General description of research on brown trout population genetics:

Major aim of our research is to study the genetic variability present in brown trout populations of Turkey. Samples are collected from three different geographic regions of Turkey: (1) Western Meditterrenean Coast (many populations have been lost in the last 5 years), (2) Central Anatolian Lake (population of the lake is claimed to be an endemic one), (3) Eastern Black Sea Coast (individuals are from a river which also hosts anadroumous population).

Presence of unique alleles/ haplotypes are searched and heterozygosity levels of the population have been determined to develop conservation strategies for Turkish brown trout populations. Non of these populations received fish from hatcheries.

Protein electrophoresis, mtDNA PCR-RFLP are the tools used in our studies.

List of projects (brown trout) for the past 3 years:

 

Study #1
Researcher: A. Murat Kocabas (Ph.D. student), Ebru Plan, Füsun Gezgin (MSc. students), InciTogan.
Source of project funding: State Planning Organization, The Scientific and Technical Research Council of Turkey, Middle East Technical University.
Topic: Genetic population structure and diversity, phylogeography.
Objective: To determine the genetic structure of Western Meditterenean, Eastern Black Sea Coast and Central Anatolian Lake populations.
Design: From each water shed at least 3 locations are studied.
Methodology: Allozyme electrophoresis, mtDNA-RFLP.
Trout population: Resident populations.
Origin of samples: Turkey, Black Sea Basin, Mediterranean Basin, Lake Abant (Salmo trutta abanticus).
Status: Started in 1997, going to be finished in 1999.
