Description
Summary:Swim bladder malformation is common in both larvae and later life stages of cultured striped trumpeter Latris lineata. This study used histology and gross morphology of whole larvae to describe the progression of abnormal development that proceeded initial liquid dilation of the primordial swim bladder. In addition, radiography was used to compare swim bladder morphology of cultured juveniles with wild-caught specimens. The histomorphology of the swim bladder prior to lumenal dilation was typical of transient physostome larvae reported in the literature. A distinct swim bladder lumen present in larvae between 5.2–5.7 mm standard length (SL) was assumed to be liquid dilated and coincided with mouth opening. Initial gaseous inflation was first apparent when larvae attained 5.7–6.2 mm SL, after the resorption of the yolk sac and oil globule and the onset of first feeding (
