Proposed models are two rat strains genetically selected for high (KHA) and low (KLA)
acquisition of active avoidance subjected for escapable or inescapable footshocks. Inescapable
footshocks applied to KHA rats induce escape failures and dexamethasone nonsuppression of the
BHPA axis. In contrast, KLA rats exposed to footshocks demonstrate elevated anxiety and
elevated corticosterone levels, but the learning abilities, and dexamethasone-reactivity of KLA rats
still unchanged. Therefore, the KHA rats exposed to inescapable stress represent the model of
depression, and KLA rats exposed to stress represent the model of elevated state anxiety.
3143.2 Environmental- behavior of C.dubius nutrition in Indian ocean and Oman sea coast,
Armin Kousha, The AZAS University, Iran
The aim of this research conducted in five station of the area on a particular species of tongue
fishes called C.dubius. 236 fishes were studied biometrically during the project. This species
primarily feeds on Bivalve, Polychate, Crustacean fragments, and secondarily on fish eggs.
Statistical calculation showed significant difference among length groups and among different
seasons and proved the hypotheses that it is up to the fish to choose its own prey and that, there is
no different between male and females. The G.I index showed that from September to November,
the amount of nutrition for both males and females is at the lowest level.
