17 FISH 336 Introduction to Aquaculture Define Aquaculture: The rearing or farming of aquatic species under controlled or semi-controlled conditions and is equivalent to underwater agriculture. Farming also implies individual or corporate ownership of the stock being cultivated.

18 What Are The Aquaculture Species? A Huge Number ~800 Algae - unicells & macrophytes Higher Plants (watercress) Echinoderms (sea cucumbers, urchins) Molluscs (bivalves, snails, octopus) Crustaceans (shrimps, crabs, crayfish) Chordata (finfish - > 200 species) Reptiles (alligators, snakes, lizards) Amphibians (frogs)

19 FISH 336 Introduction to Aquaculture Aquaculture has an ancient history - but it has lagged far behind terrestrial Agriculture. The recent explosion in Aquaculture is largely due to escape from dependence on natural production of the seed for most species. In freshwater - 60% all production is farmed, while in marine waters < 1% fish production is farmed

20 FISH 336 Introduction to Aquaculture ~50% of Food Fish Come from Aquaculture Fastest Growing of all Food Sectors 51.7 Million metric tons, $78.8 Billion Alaska 2.46 Mmt (1.7% of total) Annual; Growth Rate ~7% 2.9 Billion People Rely on Aquaculture FAO 2006

21 Percent Total Dietary Protein Derived from Fish: by Region Region % Pop n % 1. No America ~ 7 % 530M 7.5% 2. Europe ~ 11% 740M 10.5% 3. Africa ~ 17% 995M 14% 4. Asia ~ 26% 4.15B 60% 5. So America NA 385M 5.5%

22 US 2007 Aquaculture Values Catfish Molluscs Trout Other Fish Baitfish $455.4 M $243.0 M $210.6 M $187.7 M $40.3 M

23 World Tilapia Production

24 2006 FAO Reports China Produced 67% Aquaculture Biomass 49% of Aquaculture Value Worldwide Aquaculture Trade is 2x the Worldwide Trade in Meat and Poultry 800 Species under Aquaculture Worldwide

25 US Aquaculture Imports Shrimp Salmon Canned Tuna Fresh & Frozen Other Canned $4.1 Billion $1.6 Billion $661 Million $12.1 Billion $1.6 Billion

26 MT(Million) World Fisheries Production Aquaculture Capture Total Year

27 Alaska s Strengths & Opportunities 1. Wild Natural Product 2. Sound Fisheries Management 3. Omega 3 Fatty Acids 4. Vitamin D 5. Whitefish Strong Tilapia Coming on 6. Wild Salmon now Niche Market Item 7. No Effective Substitutes for: Halibut, Sablefish, Crab.

28 Alaska: Weaknesses & Threats 1. Inconsistent (Seasonal) Supply & Quality 2. Labor Issues 3. Aquaculture: Salmon, Tilapia, Cod 4. Farmed Industry Keeps Lowering Costs 5. US & Europe: Low Seafood Consumption 6. US: Unwillingness to Pay More for Food
