Physiological and biochemical parameters for egg quality determination in lake trout, Salmo trutta lacustris

- BiologyFish Physiology & Biochemistry
- 1 May 1999
The relationships between egg viability and ovarian fluid composition, egg physiology and egg metabolism in lake trout, Salmo trutta lacustris, are investigated to obtain biomarkers for egg quality determination and subjective and visual control methods were described to distinguish between batches with viable and non viable eggs.
Minireview: The modes of egg attachment in teleost fishes
- R. Riehl, R. Patzner
- Environmental Science
- 28 February 1998
Oocytes and eggs from teleost fishes are always surrounded by an egg envelope of variable dimensions that is largely responsible for a protective function, whereas the zona radiata externa is used to attach the eggs to the substrate where they are deposited.
Sperm motility of the marine teleosts Boops boops, Diplodus sargus, Mullus barbatus and Trachurus mediterraneus
- F. Lahnsteiner, R. Patzner
- Biology
- 1 April 1998
The spermatozoa of Boops boops, Diplodus sargus, Mullus barbatus, and Trachurus mediterraneus were motile in sea water, and in electrolyte solutions and non-electrolyte solutions with an osmolality of 600–1000 mosmol kg−1, and species-specific parameters which could not be related with the sperm motility behaviour were revealed.
Changes in Morphology, Physiology, Metabolism, and Fertilization Capacity of Rainbow Trout Semen following Cryopreservation

- Biology
- 1 July 1996
Alterations in morphology, physiology, metabolism, and fertilization capacity of the semen of rainbow trout Oncorhynchus mykiss after cryopreservation were investigated and spermatozoa showed intensive signs of swelling of the head and midpiece regions and of the mitochondria in frozen–thawed semen.
Functions of the testicular gland in two blenniid fishes, Salaria (=Blennius) pavo and Lipophrys (= Blennius) dalmatinus (Blenniidae, Teleostei) as revealed by electron microscopy and enzyme…

- Biology
- 1 July 1990
The functions of the testicular gland in two different blenniid fishes, Salaria pavo and Lipophrys dulmutinus, are described by fine structural and enzyme histochemical methods and possible explanations for the reduced testis in L. dalmatinus are discussed.
