This is a presentation I gave at the Applied Phycology congress in Galway Ireland in the IMTA session in 2008

1. A pilot scale integrated seaweed ( Ulva lactuca ) & abalone ( Haliotis midae ) recirculation system Deborah V. Robertson-Andersson 1,6 ; Michelle, Potgieter 1 , Joakim, Hansen 2 ; John J.

7. Seaweed tank Pump Gravity feed Abalone tanks Seaweed tank 25 % recirculation 75 % Sea water Over flow

8. Seaweed tank Pump Gravity feed Abalone tanks Seaweed tank 25 % recirculation 75 % Sea water Over flow

20. SO what next….

21. Commercial integrated seaweed abalone system: 50 % recirculation Intake Seaweed paddle ponds Sump Drum filter Abalone tanks Header tank Pump Seaweed harvest point Outlet

22. Feed Quality: Tissue Nitrogen vs. Thallus Colour Tissue protein content (mg N.g)

23. Food Quality: Humans

24. Food Quality: Humans Taste test questionnaire Dear taste tester Thank you for agreeing to be a part of this testing programme. Testing will be done using two taste test approaches: A) A quantitative descriptive analysis B) A difference test (triangle test) The purpose of this test is three fold: 1) To rank you as a tester 2) To evaluate which is the most acceptable abalone diet 3) To compare all the taste samples to a reference smell of DMS This will be done for both cooked and raw abalone.
