Molecular identification of pelagic fish eggs with oil globule.

Molecular biology reports - 20 Jan 2026

Abstract excerpt

BACKGROUND: Marine fish eggs exhibit transversal morphological characteristics that complicate their identification. It is estimated that 75% of pelagic eggs possess oil globule(s). Identifying these eggs provides valuable information about spawning biomass and potential spawning areas for commercially important and threatened species. Molecular markers, such as the FISH (COI gene), enable a precise...
