K. E.: Glossogobius ankaranensis, a new species of blind cave goby from Madagascar (Pisces:
Gobioidei: Gobiidae). pp. 25-28.
A new species of cave-adapted goby,
glossogobius ankaranensis, is described from a subterranean river in the
Ankarana massif in northern Madagascar. The only other hypogean fishes from the
island are two species in the family Eleotrididae from the south west of the
country. It is most probably related to the widespread epigean and euryhaline Glossogobius
giuris (Hamilton, 1822).
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.
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.
