There are many reasons. Many believe that native fish have a right not to go extinct for economic reasons. In fact, enough people think this is federal and state law. In addition, many native fish support human needs, such as providing food, recreational opportunities, future medical options, economic well-being, or purely aesthetic value. In species, the benefits to humans are clear. Our recent study on scalpin provided an idea to shed light on the debate. The sculpin is a small (up to 10 inches) bottom-dwelling freshwater fish, and he is one of California's most abundant native fish schools. Most Californians are unfamiliar with these fish. Due to their small size, general abundance, and general reluctance to take hooks, bullheads have been largely ignored. But this oversight helps make them special. Because they were neglected, their history reflects the natural history of California's waterways. By studying native fish such as bullheads, we can learn which freshwater systems were historically connected/separated and how long ago it was. If only he could glean so much knowledge from one group of species (sculptor), imagine what information is hidden in the DNA of dozens of other native species in the state. And with all the changes we're making — dams, aqueducts, reservoirs — California's native fish are becoming increasingly vulnerable. Besides risking loss, it shows that the well-being of some of our vital freshwater ecosystems may not be stable. Indeed, there is enormous global potential for farming and harvesting native fish to provide livelihoods and contribute to global food security. Below, we will highlight several case studies from different regions to provide investors, policy makers, and other stakeholders with new insights to redefine their perspective on farmed species selection. The researchers also found that while these exotic species increased fish production, locals caught more fish, reducing the total value of the catch and thus reducing overall income. I also discovered that Local fishermen caught less local fish for better prices. This seems to be favored by local customers. Worryingly, the study found that fishermen are increasing their catches to compensate, which could further increase fishing pressure on native species. is also explained. Native small fish are often the first to be overtaken or eaten away by non-native species. These small aborigines play a surprisingly large role in ensuring access to animal protein and micronutrients in rural communities, as detailed in the example of India. For example, the Indian Inland Fisheries Institute (IFSI), a study conducted by the International Community of Fisheries Workers Assistance (ICSF) shows that small native fish species are important to the livelihoods and food security of underclasses across India. Access such species are caste-free and accessible to everyone, even in most privately owned paddy fields. Another notable advantage Vivekanandan pointed out at an IFSI-sponsored workshop was that the catching, farming, processing and marketing of small native fish is mostly done by women, giving them the opportunity to become self-sustaining feed. This women's empowerment potential should also be promoted in small-scale farming of landraces. Brazil's tendency to farm native fish is a matter of local practice. As a result, almost all native fish species produced locally are also consumed locally. With fewer intermediaries, these shorter supply chains offer less risk and higher returns for farmers compared to far-flung overseas markets.
