Problem statement: Heavy metals constitute one of the most hazardous substances that could be accumulated in biota. Fish populations exploited by man often live in coastal area environments that contain high levels of heavy metals, coming from human activities such as industrial and agricultural wastes. A problem to deal when using fishes as biomonitors of heavy metals is the relationship exist...

Abstract Caranx ignobilis , is one of the iconic culture species in Ambon inner bay recently, unfortunately feeding remains problematic, yet profound importance. This study aimed to examine effect and unfed period cycles on growth trajectories well being during treatment. In totall, 259 fish ranging size 17.05cm-20.47cm SL weight between 142.00 gr - 221.25 were subjected receive three different...

The Laguna Ojo de Liebre (Scammon’s lagoon) is the iconic sanctuary of Pacific gray whale and belongs to El Vizcaino Biosphere Reserve in Baja California, México. From June 2015 August 2016, six seasonal visits were conducted on ichthyofauna seven sites lagoon. By diving, trapping, hook & line, gillnet commercial fishing, a total number 39 fish species was identified belonging 25 families. ...

Abstract A six-treatment study in a 3 × 2 factorial design was conducted to investigate whether dietary supplementation of shrimp hydrolysate (SH) improves the efficacy meat and bone meal (MBM) replacing fishmeal protein juvenile giant trevally Caranx ignobilis . fishmeal-based diet (MBM0) used as control; two low diets were prepared by 25% (MBM25) 50% (MBM50) with MBM; another three treatments...

Currently, spatial and temporal changes in nutrients availability, marine planktonic, and fish communities are best described on a shorter than inter-annual (seasonal) scale, primarily because the simultaneous year-to-year variations in physical, chemical, and biological parameters are very complex. The limited availability of time series datasets furnishing simultaneous evaluations of temperat...

Members of the family Carangidae are top-level predators and highly prized food and sport fishes. Although ecologically and economically important, little is known about the biology of numerous species in the family. This is particularly true of the jacks Caranx ignobilis and C. melampygus, which have experienced recent population reductions around the high Hawaiian Islands due to overfishing. ...

The concentration of Fe, Co, Ni, Cu, Zn, Cd, and Pb in the muscle tissue of marine fishes like Lates calcarifer, Nemipterus japonicus, Caranx melampygus, Rastrelliger kanagurta, and Cyanoglossus macrostomus was estimated from samples collected in the continental shelf waters off Kochi and Mangalore on southwest coast of India. Species-specific and spatially heterogeneous patterns of tissue meta...
