摘要

Performances of sunshine bass, the hybrid of female white bass Morone chrysops X male striped bass M. saxatilis, were compared between fish reared in round and rectangular cages in ponds, between fish reared in round and rectangular indoor tanks equipped with biofilters, and between fish reared in ponds without confinement and in rectangular cages in the same ponds. Fish weights at start were 100 +/- 5 g, and trials lasted 108 d. Measurements were in terms of density equivalence for cage-cage and tank-tank comparisons and numerical equivalence for cage-pond comparisons. Survival was 100% in all culture units. Mean growth rates in round and rectangular units were similar (2.5 and 2.6 gld in cages; 2.3 and 2.4 g/d in tanks). Fish grew better in open ponds (2.9 g/d) than in cages in the same ponds (1.4 g/d). Growth and survival of fish in all systems were comparable to reports for palmetto bass (striped bass female x white bass male) and for striped bass.
