Hello, today we will take a look at the matters that need to be paid attention to in shell farming. For some friends who are located in coastal or inland lake areas, shell farming is definitely a good choice. However, it is not an easy task to breed high-quality shell products, and we need to pay enough attention and attention to all aspects. Now, let's learn about the precautions of shell farming!
Shells, also known as bivalves, are benthic marine or freshwater invertebrates. Common species include oysters, clams, mussels, etc., which are rich in nutrients such as calcium and phosphorus.
As an important aquaculture industry, shell farming is distributed all over the world. China is a big country in shellfish farming and has a long history of aquaculture.
Shells need a good water quality environment to grow, and the pH value is suitable for 68-8.7. Salinity in 5-35. Also pay attention to the content of pollutants such as heavy metals in the water body.
Different species of shells have different requirements for water depth, generally speaking, pond culture 1-2 meters is better, marine aquaculture water depth 3-10 meters is appropriate.
Shells generally prefer slightly hard or semi-hard substrates, such as sediment, gravel, etc. Substrates that are too soft or too hard are not conducive to their growth.
Warm and humid climates are most suitable for shell farming, with the optimal water temperature range of 15-30 and below 10 or above 35 will affect their growth.
You can harvest natural shell seedlings by yourself, or you can buy artificial seedlings from professional seed farms. It is necessary to ensure the quality of seedlings to ensure the effect of later breeding.
If artificial seedling raising is adopted, it is necessary to build cement pools, aeration equipment and other supporting facilities to provide a good cultivation environment for seedlings.
In the process of raising seedlings, it is necessary to scientifically control the water quality, feed an appropriate amount of nutritious bait, and remove the silt at the bottom of the pond in time to ensure the healthy survival of the seedlings.
Intensive enclosure culture in artificial or natural ponds, with simple facilities and convenient management, is a common breeding mode.
Cage culture is set up in waters such as bays or inland lakes, which have a controllable density and are easy to harvest, but the investment in facilities is high.
The use of natural sea areas and tidal flats or deep-sea areas for aquaculture is suitable for large-scale operation, but it is greatly restricted by the natural environment.
Young shells can be fed concentrated microalgae species, and adult shells prefer concentrated shellfish fertilizer or compound feed.
According to the breeding density, water temperature and other factors, the feeding amount and feeding frequency should be reasonably controlled to prevent waste and pollution.
It is necessary to clean the sludge at the bottom of the pond regularly, maintain the circulation of the water body, and change the water in time to replenish fresh seawater or fresh water. It is also necessary to control the reasonable range of various water quality indicators.
Common shell diseases include shell deformation, slow growth, decay, etc., and insect pests mainly include shell predators such as sea insects and sea rats.
Paying attention to feeding hygiene and maintaining a good water quality environment are the key to preventing shell pests and diseases. When the disease occurs, it is necessary to administer medicine or manually kill and treat it in time.
Generally, the shells are harvested when they reach a certain size, and they can be captured one by one by hand, or they can be mechanized with equipment.
The fresh shells are cleaned to remove fishy impurities, and then processed and processed by killing, peeling and other processing procedures.
The flesh and shell of different varieties of shells have a wide range of edible and industrial processing value.
Shell products are highly favored in the market, with high yields and unit prices, as long as the scale is moderate and the management is in place, the benefits are considerable.
The development of shell farming can create local jobs, promote the development of related industries, and promote social and economic prosperity.
With the improvement of people's living standards, the demand for seafood products is increasing day by day. It is foreseeable that the shell farming industry will have broad development prospects in the future.
As a sunrise industry, shell farming has brought us a rare opportunity for development. But at the same time, we also need to pay enough attention to the breeding process, whether it is environmental selection, breeding mode design, or post-management and processing, all need to be strictly controlled throughout the process, which can ensure that shell farming achieves ideal benefits. It is hoped that through the above introduction, you will be able to fully understand the requirements of shell farming and lay a solid foundation for successful entry into shell farming.
Why should you choose shell farming? Shells are rich in nutrition, have strong market demand, and have high economic value, and are a sunrise industry with broad prospects.
What kind of environmental conditions are needed for shell farming? Shells need suitable water quality conditions, water depth, substrate and climatic environment, and different varieties have different environmental requirements.
What are the main modes of shell farming? Common shell culture modes include pond culture, cage culture and marine culture, etc., and the appropriate mode can be selected according to the actual situation.
How should shell farming be managed? It is necessary to scientifically feed the bait, control the water quality, prevent diseases and insects, and control the quality of the products in the harvesting and processing links.
What are the economic prospects for shell farming? At present, the market prospect of shell products is good, as long as the management of all links is done, shell farming can create considerable economic benefits.
