Investigation Of The Selectivity Of Monofilament Gill Nets Used In Carp Fishing (Cyprinus Carpio L., 1758) In Lake Beyşehir, İsmet Balik

Turkish Journal of Zoology

In this study, the selectivity of monofilament gill nets used for fishing carp in Lake Beyşehir was studied. Monofilament gill nets with mesh sizes of 7, 8, 13 and 14 cm were used in experimental fishing between October 1994 and May 1996. From the results, the common selection factor of monofilament gill nets was calculated as 2.922.

The Feeding Features Of The Pike-Perch (Stizostedion Lucioperca) Population In Lake Beyşehir, İsmet Balik Jan 1999

The Feeding Features Of The Pike-Perch (Stizostedion Lucioperca) Population In Lake Beyşehir, İsmet Balik

Turkish Journal of Zoology

The stomach contents of pike-perch (Stizostedion lucioperca) in Lake Beyşehir were investigated. The stomachs of 474 pike-perch were studied between March 1995 and February 1996. 76.6% of specimens had full and 23.4% had empty stomachs. The contents of the stomachs consisted of Gammarus sp. (77.5%), Mysis sp. (14.7%), Chirinomidae (4.3%), pike-perch (2.7%) and others (0.8%). Around 20.9% cannibalism was estimated and it was widespread among individuals with a length of 11-60 cm. In addition, it appears that pike-perch can consume fellow specimens with a mean size of 35.9% of its length.

A Computer Programme For Determining Habitat Preference Based On Dung Frequencies Of Some Herbivore Mammals, İdri̇s Oğurlu, Hakki Yavuz

Turkish Journal of Zoology

The classic approach for habitat preference of big games is to compare dung density in two different site such as in two habitat types and aspects, or in two altitute or slope classes. Whereas, animals select habitats according to all habitat components. Therefore, it must be considered multivariate structure of habitat and importance of each variable of the combination of components. In this study, interaction among habitat components and effects of components more than one were investigated in a conservation area. A computer programme (SR.BAS) was prepared to identify the important components of habitat of herbivore mammals in the area. …

The Changes In Glycogen Levels Of Pimpla Turionellae L. (Hymenoptera: Ichneumonidae) In The Conditions Of Starvation, Feeding, Parasitism And Aging, Deni̇z Akman Şeker, Ati̇la Yanikoğlu

Turkish Journal of Zoology

The changes in glycogen levels depending on starvation, feeding, aging and parasitisation in the mature female of Pimpla turionellae L. (Hymenoptera: Ichneumonidae), which is a biological control agent, have been observed. Glycogen level, which is a major energy source in insects, increased when the females of P.turionellae are fed with 30% honey, but it decreased depending on aging, starvation and parasitism. There was a positive relationship between the glycogen level of an insect and the number of its eggs laid within the host pupae.
