1, strictly control the culture environment: this is completely different from the wild environment, effectively avoiding puffer fish from ingesting food containing toxins. Wild puffer fish contain toxins because they eat algae containing tetrodotoxin. Under the condition of artificial culture, the food source of puffer fish is strictly controlled to ensure that they will not come into contact with these toxic algae, thus greatly reducing the accumulation of toxins in the body.
2. Improvement of genetics and gonad development: By changing the food source and breeding conditions of puffer fish, scientists have successfully optimized the genetics of puffer fish and promoted its gonad development. This not only contributes to the healthy growth of puffer fish, but also helps to reduce the production and accumulation of toxins in the body.
3. Use special artificial feeds: These feeds have been carefully developed and prepared, and do not contain microorganisms that cause tetrodotoxin production. By feeding these special feeds, it can be ensured that puffer fish will not ingest toxic substances in the growth process, thus maintaining its non-toxic or low-toxic state.
