A study was conducted during 2013-2015 in 13 Tunisian reservoirs. A total of six fish species belonging to three families were collected using multi-mesh gill nets (EN 14575 amended) for the first time. Fish sampling was made in the most important Tunisian reservoirs for analysis of fish...

Freshwater bodies are increasingly affected by reductions in water quantity and quality and by invasions of exotic species. To protect water quantity and maintain the ecological integrity of many water bodies in central Florida, a program of adopting Minimum Flows and Levels (MFLs) has begun for...

The tropical Atlantic fangtooth moray Enchelycore anatina (Lowe, 1838) (Muraenidae) has naturally extended its range into the Mediterranean in the last decades. The record of a third specimen of the fangtooth moray, in the coastal waters of southeast Adriatic Sea, results in listing the species as...

In the current scenario of defaunation and bioinvasion, increasing the knowledge about the composition in marine species and monitoring are an emergency need to control the biodiversity. Nearly 35 years have passed since Türkay (1982) published the decapod crustaceans of the Cape Verde islands. No...

By the late 20th century, a series of events or 'natural experiments', for example the depletion of apex predators, extreme eutrophication and blooms of invasive species, had suggested that the Black Sea could be considered as a large ecosystem 'laboratory'. The events resulted in regime shifts...

Latin America has tripled production by aquaculture up to 78 million tonnes in the past 20 years. However, one of the problems that aquaculture is facing is the presence of helminth parasites and the diseases caused by them in the region. In this review we have collected all the available...

The invasive Portunus segnis, an atlantic species, was recently recorded in Tunisian waters. Since its record in the Gulf of Gabes, no studies have been carried out about the biochemical analysis of this alien species. In this context, our study aims to evaluate the fatty acid profile, lipid...

In spite of growing concerns about the invasion of the sun-coral Tubastraea coccinea along the tropical Southwestern Atlantic, the biological interactions mediating this species' establishment and spread are largely unknown. Here, we identified species associations with T. coccinea by comparing...

Introduction of invasive species is a major threat to freshwater biodiversity. Topmouth gudgeon, pumpkinseed sunfish and black bullhead catfish have been recognised as highly invasive fish species in Croatia. However, their diet in allochthonous habitats are generally still poorly understood, and...

The quantity and distribution of freshwater are fundamental to many ecosystem services, including water supply, flood attenuation, habitat provision, electricity generation, navigation, and recreation. Non-native plants and animals can degrade hydrological functions through their physiology,...
