Zusammenfassung

Eine neue Höhlen-Grundel Glossogobius ankaranensis, wird aus einem unterirdischen Fluß des Ankarana-Massivs in Nord-Madagascar beschrieben. Die einzigen  anderen hypogäischen Fische der Insel sind zwei Arten der Familie Eleotrididae aus dem Südwesten des Landes. Die neue Art ist sehr wahrscheinlich mit dem weit verbreiteten epigäischen und euryhalinenGlossogobius giuris (Hamilton, 1822) verwandt.

Klossa-Kilia, E. and I.C. Ondrias: Age, growth and length-weight relationship of brown trout Salmo trutta L. in the upper stream of Acheloos River, Greece, pp. 29-36.

Abstract

The age, growth, length-weight relationship and condition factor (k) of brown trout, Salmo trutta L. was studied in a small tributary of the Acheloos river. Totally 309 specimens were collected. The age group 1+ and 2+ formed the greatest part of the population. The annual growth was estimated with the back-calculation method based on the relationship between scale radius and body length in 101 individuals. The length-weight relationship can be described by the following equations: W = 0.0000266 L2.865 and W = 0.0000322 L2.825 for males and females respectively. The average codition factor (k) ranged from 1.16-1.25 and 1.10-1.21 for males and females respectively.
