Problems solved by technology

Chemical drug treatment has strict operational technical requirements, precise time node control, high cost of drugs and cannot be recycled, and high quality requirements for practitioners.
The traditional method of attaching first and then peeling off is not only low in production efficiency, but also the shell of the larvae is easily crushed during the operation, making it difficult to scale up

Embodiment 1

[0022] The attachment base monomer is composed of a support rod and a strip-shaped black rubber cloth suspended on the support rod. The material density of the strip-shaped black rubber cloth is about 1.4g / cm 3 , has the characteristics of sinking water, and the elongation rate is greater than 4.5.

[0023] Specifically, the strip-shaped black rubber cloth is mainly composed of butyl rubber, which is synthesized from isobutylene and isoprene with the addition of carbon black and an anti-aging agent in a conventional manner; or it is obtained commercially.

[0024] Supporting seedling picking device, the seedling picking device includes aquaculture tank 1, attachment base monomer 2, card slot 3 for fixing attachment base, filter drum 4, water inlet pipe 5, drain pipe 6; wherein, several attachment base monomers are placed side by side in a The main body of the seedling-picking facility is formed in the culture tank of several card slots, and the attachment substrate is under th...

[0031] Comparison experiment of different adhesion base adhesion effects

[0032] Experimental method: In a near-cuboid culture tank with a width of 90 cm and a height of 80 cm, the eye-spot larvae of Oyster oyster were placed at a density of 20 / mL (the eye-spot rate was about 30%), and the circulating aquaculture mode was used for daily cultivation. The daily water change is about 5%, and the feeding amount is (Isochrysis) 800cellslarva -1 h -1 , the incubation temperature was 24°C, and the experiment was carried out in a light-shielding room. The experiments were carried out with five kinds of attachment bases according to figure 1 The method shown is processed into a strip shape and hung in the corresponding card slot. The suitable width of each rubber cloth is about 3cm and the length is 60-70cm. The interval between the two suspended rubber cloths is 4-5cm. Connect with the support rod with cotton rope. The five attachment bases are black rubber cloth, yellow rubber c...

Abstract

The invention belongs to the field of aquaculture engineering and specifically relates to a substratum for producing oyster monomer fries and a fry collection device matched with the substratum. A substratum monomer consists of a support rod and a strip-shaped black rubber cloth suspended on the support rod, wherein the density of the strip-shaped black rubber cloth is about 1.4g / cm<3>, the strip-shaped black rubber cloth has sinking characteristics, and a stretch rate of the strip-shaped black rubber cloth is larger than 4.5. According to the substratum for producing the oyster monomer fries and the fry collection device matched with the substratum, production of the oyster monomer fries does not depend on abnormal induced drugs, fry collection facilities can be all recycled, and any damages are hardly produced during fry stripping.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to an attachment base for producing oyster single seedlings and a matching seedling picking device. Background technique [0002] At present, there are three main ways to obtain individual oyster seedlings: one is to treat the oyster larvae at the eye point stage with drugs such as adrenaline or 5-HT, so that the larvae can complete metamorphosis without attachment, thereby obtaining individual spat (Grant, M.N., D.W.Meritt&D.G.Kimmel.2013.Chemical induction of settlement behavior in larvae of the easternoyster Crassostrea virginica (gmelin).Aquaculture402-403:84-91.; MesAquaculture40, C., A.Silva, V.Maneiro, A.Pazos, SLJ.L.
