SEED RESOURCES OF SHORE BASED AQUACULTURE AND SEA.pdf

Shore-based aquaculture refers to the farming of aquatic organisms in land-based facilities along the coast, utilizing brackish or saltwater ponds, tanks, or pens. This form of aquaculture plays a vital role in enhancing seafood production and reducing pressure on wild fish stocks.

History
Aquaculture is an ancient practice with records of fish culture dating back thousands of years in regions like Egypt, China, and Southeast Asia. The Egyptian brackishwater pond system is considered one of the oldest coastal aquaculture systems, with a history spanning two to three
