With the development of science and technology, pollution problems are becoming more and more serious, what effect most is the aquaculture.
With the development of our world, and since the second industry revolution, our new world has been polluted seriously, especially the ocean and our habitat, there are a lot of issues that need us to take care, if we do not do something to solute these problem, our world will be worse and worse.
The most part of our planet is ocean, so there are a lot of people who are living on aquaculture, but now, the pollution caused the ocean issues and habitat damage, these people will lose their job or even lose their life because they need to fill their stomachs with some foods which are from the ocean. So the aquaculture will be considered as their life.
In today’s article, we are going to talk something about how the ocean issuers and habitat damage effect on aquaculture.
In some parts of the world, there are still a lot of people who are practicing fish farming, nowadays, in the U.S., half of the seafood will be eaten so that it can meet the demand of growing global.
There are many reasons that will impact fish farming, such as the species being farmed, the methods used and where the farm is located, these operations will cause habitat damage, disease, escapes of farmed fish and the use of wild fish as feed if we can not use good practices.
Coastal habitats will provide food and protection, so it is important for wild plants and animals, especially the fish. If there is no such a coastal habitat to protect these fish, they will never mature and venture to sea.
The water which is from farms that are open to the environment or that divert wastes and chemicals into adjacent water bodies can pollute the habitats. So some fish farmers want to create a closed systems to manage wastes to protect the habitat they are sited in. It will come true by filtering the water in the ponds and composting wastes, in this way, this system will help farmers keep the fish away from neighboring waters.
The genetic makeup of their offspring after escapees breed with their wild counterparts will be less suited to surviving and thriving in the wild. Besides, the harmony of the ecosystem will be disrupted when they escape as invasive species.
Millions of tons of wild fish are caught and processed into fish meal and fish oil almost every year, such as sardines and anchovies, they are used to make feed for farm-raised species. Salmon is the most popular farmed fish in the world, which require over a pound of wild fish for every pound of weight they gain.
Like catfish and tilapia, they are not carnivores, which can be raised on diets with very little or no fishmeal or fish oil. Some animals feed by filtering plankton out of the water such as shellfish, they do not need any supplemental food, like mussels and oysters.
Some people take large numbers of fish from the wild and grow them for eventual sale instead of raising them from eggs, so these farms will rely on wild populations. Young eels will be caught and raised, then supply unagi to sushi bars.
With the rapid growth of aquaculture, what urgent is the careful oversight by farms and farming systems which require innovative solutions, so we need management agencies, lawmakers, researchers, NGOs, and importantly, the farmers themselves to work together.
We can use improved monitoring and treatment of waste water from fish farms to reduce pollution with reporting the type and quantity of the chemicals and drugs the farmers use. In this way, we can improve transparency of regulations.
Because aquaculture operations often occur near sensitive environments, the protection of habitat need to be legislated, which is much more important. The introduction of non-native species should also be limited, since they will impact natural ecosystems when they escape.
Besides, the data like feed and chemical use, habitat and effluent management, escapes and diseases should be collected, it is important to assess fish farming’s environmental impact and sustainability and essential for producers and governments.
With the development of industry, some industrial products appear in our daily life, such as steel pipes, a lot of steel pipes cross under ground, they may be the most useful tool to transport water in our daily life, on the other hand, it also can be convenient for waste water to transport to the ocean.
So the ocean issues and habitat damage will effect our aquaculture, it is the most important thing that fish farm rely on, we must protect it and make our world better and better.
