Principles of pikeperch (Sander lucioperca) larviculture
Pikeperch (Sander lucioperca) is a species with high nutritional, ecological and commercial values which is endemic in Iran, but its natural stocks are endangered during recent years. Therefore, Iranian Fisheries Organization as the main responsible organization for preservation of aquatic natural stocks of the country planned to stock rehabilitation of this species since 1989. This program had...
متن کاملCoastal and freshwater pikeperch (Sander lucioperca) populations differ genetically in the Baltic Sea basin.
Microsatellite DNA based analysis of the pattern of genetic diversity among three coastal and five freshwater populations of pikeperch Sander lucioperca in the northern part of the Baltic Sea drainage basin indicated marked genetic differentiation between the coastal and lake populations. The F(st) between these population groups was as high as 0.25 and R(st) =0.32. In general, the lake populat...
متن کاملSperm morphology, ultrastructure, and motility in pikeperch Sander lucioperca (Percidae, Teleostei) associated with various activation media
Spermatozoa morphology, ultrastructure, and spermatozoa motility traits were studied in pikeperch (Sander lucioperca) after activation in various media (AM 1 – 45mM NaCl, 5mM KCl, 20mM Tris, pH 8.5; AM 2 – 100mM sucrose, 20mM Tris, pH 8.5; AM 3 – 100mM sucrose, 1mM CaCl2, 20mM Tris, pH 8.5) during a 48-hour storage period. The spermatozoon was acrosomeless and differentiated into a spherical nu...
متن کاملEfficacy of different anaesthetics for pikeperch (Sander lucioperca L.) in relation to water temperature.
OBJECTIVES The objectives of the study were to compare the different doses of clove oil, Propiscin, and tricaine methane sulphonate (MS 222) in relation to water temperature in pikeperch aquaculture. DESIGN For assessment of this experiment 168 fish (10.77 ± 0.59 cm total body length and 7.88 ± 1.74 g body weight) were used. Three different anaesthetic treatments (Propiscin, clove oil and MS ...
متن کاملGrowth and Diet of the Pikeperch Sander Lucioperca (l.) in Two French Reservoirs
The pikeperch Sander lucioperca (L.) is present in numerous French water bodies. However, few studies have focused on the biology and ecology of the species and, as a result, references are lacking to assess its adaptation to lacustrine environments. The growth and diet of pikeperch were investigated in two reservoirs located in southern France. The fish at both sites show similar growth rates ...
