On the factors affecting the abundance and distribution of the red bandfish(Cepola macrophthalma)in the Western coast of Greece (Patraikos, Korinthiakos Gulfs and Ionian Sea)

Abstract

Abstract A stepwise multiple linear regression model was used in order to examine the influence of environmental factors on the abundance of the red bandfish (Cepola macrophthalma), a bottom dwelling organism, in the Patraikos and Korinthiakos Gulfs and the Ionian Sea, Western Greece. Samples were collected in June 1985. It was found that 95% of the variation in the abundance of the red bandfish in that area is attributed to the combining negative effect of bottom temperature and salinity and the positive effect of depth. The exact form of the relationship was: log C=449.75–17.12 log T‐110.69 log S + 1.09 log D. The strong influence of these abiotic factors on the abundance of the red bandfish, predicted by the model, is found in concordance with behavioral and ecological information on the red bandfish from the Northeast Atlantic, as well as with data on its distribution in the Greek Seas.
