Genetic identification of fish eggs by species-specific DNA markers for use in stock biomass assessments and detection of commercial fraud

Objective

Objectives:
The main objective is to improve a fisheries independent method of fish spawning stock biomass estimation by developing PCR based methods for the accurate identification of the early stages of the eggs of 13 commercially important marine species: Trachurus trachurus, T. mediterraneus, T. picturatus, Macrorhamphosus scolopax, Scomber scombrus, S. japonicus, Gadus morhua, Melanogrammus aeglefinus, Merlangius merlangus, Merluccius merluccius, Merluccius senegalensis, Lepidorhombus whiffiagonis and L. boscii.

The species of each group show overlapped distributions and spawning period and their eggs can be confounded in plankton surveys. Probes will be developed for the following species for commercial fraud identification: Merluccius capensis, M. bilinearis, M. hubbsi, M. gayi, M. australis, M. australis polylepis and Macruronus magellanicus. Results and Milestones: Adult samples of all the studied species have been collected.
