What is quality from the Hatchery ?Healthy fishWeaned to Pelleted FeedsNo defectsUniform SizePhysiologically appropriate

Healthy FishGoal: Fish should be free of known diseasesApproach SPF hatcheriesGoal: Fish should be protected from potential diseasesApproach:VaccinationNutrition

Fish Weaned to Pelleted DietsGoal: Fast Growth Goal : Uniform SizeGoal: Cost Effective FeedingGoal: Reduce Environmental ImpactsGoal: Healthy FishApproach - Wean fish early and completely in HatcheryApproach - Complete Compound FeedsApproach - No Wet Fish (Trash Fish) Diets

No DefectsGoal : High Product Quality

Approach - In Hatchery Provide Optimal Environmental ConditionsApproach - Provide high quality diets

Uniform in Size

Approach - Start with uniform graded fishApproach - Genetic Selection for Uniform High Growth.Approach - Completely weaned to High Quality Pelleted diets. Goal: Uniform Product at Harvest

Physiologically AppropriateGoal - Excellent Growth and Survival.Perhaps lower OxygenPerhaps stronger currentsApproach - Species Selection Bioenergetics model under conditions likely to be found at site.

Simple Bioenergetics ModelE = G + R + L Where:E is the total energy taken in by the fish from the dietG is the amount of energy going into growthR is the amount of energy used for everything that is not growh (movement, fighting diseases, reproduction, etc)L is the losses due from Feces, Urine and energy to digest the feed (SDA)

Bioenergetics models can be developed for different conditions and species using respirametryFlowDO inCO2 inFlowDO outCO2 outBy measuring the uptake of Oxygen under various conditions you can determine R and predict G
