| 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. |

| 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. |
