Description

A special compound feed for clean sea cucumber and its processing method

technical field

The invention relates to a clean type sea cucumber special compound feed and a processing method thereof. Specifically, the clean type sea cucumber special compound feed is produced by adopting a nutrient slow-release technology combined with adding enzymatic hydrolyzed plant protein, and belongs to the technical field of aquaculture feed processing.

Background technique

In recent years, sea cucumber farming has begun to enter intensive high-density farming, which consumes a large amount of marine algae such as sargassum, sargassum, and kelp, which not only causes a shortage of seaweed resources, but also increases the price of seaweed. Although the current use of terrestrial plant protein to replace algal flour has relieved the pressure on algal flour to a certain extent, it often leads to lower feeding rates and slower growth of Apostichopus japonicus. low ratio. The reason is that compared with fish and shrimp, the digestive enzyme spectrum of sea cucumber itself is relatively simple. Sea cucumber uses a large amount of food to ingest more bait to make up for the shortcoming of low digestion and absorption, and simple substitution leads to its digestive enzymes. Absorptive capacity is further reduced. In addition, the japonicus japonicus feed mostly uses powdered feed, and the powdered feed loses a lot in water, especially some soluble nutrients are easily lost into the water, which relatively reduces the effective intake of japonicus japonicus. At the same time, the lost nutrients often cause serious pollution at the bottom of the pool, and the compound feed stuck to the bottom of the pool is not easy to clean up, which makes the bottom more polluted, causing the obvious "avoidance behavior" of sea cucumbers, increasing the death of sea cucumbers, and bringing harm to sea cucumber cultivation. come loss. Although the flake feed has a certain resistance to loss, it is different from the powder feed, and the flake feed often sinks in a small area at the bottom. Due to the lack of strong food-attracting substances in the feed formula, it is difficult for the sensory organs of sea cucumbers to be absorbed in a short time. The position of the feed is detected within, which relatively increases the residence time of the flake feed in the water, which in essence increases the loss of nutrients. One of the effective ways to solve these problems is to design a strong and stable compound feed rich in attractant substances according to the loss kinetics of various nutrients in the formula, so that it can disintegrate layer by layer in water and slowly A small amount of food-attracting substances is released to lure sea cucumbers to actively eat. At the same time, the compound feed needs to have digestible substances to help improve the digestion of nutrients by sea cucumbers.

Contents of the invention
