Overview of Aquaculture Background, Career & Business Opportunities, Fish Culture Phases, and Fish Identification Presented by: Borcelle Group AQUACULTURE AND FISHERIES
WHAT IS AQUACULTURE? Aquaculture is the practice of breeding, raising, and harvesting aquatic organisms — including fish, shellfish, and aquatic plants — under controlled or semi-controlled conditions. Unlike traditional fishing, aquaculture actively manages the growth of aquatic life, making it a vital science and industry in today's world. Aquaculture & Fisheries: As natural fish populations face increasing scarcity due to overfishing and environmental changes, aquaculture plays a critical role in supplementing the natural fish supply. It helps meet growing food demands, supports local economies, and promotes sustainable use of aquatic resources. Key Terms: • Aquaculture — controlled cultivation of aquatic organisms • Fisheries — the industry of catching, processing, and selling fish and other aquatic life
EARLY HISTORY OF AQUACULTURE 2953 B.C. – China: The earliest recorded fish culture began under Emperor Fu Hi, who is credited with pioneering carp farming in ancient China. 1st Century A.D. – Rome: Romans cultivated fish as delicacies in specially built ponds, reflecting the early importance of aquaculture in Mediterranean culture. 1590 – England: Leonard Mascall published his "Book of Fishing," one of the earliest written guides on fish cultivation and pond management. 1792 – USA: Squire Caroll's diary documented the first rearing of goldfish in America, marking a significant milestone in ornamental aquaculture. Japan: Kokichi Mikimoto pioneered pearl oyster culture, revolutionizing the aquaculture industry and establishing Japan as a leader in marine cultivation. These milestones show how aquaculture evolved across civilizations, laying the foundation for modern fish farming practices worldwide.
AQUACULTURE IN THE PHILIPPINES Malay emigrants introduced the first fishponds to the Philippines. The towns of Navotas and Malabon in Bulacan became the pioneering centers of the fishpond industry, establishing the foundation of Philippine aquaculture. Dr. Pio Valencia and Talava played key pioneering roles in advancing fish farming. Scientific fish farming officially began in 1940 with the start of milkfish (bangus) culture, marking a turning point in Philippine fisheries development.
LEADING AQUACULTURE RESEARCH CENTERS SEAFDEC ICLARM CLSU Freshwater Aquaculture Center The Philippines is home to world-class aquaculture research institutions that drive innovation, education, and sustainable fisheries development. These centers provide training, research, and technical support to fish farmers and the industry nationwide. Southeast Asian Fisheries Development Center — Located in Tigbauan, Iloilo. Conducts regional research on aquaculture technology, fisheries management, and training programs for Southeast Asian nations. International Center for Living Aquatic Resources Management — Based in Makati City. Focuses on improving aquatic resource management, genetic research, and global fisheries sustainability initiatives. Central Luzon State University's Freshwater Aquaculture Center — Located in Nueva Ecija. Specializes in freshwater fish culture research, fingerling production, and training programs for local fish farmers.
GOVERNMENT SUPPORT FOR AQUACULTURE Model Fish Farms Hatcheries & Fingerling Distribution Technical Assistance Programs The Philippine government actively supports aquaculture development through nationwide programs. These initiatives empower local fish farmers, boost production, and promote sustainable fishery practices across the country. The government established model fish farms nationwide to demonstrate best practices in aquaculture. These farms serve as learning centers for local farmers, showcasing modern and sustainable fish farming techniques. Government-operated hatcheries and nurseries produce and distribute fingerlings to fish farmers at low or no cost. This ensures a steady supply of quality fish stocks to support grow-out operations across the country. Trained fishery technicians and extension workers provide hands-on technical assistance to fish farmers. Programs include training on fish health management, water quality monitoring, and proper aquaculture systems management.
TYPES OF AQUACULTURE SYSTEMS Pond Culture: An aquaculture system that uses an enclosed area of water surrounded by an artificial dike or embankment. Fish are raised in controlled ponds where water quality, feeding, and stocking density can be managed. Ideal for freshwater species like tilapia and milkfish. Cage Culture: A system where fish are reared inside a fully enclosed cage or net submerged in a natural body of water such as a lake, river, or sea. Water flows freely through the cage walls, providing natural oxygenation while keeping fish contained for easy management and harvesting.
TYPES OF AQUACULTURE SYSTEMS Raceway Culture: A flowing water system where fresh water continuously passes through long, narrow channels or tanks. Fish are raised at high densities as the constant flow supplies oxygen and removes waste. Ideal for fast-growing species like trout and salmon in areas with abundant clean water sources. Recirculating Aquaculture System (RAS): A land-based, closed- loop system that treats and reuses water continuously through filtration and aeration. Allows year-round production in controlled environments regardless of climate. Highly efficient and environmentally friendly, minimizing water use and waste discharge.
PHASES OF FISH CULTURE Broodstock Selection & Breeding — Healthy adult fish (broodstock) are carefully selected based on size, health, and genetic traits. They are conditioned in special tanks and induced to spawn, producing fertilized eggs that will begin the next generation of fish. Hatchery Operations — Fertilized eggs are incubated in controlled hatchery tanks. Water temperature, oxygen levels, and cleanliness are closely monitored. Eggs hatch into larvae, which are fed microscopic food (algae, zooplankton) until they grow into fry ready for the nursery phase.
