Development of Genetically Tagged Bay Scallops for Evaluation of Seeding Programs

The fish in our experiment grew fastest when fed the prepared diets. However, because hand-feeding hundreds to thousands of juvenile toadfish is not practical, we are attempting to refine the feeding techniques to reduce or eliminate this time-consuming step. The 4and 5-week-old toadfish have begun foraging, indicating that the food presentation may only be needed during the first month. ariations in each tank (water chemis ry, ambient light, vibration) ere not examined and may have subtly influenced individual fish. inally, the en rgy expenditure (foraging vs. "hand" feeding) etween the liv and prepared di ts will need to be addressed in the We thank the Waquoit Bay National Estuarine Research Reserve for use of their facilities.
