The upper Gila River basin is one of the few unimpounded drainage basins west of the Continental Divide, and as such is a stronghold for endemic fishes in the region. Nevertheless, multiple nonindigenous fishes potentially threaten the persistence of native fishes, and little is known of the trophic ecology of either native or nonnative fishes in this system. Gut contents and stable isotopes (C...

A comparative study on the fatty acids contents of three Malaysian marine fishes Tenualosa toli (Terubok), Rastrelliger kanagurta (Kembong), Stolephorus baganensis (Bilis) and three freshwater fishes Channa striatus (Haruan), Pangasius hypothalamus (Patin), Clarias macrocephalus (Keli) were carried out. Marine fishes showed more unsaturated fatty acids with 3, 4, 5 and 6 double bonds than in fr...

Sea bass is a fish widely produced, consumed and appreciated in Italy. Its intensive rearing system provides the consumption of valuable to wider population. Thanks use an appropriate feed, it possible obtain reared sea which are richer total lipid with majority presence polyunsaturated fatty acids, such as n-3 n-6 series. In this study, 75 specimens European coming from three different origins...

A total of one hundred and twenty Clarias gariepinus comprising 30 dead and 30 live fishes were examined for protozoan parasites infestation, sixty each from the wild and a pond (cultured environment) over a period of six months. Ichthyophthirius multifiliis was the most common protozoan parasites found in C. gariepinus from the wild (River Benue) and cultured (pond) environments. These protozo...

Non-native fishes can cause ecological impacts as invasive species, but identifying which non-native species have harmful is critical to prioritizing management and policy responses. Here, we characterized the state of knowledge on a possibly overlooked group in United States: non-game native transplant (NGNT) fishes. We propose that NGNT may be understudied relative game fish exotic introduced...

Chemical defenses against consumers have been hypothesized to be common among marine macro-holoplankton, but few studies have assessed macro-holoplankton susceptibility to predators or the traits affecting palatability. We used generalist fishes to determine the palatability of fresh tissues, freeze-dried homogenates, and chemical extracts from 19 species of macro-holoplankton. Fishes rejected ...

Triplophysa fishes are the primary component of the fish fauna on the Tibetan Plateau and are well adapted to the high-altitude environment. Despite the importance of Triplophysa fishes on the plateau, the genetic mechanisms of the adaptations of these fishes to this high-altitude environment remain poorly understood. In this study, we generated the transcriptome sequences for three Triplophysa...

Introduction Overfishing and climate change have combined to cause fishery stocks decline fish community composition change, further threatening the predation nutritional health of marine mammals. Methods In this study, we collected potential prey fishes catched by fishermen in six habitats Indo-Pacific humpback dolphins analyzed their proximate (moisture, water, fat protein), fatty acid amino ...

Abstract Marine vegetated habitats such as seagrass, mangroves, and macroalgae are common along tropical coastlines globally provide for a diversity of fishes, including juvenile fish species found on coral reefs. Understanding the use these by different life stages is fundamental to spatial planning, fisheries management, conservation. While previous studies have focused habitat potential macr...
