hard, and angular appearance. It’s easy to destroy the surface of the fish for little attention.
Another kind of ice used for fresh fish is flake ice, which is often used for some more valuable fish preservation. Rule ice shape rules, and soft texture, which will not damage the fish surface And coupled with the relative contact area, it has a higher freezing efficiency. The disadvantage is that the price is high, and because the surface area is large, the ice is easier to melt, always pay attention to add ice always.
There is also a common ice used in fish preservation , which is plate ice. Plate ice can be said to be the combination of block ice and flake ice. Both because of the long freezing time, so have a lower ice temperature, the ice last more durable, but also because of the ruled shapes, large contact area, it has a higher freezing efficiency.
