The main objectives of this study were to study the parasitic infestation of Lernaea cyprinacea in 4 cyprinids from the Choghakhor Lagoon, Chaharmahal - Bakhtyari Province, west of Iran. A total of 180 cyprinids including Cyprinus carpio (n=101), Carassius auratus (n=47), Capoeta aculeata (n=10) and Alburnus alburnus (n=22) caught, and were studied for Lernaea cyprinacea infestation. Prevalence...

alburnus chalcoides , caspian shemaya, is found in the river systems of the aral, black and caspian sea basins and is an economically valuable cyprinid from the southern caspian sea. this species has been reported as near threatened species in this basin due to damming, over and illegal fishing, destruction of its spawning grounds and water pollution. the caspian shemaya is an important species...

the lernaea parasite was reported in alburnus hohenackeri kessler, 1870, collected from the char-nimeh (or chahnimeh) lake, eastern iran. three fishes were infected with l. intestinalis having 3 to 22 parasites increasing with fish size. the maximum and minimum of parasite lengths were 138.02 mm and 24.54 mm respectively. the prevalence, mean intensity and abundance of infection by plerocercoid...

We compared the repeatability, reproducibility (intra- and inter-measurer similarity), separative power and subjectivity (measurer effect on results) of four morphometric methods frequently used in ichthyological research, the "traditional" caliper-based (TRA) and truss-network (TRU) distance methods and two geometric methods that compare landmark coordinates on the body (GMB) and scales (GMS)....

This paper reports the results from mobile hydroacoustic surveys carried out between 1994 and 2018, to assess fish stocks in four impounded reaches, covering 19.8 km of River Thames, England. The data are complemented with electric fishing boom boat results, collected at same study reaches time periods. Hydroacoustic used inter-calibrated dual split-beam scientific echosounders, transducers bea...
