Abstract

|
|
Adhesive membranes in the oocvtes of four loach fishes of Korea were investigated by light and electron microscopes to clarify the structural characteristics among the species. In the vitellosenic stage the adhesive membranes of oocvtes could be classified into two forms as follows: 1) fence-shaped form of Nemacheilus yoni and 2) non-adhesive membranous form of Misgurnus anguillicoudotus, M. Mizolepis, and Lefuo costuto. The adhesive membranes of oocvtes in the loach fishes showed a species specificity with reference to their habitats and spawning properties.
