Problems solved by technology

Each crab cage needs 50-60 g of fresh fish pieces each time, and can only be used once. The fish pieces discarded after use are discarded in the ocean, causing certain damage to marine ecology
Using fresh fish pieces as bait not only consumes a large amount of fish natural resources and increases production costs, but also fishermen need to frequently change bait during operation, which is cumbersome to operate

preparation example Construction

[0031] (1) Preparation of the enzymatic hydrolyzate of Qingzhan fish: remove the head, bones, viscera and fins of Qingzhan fish, wash and drain, and crush it with a tissue grinder for 1 min until it becomes minced for later use.

[0032] Weigh papain, add water to dissolve it, put it in a constant temperature oscillating water bath and heat it up to the set temperature, then add minced green squid meat, adjust the pH value with phosphate buffer (PBS, 0.5mol / L, pH=6.5), the enzyme untie.

[0033] The parameters of the enzymatic hydrolysis process are as follows: weigh 1000g of minced green fish meat, the amount of papain added is 2000-3000U / g, the enzymatic hydrolysis time is 3-5h, the pH is 6.5-7.0, and the temperature in the constant temperature oscillating water bath is 50± 2°C, after the hydrolysis is complete, take it out and place it in a boiling water bath to inactivate the enzyme for 10-15 minutes. Then centrifuge at 4000-5000r / min in a centrifuge for 10-15min, and tak...

Abstract

The invention discloses an artificial mixed bait for portunus trituberculatus and a preparation method thereof. The objective of the invention is to overcome disadvantages and deficiencies of a mackerel bait used in crab pot operation for portunus trituberculatus in the prior art. The artificial mixed bait for portunus trituberculatus provided by the invention comprises, by weight, 25 to 40% of fish meal, 40 to 55% of pregelatinized starch, 12 to 20% of a Maillard reaction product of enzymatic hydrolysis liquid of mackerel and 3 to 8% of betaine. The artificial mixed bait has the advantages of low cost, a long shelf life on board and a long-lasting induction effect. Replacement of a fresh fish block bait with the artificial mixed bait enables consumption of the natural resource of fishes to be reduced and fighting between crabs and human beings for food to be avoided; moreover, the artificial mixed bait is commercially packaged and convenient to store, transport and operate and improves the level of mechanization of crab pot operation.

Description

technical field [0001] The invention relates to the technical field of marine fishing, in particular to an artificial bait for Portunus trituberculatus and a preparation method thereof. Background technique [0002] Portunus trituberculatus ( Portunus trituberculatus ) commonly known as Portunus, belonging to Crustacea, Decapoda, Portunidae, is the most important large-scale marine economic crab in my country, and has great economic significance. Swimming crabs are mainly distributed in China, North Korea, Japan and other seas. They have the advantages of long fishing season, high yield, large body and rich meat, delicious meat, unique flavor and rich nutrition, and are sold well in domestic and foreign markets. With the decline of fishery resources of traditional main economic species, swimming crab fishery resources are getting more and more attention, and it has become an important species in coastal areas to export foreign exchange. wide, with a large number and variet...
