Abstract:
Hypoxia is an ever increasing threat to aquatic systems. While fluctuating levels of dissolved oxygen (DO) can be a natural phenomenon, hypoxia caused by eutrophication and organic pollution is now considered to be amongst the most pressing and critical water pollution problems in the world, particularly in densely populated regions. The effects of low DO on fishes are an area of great concern and thriving study. Researchers have examined the effects of low DO on fishes from the cellular to community level. The purpose of the current paper is to review the effects of low DO on complex fish beh

There are few parts of the planet where human impacts on riverine biodiversity are more apparent than in monsoonal Asia. Flow regulation, drainage-basin degradation and conversion of riverine wetlands to agriculture have been occurring for centuries, while pollution and over-harvesting have become important in recent decades. Concomitant species loss appears both ongoing and rampant. Uncertainty over rates of loss is imposed by the fact that the extremely rich biodiversity of Asian rivers has not been inventoried adequately. It is nevertheless evident that some taxa are gravely threatened. Spe

Abstract:
Contracaecum is a genus of nematodes belonging to the family Anisakidae, that parasitise many fishes which act as an intermediate or paratenic hosts, while the piscivorous birds and mammals are definitive hosts. A total of 44 third larval stage of Contracaecum were collected from 13 infected freshwater fishes belonging to five different species in different water bodies in Sulaimani Province, Kurdistan Region, Iraq from January to the end of December 2018. In this investigation, 966 fishes were collected including six species of Nemacheilidae, five species of Cyprinidae, three species of Leuci

Abstract:
In all teleost fishes vitellogenesis is triggered and maintained by oestradiol-17beta (E2) and is accompanied by an increase of blood plasma calcium and phosphate. The action of this hormone on calcium metabolism was investigated by treating fast-growing immature juvenile sea bream (Sparus aurata) with coconut butter implants alone (control) or implants containing 10 microg/g E2. Treatment with E2 induced the production of circulating vitellogenin, a 2.5-fold increase in plasma ionic Ca2+ and a 10-fold increase in plasma total calcium, largely bound to protein.

Moss-bags were applied to study the effect of contamination in three standing water bodies in Bulgaria (Kardzhali, Studen Kladenets and Zhrebchevo Reservoirs), the first two with old industrial contamination and the last polluted with short-chain chlorinated paraffins (SCCPs). Fontinalis antipyretica Hedw. collected from background (unpolluted) site was placed in cages for a period of 30 days. The present study examined whether inorganic and organic pollution detected with moss-bags resulted in corresponding differences in molecular, chemical and micromorphological markers.

Global climate change is impacting and will continue to impact on marine and estuarine fish and fisheries. Data trends show climate change effects ranging from fish growth, digestion physiology and performance in marine and freshwater ecosystems. The present study was designed to develop a concept for a cause and effect understanding with respect to climate-induced temperature and salinity changes and to explain ecological findings based on physiological processes. The concept is based on a wide comparison of fish species. The preliminary conclusion can be drawn that warming will cause a shift

Blooms of gelatinous zooplankton can represent dramatic environmental perturbations for aquatic ecosystems. Yet, we still know little about how blooms impact fitness-related behaviours of fish caught within their areas of effect, especially for freshwater systems. Here, we documented the behavioural impacts of freshwater hydrozoan ( Limnocnida tanganjicae ) blooms on a territorial cichlid ( Variabilichromis moorii ), as well as on the wider community of cichlids in a shallow-water rocky habitat of Lake Tanganyika. Compared with non-bloom conditions, V. moorii individuals in the midst of blooms

Abstract:
The ‘La Niña’ phenomenon causes temporary isolation of shallow lakes in rivers with floodplain. Furthermore, as abiotic conditions become more extreme, and intra–interspecific relationships intensify, the risk of local species extinction increases. The Paraná River in South America is a river with an extensive floodplain with many shallow lakes. In these environments, freshwater prawns and many fish species coexist. The aim of the work was to study the interaction between two species of prawns (Palaemonetes argentinus and Macrobrachium borellii) and fishes during ‘La Niña’ phenomenon. Density

The acute toxicity test show that 96h LC50 value of 2,4-DNT to Brocarded carp is 19.67 mg/L. Its toxicity rating is moderately toxic to fish. Based on the result of the acute toxicity test, fish was exposed to different concentrations (1/2LC50, 1/4LC50, 1/16LC50, 1/256LC50, surface water standard concentration) and killed at 3, 7, 10 and 14 day after exposure.
