ABSTRACT
Perch sweeper fish with
scientific name Cobitis taenia is one of the Cobitidae family. Since this kind of
fish lives in clean waters and in the high areas of Talar River, it can be an index on water
implution. This survey on the
diet of this specimen is done on two stations (Kaselian and Tajoon) and shallow
and high areas of Talar River in Mazandaran (Southern part of
Caspian sea) and the duration of this survey is from October 2008 till
September 2009. We should mention
that fishing was just done by electro-shocker with voltage 300 V. And this fish after
fishing is fixation in 10% formalin solution.
So 410 perch sweeper fish were examined and the average of
relatively length of gut (RLG) was 17.35 cm. The index of vacated intestine (VI) was calculated 43.35% for all samples. From intense of diet points of view (GSI), the most frequency of
full intestines was considered in summer and spring. On the other hand, the smallness of relatively length of gut index (RLG < 1) shows that perch
sweeper fish’s diet manner is
inclined to herbivority. In the examination of containing of digestive track, overally 10 kinds of
foodstuff were known. Based on amount of this index, 2.67% Chironomidae is known as main bait in all sampling period.
