Two new species of anthiine fishes are described from the Marquesas Islands, French Polynesia. Plectranthias flammeus was found at depths from 20-45 m and is characterized by dorsal rays X, 14 or 15, with spines 1-6 bearing fleshy white tabs at their tips, longest fleshy tab on spine 4; 14 unbranched pectoral rays; lateral line incomplete with 16-17 tubed scales; preopercle with 8-10 small spin...

enzymatic hydrolysis of yellowfin tuna visceral protein with neutrase has been carried out by response surface methodology using factorial design. peptide chain length was estimated as the response surface to the hydrolysis conditions (enzyme activity, reaction temperature, and reaction time). the tuna visceral protein hydrolysate had relatively high protein (74.56%) and low lipid content (1.86...

study was undertaken to establish the optimum dietary indispensable amino acid (IAA) profile for yellow fin seabream broodstock based on the amino acid (AA) profile of broodstock, eggs and larvae of Acanthopagrus latus. Three isonitrogenous (40%) and isolipid (20%), named diets 1, 2 and 3 were formulated with different ratios of total essential amino acids per total non-essential amino acid...

The lateral line system of amphibians and fish comprises a large number of individual mechanosensory organs, the neuromasts, and their sensory neurons. The pattern of neuromasts varies markedly between species, yet the embryonic pattern is highly conserved from the relatively basal zebrafish, Danio rerio, to more derived species. Here we examine in more detail the development of the posterior l...

A new species of serranine fish is described from the Philippine Islands. A single specimen of a new species, Chelidoperca santosi, captured by fishermen working in Palawan waters was discovered in the public fish market in Iloilo City, Panay, Philippines. Two additional specimens of the new species, also from the Philippines, were subsequently discovered in the collections of the Museum Victor...

A new species of torrent catfish, Liobargus hyeongsanensis, is described from rivers and tributaries of the southeastern coast of Korea. The new species can be differentiated from its congeners by the following characteristics: a small size with a maximum standard length (SL) of 90 mm; body and fins entirely brownish-yellow without distinct markings; a relatively short pectoral spine (3.7-6.5 %...

Manta rays and tunas are outstanding representatives of propulsion by MPF (median and/or paired fin) BCF (body caudal fin), respectively, it is an interesting topic to see what kind fluid effects will be generated when they meet during the swimming process. In present study, numerical simulations were performed for individual state manta ray/tuna group ray tuna in a tandem arrangement. conditio...

The unusual yellow-finned morph of European perch Perca fluviatilis found in Lake Constance suffers more severely from macroparasite infections, including the tapeworm Triaenophorus nodulosus and the gill worm Ancyrocephalus percae, than conspecifics elsewhere. Microsatellite analysis of yellow-finned P. fluviatilis and red-finned variant recently discovered in Lake Constance revealed significa...
