Description
Technical Field
The invention relates to the technical field of sea urchin ecological breeding, in particular to an ecological breeding method of sea urchin seedlings in the Strongylocentrotus intermedius.
Background
The Strongylocentrotus intermedius (Strongylocentrotus intermedius) also called Strongylocentrotus intermedius has the characteristics of good gonad color, sweet taste and the like, and is one of the most economic varieties of edible Strongylocentrotus intermedius in the world. Therefore, many researchers have conducted a great deal of research on the growth and development of the echinacea, nutritional feeds, and culture modes.
In recent years, with the intensive development of artificial breeding research on echinus intermedius, it is found that problems still exist in the breeding of echinus intermedius, for example, the breeding mode of seedlings is single, the shallow sea breeding cost is high, the real-time monitoring is difficult, the economic efficiency is low, and unfavorable performances such as the decline of the vitality of echinus seedlings and the slow growth of echinus seedlings can also occur. Therefore, in order to solve the problems of weak seedling stress resistance, low input-output ratio and the like of the strongylocentrotus intermedius, the existing culture mode needs to be improved so as to obtain excellent strongylocentrotus intermedius seedlings with quick growth, strong disease resistance and high yield, and improve the culture efficiency and the economic benefit.
In the Stichopus japonicus culture research, abundant nutritive salt in a pond water body induces large algae such as enteromorpha, ulva, cladophora and the like to frequently burst, competitively inhibits the propagation and growth of benthic microalgae, so that not only can the source of live bait of Stichopus japonicus be reduced, but also the activity space of the Stichopus japonicus can be occupied, the normal activity and ingestion of the Stichopus japonicus can be inhibited, and even the massive death of the Stichopus japonicus can be caused. Since the echinus intermedius likes to eat large-scale algae such as enteromorpha, ulva, cladophora and the like, the applicant puts small-size echinus seedlings into the stichopus japonicus culture pond so as to reduce harmful algae in the stichopus japonicus culture pond, avoid outbreak of large-scale algae and obtain the echinus intermedius with high survival rate and higher growth speed.
Disclosure of Invention
In order to solve the problems, the invention aims to provide an ecological breeding method by utilizing sea urchin intermedia seedlings, which is an ecological synergistic breeding technology by taking sea urchins intermedia as an ecological adaptive variety and efficiently utilizing natural productivity of a stichopus japonicus pond breeding system in a low-temperature period, can efficiently utilize natural baits in water, improves economic benefits of a stichopus japonicus pond, and obtains the sea urchins intermedia with high survival rate and higher growth speed.
In order to achieve the above object, the technical solution of the present invention is as follows.
An ecological breeding method of strongylocentrotus intermedius seedlings comprises the following steps:
s1, putting the sea urchin seedlings in the middle ball into the stichopus japonicus pond every autumn when the water temperature is 10-18 ℃; the specification of the sea urchin fry of the Strongylocentrotus intermedius is that the shell diameter is 1-2 cm, and the fry throwing density is 20-60 pieces/m2(in terms of water area);
s2, monitoring and counting the number of macroalgae in the stichopus japonicus pond, and calculating the food intake of the echinococcus intermedia according to the counting result; when the quantity of the macroalgae is less than the food intake of sea urchins, putting the macroalgae into the stichopus japonicus pond;
s3, catching the Strongylocentrotus intermedius in the spring of the next year when the water temperature rises to 20-23 ℃, and transferring the Strongylocentrotus intermedius with the shell diameter less than 4.5cm to the sea area for raft culture.
It should be noted that the strongylocentrotus intermedius is favorable for eating ulva and kelp, and can also be favorable for eating harmful algae in the culture water body such as enteromorpha and cladophora. The algae roughly processed in the digestive tract of sea urchin can easily become the food of Stichopus japonicus. Therefore, the sea urchin with the middle ball is very suitable to become an ecological adaptive type for healthy cultivation of stichopus japonicus. Since the sea urchins are cold water species, the sea urchins are not suitable for cultivation in seawater ponds with high water temperature in summer.
Further, in S2, the macroalgae is ulva, cladophora, or enteromorpha.
Further, in S1, the stichopus japonicus pond is a pond in which stichopus japonicus offspring seeds are put.
Furthermore, the putting process of the stichopus japonicus offspring seeds is as follows:
and (3) putting the stichopus japonicus seedlings into the stichopus japonicus pond in spring every year when the water temperature is 10-16 ℃.
Furthermore, the stichopus japonicus offspring seed specification is 300 heads/500 g, and the throwing density is 180-250 kg/hm2。
The invention has the beneficial effects that:
1. the method of the invention uses the echinus intermedia as an ecological adaptive variety, and efficiently utilizes the ecological synergistic culture technology of the natural productivity of the stichopus japonicus pond culture system in the low temperature period, can efficiently utilize the natural baits of the water body, and can obtain the echinus intermedia with high survival rate and higher growth speed while improving the economic benefit of the stichopus japonicus pond culture system, thereby improving the culture efficiency.
2. The invention selects the sea urchin Strongylocentrotus intermedius with high nutritive value and rapid growth based on the principle of feeding property and ecological niche, carries out ecological cultivation of small-specification seedling under the condition that the water temperature of the sea cucumber culture pond is not more than 25 ℃, not only can fully utilize large algae such as ulva, cladophora and the like in the pond as high-quality bait of the sea urchin, converts high-level natural productivity in the pond into sea urchin seedling with high survival rate and rapid growth speed, greatly improves the economic benefit of the sea cucumber culture pond, but also can avoid the outbreak of the large algae, reduces the culture cost generated by large amount of artificial weeding, and simultaneously does not use herbicide, optimizes the ecological environment and water quality conditions of the pond, organic large debris in excrement of the sea urchin after the sea urchin ingests the algae becomes an important food source of the sea cucumber, so that the energy flow and material circulation of the sea cucumber culture pond are well operated, and the ecological environmental protection and environmental protection of the sea cucumber culture system are formed, A new sustainable culture mode with improved quality and efficiency.
