Methods of measuring feed digestibility in the green abalone (Haliotis fulgens)
Various methods of calculating feed digestibility in the green abalone were compared. The total fecal collection technique was evaluated by comparing it with two different marker methods, one external (chromic oxide) and one internal (acid-insoluble ash). To obtain this information, a funnel-shaped...

| Sumario: | Various methods of calculating feed digestibility in the green abalone were compared. The total fecal collection technique was evaluated by comparing it with two different marker methods, one external (chromic oxide) and one internal (acid-insoluble ash). To obtain this information, a funnel-shaped digestibility chamber was designed. All the chambers (experimental units) were suspended in a square tank (200-1 capacity) containing aerated seawater and with airflow and temperature kept constant (0.5 l/min, 19 +/- 0.5 degreesC). Two abalone (2 years old |
