The effect of rapeseed oil methyl ether (RME) on cladocerans (water flea Daphnia magna Straus) and fish embryos prolarvae (round goby Neogobius melanostomus (Pallas)) is investigated. It has been determined that, with the increase RME content in water, decrease survival rate, fecundity, abundance, biomass population observed, as well rate round fry linear weight growth fry. did not produce any ...

The present study describes for the first time some biological aspects (size composition, sex ratio, length-weight relationship and condition factor) of Ponticola constructor (Caucasian goby) inhabiting Borçka Dam Lake its tributaries from lower Çoruh River Basin located in northeastern Türkiye. Fish samples were caught June 2017 to May 2018 by using trammel nets with various mesh sizes pulsed ...

Waterfalls may affect fish distribution and genetic structure within drainage networks even to the extent of leading evolutionary events. Here, parallel evolution was studied by focusing on waterfall and the landlocked freshwater goby Rhinogobius sp. YB (YB), which evolved from amphidromous R. brunneus (BR). The fish fauna was surveyed at 30 sites in 11 rivers on Iriomote Island, Japan, the geo...

The global spread of invasive species is changing the structure of aquatic food webs worldwide. The North American Great Lakes have proved particularly vulnerable to this threat. In nearshore areas, invasive benthic species such as dreissenid mussels and round gobies (Neogobius melanostomus) have gained dominance in recent years. Such species are driving the flow of energy and material from the...
