Article
In this study, the cumulative influence of male acclimation temperature on sperm quality of the Çoruh trout Salmo coruhensis was compared during the sperm production period. Broodstocks were kept in constant (12.8ºC), and changing (8.4ºC to 12.8ºC) water temperature using well water and stream water until first spawning and sperm quality traits wer...

It would often be practical to starve the cultivated fishes over the weekends, e.g. to save in labour costs. We evaluated the possibility that domesticated juvenile rainbow trout (Oncorhynchus mykiss) could compensate for the lost growth of the 2-day weekend starvation by either hyperphagic response and/or by lower feed conversion ratio, compared t...
Article
In this study, sperm characteristics of Black Sea trout (Salmo trutta labrax) and effects of ions, their concentrations and osmolality of the solution on sperm activation were evaluated. Two different activation solutions with ionic and non-ionic osmolality levels were investigated. After the definition of conditions where osmolality played a ro...

We investigated the effects of growth performance of three plant species parsley (Petroselinum crispum), lettuce (Lactuca sativa) and cress (Lepidium sativum) under the three different lighting sources, Light-Emitting Diode lamp (LED; 200w), High-Pressure Sodium lamp (HPS; 200w) and Fluorescent lamp (FLO; 200w) in an aquaponic system. A total numbe...

The thick-shelled river mussel (Unio crassus) is listed as 'Endangered' on the IUCN Red List of Threatened Species and it is important to culture them for the conservation of natural stocks. Integrating mussels into the freshwater aquaculture system could be an efficient method, because of their filtering ability. In this study, it was aimed to det...

In this study, the quality and reproductive success of wild Black Sea Trout (Salmo trutta labrax) were investigated. In total 32 wild trout (27.3±13.6 g and 13.9±2.3 cm) from the Bıçkı Stream in Kocaeli Province in the Marmara Region were kept in circular fiberglass outdoor flow-through tanks (1.5m ø) at the mean water temperature of 11.8±4.5 °C. I...

Turkey has a rich variety of fish species in its rivers with a total length of 177 714 km. Freshwater fish live in rivers, streams, creeks, dam lakes, natural lakes, wetland areas, etc. The life of migratory fish is threatened by the anthropogenic impact on aquatic habitats. Human activities that disrupt river integrity can be listed as; dam and hy...

Bu çalışmada gökkuşağı alabalığının (Oncorhynchus mykiss) spermine ait motilite ve motiliteye ait kinematik parametrelerin Bilgisayarlı Otomatik Sperm Analiz Sistemi (CASA) ile incelenmesinde farklı lamların kullanılmasının sonuçlar üzerindeki etkisi araştırılmıştır. Motilite ve parametreleri, oda sıcaklığında CEROS II (Hamilton-Thorne, Beverly, MA...

In this study, the effect of the chamber used for the automated analysis of sperm motility and sperm kinematics parameters by CASA was evaluated of rainbow trout (Oncorhynchus mykiss) sperms. The assessment of motility parameters was carried out using CEROS II (Hamilton-Thorne, Beverly, MA, USA) connected to CX41 microscope (Olympus, Japan) at room...

The Hydro development started in the 1960s with building 3 major dams in the upstream section of the Sakarya River. During the 1980s the development of the floodplain sections of the river had its onset. Under these altered conditions Huso huso, Acipenser nudiventris, and Acipenser sturio disappeared from the river until the 1980s but Acipenser gue...

A RESEARCH ON FERTILIZATION SUCCESS AND GAMETE QUALITY PARAMETERS OF ENDEMIC WILD TROUT (Salmo SP.) IN TURKEY
Poster
Full-text available
There are 33 rivers with a total length of 177,714 km on Turkey’s 25 river basin. There are 368 fish species of 31 families, of which 153 are endemic in all inland waters (rivers, dam lakes, nature lakes etc.). Turkey has a rich variety of fish species. The life of migratory fish are threatened by human activities on rivers systems. These human act...

Cryopreservation of sperm and storage for long time in fish has been studied for aquculture species and species of stock’s is currently threatened. Reasons of study on cryopreservation are: to decrease costs associated with keeping live male broodstock, for keeping at conservation of threate species and also using for fertilization of individuals w...
