Trisopterus is demonstrated to be monophyletic, including four distinct species: T. capelanus , T. esmarkii , T. luscus and T. minutus . The capelan T. capelanus is resurrected from the synonymy of poor cod T. minutus, and is shown to be morphologically more similar to T. luscus , to which species it is also more closely related, indicated by a phylogenetic analysis presented here. A lectotype is designated for T. luscus . Tri...

There were significant correlations between colour pattern, LDH ‐5*, genotype and certain meristic characters in 59 hybrid trout Salmo , sp. from the Volarja stream, Soca River basin, Slovenia. It is concluded that panmixia between native Salmo marmoratus , and introduced S. trutta , of Atlantic, Danubian and Mediterranean origin had not been reached in this zone, despite the long period of introgression. The result is in agre...

Poly‐and monoclonal antibodies, raised against mammalian membrane‐bound proton pump (V‐ATPase) were applied to the bone‐resorbing cells of Oreochromis niloticus to clarify if osteoclasts of an advanced teleost species display V‐ATPase, a key enzyme in the process of bone resorption. All antibodies labelled cells at known sites of bone resorption, the endosteal bone surfaces surrounding the tooth anlagen. The best results were...
