THE ABUNDANCE AND SPECIES COMPOSITION OF STURGEON IN THE NORTHERN CASPIAN SEA

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2008
This study was carried out in the northern Caspian Sea on Gidrobiolog vessel in summer 2006 to assess the abundance and species composition of sturgeons. We used bottom trawl (9m) and gillnets with mesh size 60, 110, 250 and 29Omm.

Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla

Journal of Fish Biology, EarlyView.
Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

Standardized Sperm Cryofreezing Technique for Caspian Sea Sturgeons (Huso huso, Acipenser persicus, Acipenser stellatus, Acipenser nudiventris)

Genetics of Aquatic Organisms
Sturgeons, considered `living fossils,` face extinction due to various factors, according to the International Union for Conservation of Nature's Red List. The present study describes a uniform sperm cryopreservation method for the endangered Caspian Sea sturgeon species, which are beluga (Huso huso), Persian (Acipenser persicus), stellate (Acipenser ...

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Studying the manner of sturgeon fishes migration to Gorganrud and Tajan rivers

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1997
One year study was carried out to understand the sturgeon fish’s migration to Gorganrud & Tajan Rivers from September 1993. Two different catching stations were selected in each river with gillnetting method.

Contrasting population genomic structuring of northern pike (Esox lucius L.) in fresh‐ and brackish water environments: Implications for management and conservation

Journal of Fish Biology, EarlyView.
Abstract Understanding the factors that shape population genetic structure is crucial for advancing evolutionary studies and developing effective management and conservation strategies. The northern pike (Esox lucius L.) is a top teleost predator that inhabits fresh and brackish water environments in the northern hemisphere.
