Abstract


Patterns of the 16S rRNA gene obtained in 8 and 12% acrylamide gels by the SSCP (Single Strand Conformation Polymorphism) method were different for various marine fish species (Macrorhamphosus scolopax, Scomber scombrus, Lepidorhombus boscii, L. whiffiagonis, Trachurus trachurus, T. mediterraneus, Molva molva, Merluccius merluccius). SSCP patterns of this gene were employed to successfully identify formaldehyde-fixed eggs of different species (Merluccius merluccius, Scomber scombrus, Macrorhamphosus scolopax and L. whiffiagonis) in plankton samples. The advantages of SSCPs in comparison with current genetic methods of egg identification are based on their technical simplicity and low price. The application of the PCR-SSCP methodology is proposed for routine genetic analyses in plankton surveys.
