Benefits of technology

This patented technology allows for complete replacement of naturally occurring fishhoes with artificially created ones that are more efficient than traditional methods like tuna or salmon ropes used during seawater-based cultures. It also saves time by replacing existing sources instead of purchasing new ones from outside vendors.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding new ways to improve ocean crops' ability to produce seed without causing environmental damage or reducing their potential benefits overcomes issues such as limited availability caused by poorly controlled water quality conditions during harvesting processes like traditional methods.

Embodiment 1

[0016] A compound feed for cultivating planktonic larvae of tropical sea cucumber Yuzu and sea cucumber, the feed preparation method is as follows: 10 g of sargassum powder (Laizhou Haifu Feed Co., Ltd.), 200 mL of chilled sargassum algal liquid, and stable diatom seeds (Luoyang Yuyao Technology Co., Ltd.) 2g, chlorella powder (Dongtaici Centennial Bioengineering Co., Ltd.) 2g, yeast powder (Angel Yeast Co., Ltd.) 2g, mixed in 5L of clean seawater, put into a 500-mesh mesh bag, The filtrate is collected by filtration, which is the compound feed for cultivating the larvae of the tropical sea cucumber Yuzu sea cucumber in the planktonic stage. The preparation method of chilled fresh Sargassum algae liquid is as follows: freshly collected Sargassum algae, stored at -20°C, take 80g when using, add 80g of water, use a household grinder to crush to the smallest particle size, then add 2.0L of water, mix well, Store at 4 ℃, that is, chilled Sargasso algae liquid.

Embodiment 2

[0019] Set up a pond of Yuzu sea cucumber larvae experimental group with a water body of 30m 3 , each day at 8:00 am and 7:00 pm each feeding the compound feed in the above Example 1 once. One control pool of sea cucumber larvae was set up. The development stage and density of sea cucumber larvae were the same as those of the experimental group, and the water body was 30 m. 3 , feed fresh Chaetoceros algae once a day at 8:00 am and 7:00 pm according to the conventional method. After 21 days, the sea cucumber larvae in the experimental group and the control group were counted three times and averaged. The results showed that the density of larvae in the experimental group pond was 68±6 / L water body, and the density of larvae in the control group pond was 72±4 / L water body, and there was no significant difference between the two. Microscopic observation was carried out on the sea cucumber larvae in the experimental group and the control group, and the results showed that: the ...

Embodiment 3

[0021] A compound feed for cultivating planktonic larvae of tropical sea cucumber Apostichopus japonicus, the feed preparation method is as follows: 8 g of sargassum powder (Laizhou Haifu Feed Co., Ltd.), 150 mL of chilled sargassum algal liquid, and stable diatom seeds (Luoyang Yuyao Technology Co., Ltd.) 1g, chlorella powder (Dongtaici Centennial Bioengineering Co., Ltd.) 1g, yeast powder (Angel Yeast Co., Ltd.) 1g, mixed in 5L of clean seawater, put into a 500-mesh mesh bag, The filtrate is obtained by filtration, which is the compound feed for the planktonic larvae cultivation of A. japonicus. The preparation method of chilled Sargassum algae liquid is as follows: freshly collected Sargassum algae, stored at -20°C, take 50g when using, add 50g of water, use a household grinder to crush to the smallest particle size, then add 1.5L of water, mix well, Store at 4 ℃, that is, chilled Sargasso algae liquid.

Abstract

The invention discloses a compound feed for breeding larvae of tropical sea cucumbers in a planktonic period and a preparation method of the compound feed. The preparation method of the compound feed comprises the following steps of mixing 8-12 g of gulfweed powder, 150-250 mL of chilled gulfweed liquid, 1-3 g of stable diatom species, 1-3 g of chlorella powder and 1-3 g of yeast powder in 5 L of clean seawater, putting a mixture into a 500-mesh net bag, filtering, and taking a filtrate, thereby obtaining the compound feed for breeding the larvae of the tropical sea cucumbers in the planktonic period. The compound feed for breeding the larvae of the tropical sea cucumbers in the planktonic period can completely replace natural bait chaetoceros, and the purposes of saving manpower and material resource cost and guaranteeing stable sea cucumber breeding work are achieved.
