Introduction

The wonderful resources of our rivers, seas, and lakes not only provide recreational activities for the soul, but they have also provided important food in the form of fish for thousands of years. Concerns are growing about a seemingly endless supply of fish being in short supply. This may be due to pollution and the use of modern technology in fishing methods. In an attempt to address this problem, aquaculture, or the science of growing fish in "fish farms," is gaining popularity, combining freshwater and saltwater fish. Both fish are major contributors to supermarket freezers. In 2010, the annual catch of wild and farmed fish reached 149 million tonnes. Over 90% of the world's freshwater fish are caught in developing countries, providing an important source of protein and livelihood for millions of poor people. Eating at least two servings of fish per week, especially fatty fish, is recommended as a strong preventive measure against cardiovascular disease. Although marine fish are known to contain mercury, eating fish is still considered beneficial. Fish oil reduces the inflammatory symptoms of autoimmune diseases such as rheumatoid arthritis and psoriasis. Most importantly, their fat content does not clog arteries like highprotein sources like pork, beef, or lamb. In addition to hearthealthy fats, fish is also an excellent source of high-quality protein. Fish contains "heme iron" which is easily absorbed by the body.

Discussion

It also contains thiamine, niacin, vitamin B6, vitamin B12, and vitamin D, along with calcium. However, recent research suggests that the advice to eat two servings of fish per week should be changed to eating two servings of saltwater fish per week. And serum levels of DHA fatty acids appear to be unaffected. Freshwater fish are low in healthy omega-3 fatty acids, but are mostly low in fat and high in protein, making them a nutritious option for lunch or dinner. A serving of freshwater fish provides 30% of the reference adult intake.

The sculpin is one of these participants, along with certain bacteria, aquatic plants, aquatic insects, and other native freshwater fish species. Once you start removing parts of the system, the original system will eventually collapse. Of course, the tower can be fixed even if the parts are removed. But removing too many will eventually causes the tower to collapse. Also, how strong is the tower if you lose a part and try to replace it with a replacement? Native freshwater fish and the ecosystems that support them are important.

Conclusion

I'm not saying we should stop everything to save these fish. As we move forward, we are simply considering the importance of fish in our water management plans. Eventually, increased human prosperity will cause them to decline. An important aspect of including local species and breeds is maintaining genetic diversity around the world. The aquaculture sector is still very diverse today, with over 600 species farmed. However, with the development and further specialization of this field, the number of farmed species and the genetic diversity within those farmed species is expected to decline rapidly. Similar to the animal husbandry sector, where only a handful of species are still farmed, and many animal species and local breeds are extinct and lost forever.
