Preparation and application method for ocean shellfish extract with food calling effect on loaches

Abstract

The invention discloses a preparation and application method for an ocean shellfish extractive with a food calling effect on loaches. The preparation and application method comprises the following steps: carrying out freezing treatment on mactra veneriformis; taking out shellfish meat and crushing the shellfish meat by using a beating machine; cooking clam nectar in three time periods, continually cooking for 10 minutes after the clam nectar is boiled, continually cooking for 30 minutes after the clam nectar is boiled and continually cooking for 50 minutes after the clam nectar is boiled; preparing the clam nectar to be in three concentrations of 0.025g / ml, 0.1g / ml and 0.4g / ml; filtering the obtained clam nectar by a screen and a filtering machine; mixing the filtered clam nectar with a feed according to a certain ratio respectively; putting raw materials obtained by mixing the clam nectar and the feed into a drying oven to be dried, wherein the drying temperature is 60 DEG C and the drying time is 3 hours; dividing the loaches into 12 groups, wherein each group contains 10 loaches; taking two groups as blank control groups and cultivating; and feeding the loaches by food calling agents with different concentrations, different screen meshes, different proportions of the clam nectar to the feed and different cooking time, and observing and comparing. According to the preparation and application method for the ocean shellfish extractive with the food calling effect on the loaches, the feeding rate of the loaches is increased, the method is simple and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of loach cultivation, and in particular relates to a method for preparing and using a marine shellfish extract capable of attracting food to loach. Background technique [0002] The meat of loach is tender and refreshing, and the taste is even more delicious. The edible part with a protein content of 18.3-21.5 grams per 100 grams is much higher than that of ordinary fish and has high edible value; it also contains 2.8-2.9 grams of fat and 100 calories. -116 kcal, magnesium and calcium 51-459 mg, 154-243 mg, magnesium, phosphorus, iron and vitamins 2.7-3.0 mg, and trace components such as B1, B2 and niacin, often eating loach can treat some diseases, loach The nature and taste are sweet and flat, and it is recorded in medical books that fish has the function of warming the middle and replenishing qi; such as quenching thirst, diuresis, impotence, and has a certain preventive effect on hemorrhoids. , Acute ma...
