Problems solved by technology

But these methods all have certain drawbacks, although the reproduction and the growth of macroalgae can be controlled by arranging sunshade net to regulate light, but also have certain influence to the reproduction and growth of unicellular algae, and purchase sunshade net, increased production cost; Herbicides destroy the ecological environment of ponds, and improper dosage can also cause adverse effects on sea cucumbers; artificial fishing is labor-intensive and inefficient

Embodiment Construction

[0008] Below in conjunction with embodiment, the present invention will be further described.

[0009] Putting the algae hook shrimp into the sea cucumber breeding pond, the algae hook shrimp freely inhabits in the seaweed clusters such as Enteromorpha and clasteids or on the leaves, and eats a large amount of macroalgae such as enteromorpha and clasteids, which can inhibit the growth of these macroalgae. reproduce and grow. Algae hooked shrimp symbiosis with sea cucumber in the sea cucumber culture pond, does not affect the normal growth and development of sea cucumber. When the macroalgae in the pond grow vigorously, the input algal hook shrimp will reproduce naturally, and the population number will also increase accordingly. Conversely, when the macroalgae in the pond decreases, the input lobster will gradually die naturally due to the lack of habitat and food, and its population will also decrease, and the dead lobster will become the food for sea cucumbers.

Abstract

The invention discloses a method for inhibiting growth of macroalgae in an Oplopanax elatus culture pond. Amphithoe japonica that can eat sea grass, Cladophora and other macroalgae is put into the Oplopanax elatus culture pond, to effectively inhibit reproduction and growth of macroalgae. The method can keep balance of natural ecology and improve the environment of Oplopanax elatus pond culture, and is favorable for growth of Oplopanax elatus.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for inhibiting the growth of large algae in sea cucumber culture ponds. Background technique [0002] Sea cucumber has high nutritional value, and has become one of the important breeding objects in my country's aquaculture industry in recent years. In the process of cultivating sea cucumbers in ponds, large algae such as Enteromorpha and Cladophora often reproduce and grow in large numbers, which will cause many harms to sea cucumber cultivation: First, these large algae will lead to poor water quality and affect the individual species in the pond. The normal reproduction and growth of algae caused sea cucumbers to lack bait; secondly, these macroalgae bloomed in large quantities at the bottom of the pond, occupying the activity space of sea cucumbers and entangled sea cucumbers, hindering the activities of sea cucumbers; thirdly, these macroalgae Death and rot in ...
