  1. TRANSPORTING FISH

  2. TRANSPORT MORTALITY • Poor water quality • Water & ion imbalances • Stress-induced immunosuppression

  3. WATER QUALITY • Temperature • Oxygen • pH/ammonia/carbon dioxide • Total dissolved solids

  4. Metabolic Activity

  5. Dissolved Oxygen Saturation

  6. Dissolved Oxygen and Salinity

  7. Oxygen Consumption

  8. Ammonia Relationships

  9. Ammonia Transport Across Gill

  10. Water and Mineral Transport Fish pump ionsinanddonot drink Fish pump ionsoutand drink Iso-osmotic Salinity 0 g/L 10-12 g/L 35 g/L Freshwater Seawater

  11. Alkalinity and pH

  12. Disease Prevention and Outbreaks

  13. Stress and DiseaseOutbreaks

  14. RULES OF THUMB • Reduce the number of stressors (Know what you are doing) • Reduce severity of stressors (Don’t knock your fish around) • Minimize duration of stressors (Don’t haul fish around the USA!) • Minimize plasma ion disturbances (Use salt) • Minimize increases in metabolic rate (Correct temp., etc.)

  15. Knotless Netting

  16. Knotted Netting

  17. Fish loaded into bag and ready for oxygen “top-off.”

  18. Oxygen injection into bagged fish...will keep up to 24 hrs. (If fish are small and low density!!)

  19. Bagged fish loaded into box for shipping.

  20. Case Study: How to Move Red Drum…or How NOT too!

  21. Healthy? Much better over here!

  22. 7:00 AM Everyone’s here…let’s get started!

  23. “101, 102…” “Gee…This is time consuming!” “I’m hungry, anyone bring donuts??” “Well, he said, then she told him to….” “Was that 203, 204, 205?” “Whose counting these???” 8:02 AM

  24. 10:15 AM Several hours later…still at it!

  25. “Did anyone calibrate the scale this AM?” “Don’t look at me, I thought Becky was supposed to do it?” 11:07 AM

  26. 12:30 PM “Who wants to break for lunch??”

  27. 2:00 PM “Did anyone check the batteries on this thing?”
