Grass carp feed prepared from ecologically harvested submerged plant and preparation method

Abstract

The invention discloses grass carp feed prepared from ecologically harvested submerged plant and a preparation method. The grass carp feed is prepared from plant powder, agar, pure water, salt and vitamins in a certain proportion, and the preparation method comprises the following steps: (1) cleaning ecologically harvested submerged plant, airing or roasting the submerged plant by roasting equipment at 35-40DEG C until the submerged plant is completely dehydrated; (2) pulverizing the plant and screening with a 10-30 mesh sieve to obtain plant powder; (3) uniformly mixing the plant powder with the salt and vitamins to obtain a plant mixture; (4) uniformly mixing the pure water with agar, boiling the mixture at 80-90DEG C to obtain agar homogenate; (5) after the agar homogenate is cooled, pouring the plant mixture into the agar homogenate, and homogenizing to obtain plant dough; and (6) preparing the plant dough into pellets by using a feed pellet machine, and then baking the pellets in an oven to obtain the submerged plant feed for grass carps. The grass carp feed solves the problem of secondary environmental pollution caused by overgrowth of submerged plant in ecological restoration of water, has simplicity of processing, utilizes the raw material as a resource, saves cost, reserves the original nutrient value of submerged plant and promotes the growth of grass carps.

Description

technical field

[0001] The invention relates to the technical field of fish feed and environmental protection, in particular to a grass carp bait made from ecologically harvested submerged plants, and also relates to a preparation method for making grass carp bait from ecologically harvested submerged plants, which is suitable for the ecological restoration process of harvesting water bodies Submerged plants that may cause secondary environmental pollution due to overgrowth. Background technique

[0002] At present, the water environment of lakes and rivers in my country is seriously polluted, which has brought many adverse effects on water environment quality, water ecological safety, drinking water safety and water body landscape. The technology of using submerged plants to restore water bodies in situ has attracted more and more attention, such as black algae, foxtail algae, bitter grass, chrysanthemum, hornwort, sundew, glabra, water shield grass, and bermudagrass Subme...
