1949 results about "Shellfish" patented technology

Shellfish is a colloquial and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some are found in freshwater. In addition, a few species of land crabs are eaten, for example Cardisoma guanhumi in the Caribbean. Shellfish are among the most common food allergens.

The invention provides a shrimp-fish-shellfish-alga multi-unit culture and aquatic organism regulation system thereof. A shrimp culture zone, a fish culture zone, a shellfish culture zone, a large scale alga cultivation zone, a probiotics and microalga culture zone, a water processing zone and an emergency drainage system are arranged in a closed water circulation culture system, wherein the culture water circulates in different culture and water processing units. As the water circulates in different culture units and is utilized in multiple levels by various aquatic organisms of different trophic level and ecological niche, the system gives the various aquatic organisms full play to the positive bait resource complementarity, prevents the aquatic organisms from directly competing on living space and dissolved oxygen and reduces the mutual damage caused by organic remains and metabolic waste, achieves the 'self-modification' and 'biomanipulation' of the culture environment, enables the environment itself to recover from the pollution in culture process, and decontaminates the seawater culture environment.
