[0050] Also make B group comparative test of the present invention in addition while group A test:

[0051] The invention includes the steps of picking seedlings, lighting and changing water, applying nutrient salts, treating sclerotids, laying eggs, changing water after laying eggs, cultivating in flowing water after attachment, and peeling young abalone, and is characterized in that:

[0052]1. Start cultivating algae one and a half months before harvesting seedlings, that is, start on March 15th, cultivate water at 14°C, attach 1,000 sheets of basement film to each pond, use a layer of sunshade to increase the light rate of 2000lx-3000lx, and change it every 5 days Water once, change 1 / 2 water each time, and pour the pool every 10 days. Before pouring the pool, manually wash away the thicker aged algae growing on the attachment base, and then evenly arrange in another pool filled with fresh seawater to continue algae cultivation. Repeat 4 times to manually wash the aged alg...

Abstract

The invention discloses a benthic diatom culture method for growing seedlings and an abalone fry culture method, which relate to an abalone culture technology. The invention is characterized by comprising the following steps: (1) starting culturing algaes 45 days before pulling seedlings, keeping the culture water temperature at 14 DEG C and the illuminance between 20001 and 30001x, controlling the light between 10001 and 15001x at the last culture after screening and eliminating algae culture for one and half a month, and laying ovum after 7 days; (2) adding nutrient salt at primary culture,wherein the adding ratio of N:P:Si:Fe is 5:1:1:1(ppm); (3) laying ovums about 5 millions for each pool and carrying out micro inflation; (4) changing water regularly after the ovums are laid and changing water twice a measuring range which is 24 hours; (5) carrying out running water culture after the ovums swim for 5 to 6 days and are adhered; (6) controlling the illuminance within 10001x after larvas metamorphose; and (7) dumping the pool after treating copepods at about 30 days of the culture period, adjusting the illuminance between 15001 and 20001x and peeling off baby abalones after about45 days. The methods have the advantages of improving the yield and preventing and treating a plate stripping disease.

Description

Technical field: [0001] The invention relates to abalone culture technology, and is particularly suitable for the cultivation of benthic diatoms for raising seedlings. Background technique: [0002] Benthic diatoms are the pre-bait for abalone larvae, and their species and quality play a crucial role in the success or failure of artificial breeding of abalone. Its variety is suitable and sufficient in quantity can not only prolong the attachment and metamorphosis rate of abalone larvae, but also effectively prevent "stripping disease", prolong the time on the plate, realize the purpose of peeling off large-scale seedlings, and achieve a high survival rate. Young abalones feed on benthic diatoms (Lunarella, Navicula, Ovalella) and single-celled green algae (Platinella) that contain more starch and polysaccharides, but at the beginning of artificial inoculation, small Navicula and The proportion of single-celled green algae is not very high. With the control of artificial cul...
