Siberian sturgeon (Acipenser baerii Brandt, 1869) is a suitable species for aquacultural purposes. This study was conducted to investigate the influence of stocking density on blood parameters of cultured immature Siberian sturgeon introduced to Iranian aquaculture systems, in order to monitor crowding stress. Two-year old juvenile fish (weight 607.7±21.49(More)
This study describes morphology and fine structure of the Persian sturgeon (Acipenser persicus) (Acipenseridae, Chondrostei) spermatozoon. The results show that the spermatozoon of A. persicus is differentiated into an elongated head (length: mean±SD: 7.1±0.5μm) with an acrosome (length: 1.2±0.2μm), a cylindrical midpiece (length: 1.8±0.5μm), a flagellum(More)
This study investigated the effect of manipulated photoperiod on haematological parameter in beluga sturgeon (Huso huso). One hundred eight fish (24-month old) were randomly allocated into 18 tanks. Each tank received one of six photoperiod regimes for 73 days: natural photoperiod, 24Light (L):0Dark (D), 16L:8D, 12L:12D, 8L:16D and 0L:24D. Different(More)
The relationship between species and habitat is important in ecosystem-based fisheries management. Habitat suitability index (HSI) modeling is a valuable tool in ecology and can be used to describe the relationship between fish abundance and ecological variables in order to estimate the suitability of specific habitats. In the present study, an HSI model(More)
Impact of bambara groundnut protein isolate (BGPI) on autolysis and gel properties of surimi from lizard fish was investigated. As the levels of BGPI increased (0-3%), breaking force, deformation and retention/ stability of myosin heavy chain (MHC) of modori gel markedly increased (P<0.05). Nevertheless, only 0.25% BGPI increased above parameters in(More)
Concentrations of 11 metals (cadmium, zinc, copper (Cu), vanadium (V), lead, magnesium (Mg), manganese, aluminum, iron (Fe), chromium (Cr), and nickel), and one metalloid (arsenic (As)) were measured in sediment, common reed (Phragmites australis), algae (Spirogyra sp.), and blood worm (Chironomus sp.) tissues of samples collected from the Shoor river.(More)
The DNA breakage has been widely used in ecotoxicological studies to investigate effects of pesticides in fishes. The present study used a fuzzy inference system to quantify the breakage of DNA double strand in Aphanius sophiae exposed to the cypermethrin. The specimens were adapted to different temperatures and salinity for 14 days and then exposed to(More)
