Module I Notes: Aquaculture Objectives Food Stock management Restoration Materials (oysters, alligator skin) Recreation Pets Nutraceuticals Other (bait) Overview: Similar to farming. Pipeline: Seedlings → nursery → field (grow-out) Has regulations (licenses/permits) Operation Flow Chart: Broodstock → hatchery → spat/fry, etc. → nursery → grow-out → market. Asia is #1 in aquaculture. (Inland & Marine). Americas → Europe → Africa → Oceania Aquaculture was part of essential living for the poor in the developing world. America is still a major role in the global aquaculture. U.S. is leading global importer w/ 91% Aquaculture Food: #1 Catfish #2 Oysters Salmon Trout Prawns Texas Aquaculture: #1 Catfish Marine Shrimp Striped Bass Red Drum Aquaponics Life Cycle: Clone Incomplete Metamorphosis Complete Metamorphosis Terms: Polar Body: Each of the small cells that bud off from an oocyte. Haploid: Having a single cell of unpaired chromosomes. Diploid: A cell with paired chromosomes. Polyploid: >2 homologous chromosomes. Aneuploid: Containing an abnormal amount of chromosomes. If you can recreate environmental cues, you can activate specific stimuli in your broodstock. IDEAL ORGANISMS: Consider the requirements of your organism. Easy/cheap young Short larval stage Fast growth rate Hardy Size and Age to maturity Consumer Acceptance Good return on investment Exotic Dangers: Need to be needed. Not compete w/ native species No crossing w/ natives No pathogens Live in equilibrium. Module 2: Hatcheries Hatchery: A physical entity where adult animals are bred in order to produce young animals for grow-out... Advantages to creating your own hatchery: Allows genetic manipulations. Biosecurity. Disadvantages: Can add to costs because you're starting from the better. High levels of expertise/skills required.
