Abstrac t —Although bocaccio (Sebastes paucispinis) was an economically important rockfish species along the west coast of North America, overfishing has reduced the stock to about 7.4% of its former unfished population. In 2003, using a manned research submersible, we conducted fish surveys around eight oil and gas platforms off southern California as part of an assessment of the potential val...

Narrow barred Spanish mackerel and wolf herring is an important commodity that has commercialized intensively to fulfill the needs of market, both domestic export. Research been conducted from June-August 2020 in Malacca Strait Waters. The purpose this study analyze dynamics population parameters such as growth rate, mortality exploitation rates, recruitment patterns narrow (Scomberomorus comme...

We previously identified the cellulase SnEG54 from Japanese purple sea urchin Strongylocentrotus nudus, the molecular mass of which is about 54kDa on SDS-PAGE. It is difficult to express and purify a recombinant cellulase protein using bacteria such as Escherichia coli or yeast. In this study, we generated mammalian expression vectors encoding SnEG54 to transiently express SnEG54 in mammalian c...

This study was undertaken to identify an opsonin in the coelomic fluid of Strongylocentrotus nudus by separating several humoral defense factors using galactose-affinity chromatography. A galactose-binding-protein had no opsonic activity against rabbit and sheep erythrocytes, whereas the galactose-unadsorbed fraction and hemolysin fraction separated by affinity adsorption onto formaldehyde-fixe...

The main objective of this work is to contribute to the taxonomic knowledge of the species of Capitellidae reported for the Eastern Tropical Pacific. This catalogue includes the original name of each species, new names, synonymies, type localities, the museum or institution where the type material is deposited, revision of the material reported for the region by different authors, new examined ...

Previously considered an actinopterygian or an osteichthyan incertae sedis, the Devonian (Givetian-Frasnian) Holopterygius nudus is reinterpreted as a coelacanth. This genus is among the oldest coelacanths known from articulated remains, but its eel-like morphology marks a considerable departure from the conventional coelacanth body plan. A cladistic analysis places Holopterygius as the sister ...
