Otolith Shape Analysis and its Utilily for Identification of Two Smelt Species, Hypomesus japonicus and H. nipponensis (Osteichthyes, Osmeridae) from the Northwestern Sea of Japan with Inferences in Stock Discrimination of H. japonicus
Russian Journal of Marine Biology - Tập 46 - Trang 431-440 - 2021
Q. T. Vu, Yu. Ph. Kartavtsev
In this study, otolith shape analysis has been used to perform identification of two smelt species specimens (genus Hypomesus), H. japonicus and H. nipponensis, as well as differentiation of local gatherings in the first species, in the north-western Sea of Japan (SJ). Based on the otolith shape and using several multidimension statistical approaches obvious differences were defined for both inter...... hiện toàn bộ

A Laboratory Study of the Effect of Temperature on the Embryonic Diapause of the Hermit Crab Pagurus proximus Komai, 2000 (Decapoda: Paguridae) from Peter the Great Bay, Sea of Japan
Russian Journal of Marine Biology - Tập 48 - Trang 231-237 - 2022
E. S. Kornienko
Under laboratory conditions, the effect of temperature on the reversible arrest in embryo development, which occurs as a result of winter spawning, was studied in the hermit crab Pagurus proximus, Komai, 2000 from Amurskiy Bay (Peter the Great Bay, Sea of Japan). In clutches of females that spawned under natural conditions at a water temperature of 5°C and below, an increase in water temperature t...... hiện toàn bộ

The Pattern of Glycogen Recovery in Muscles and Liver of Fish with Different Swimming Capabilities after being Caught in a Bottom Trawl
Russian Journal of Marine Biology - Tập 46 - Trang 270-276 - 2020
E. N. Silkina, Yu. A. Silkin, M. Yu. Silkin
The dynamics of glycogen recovery in the muscles and liver of the European flounder Plathichthys flesus (Linnaeus, 1758) and the European sprat Sprattus sprattus (Linnaeus, 1758) after exposure to trawl fishing has been studied. As the results show, the stress-inducing effect of fishing does not alter the glycogen content of the organs in the flounder, which leads a sedentary life, whereas a sharp...... hiện toàn bộ
New records of the sea anemone Ptychodactis patula Appellöf, 1893 (Anthozoa: Actiniaria) in the northern and far eastern Seas of Russia
Russian Journal of Marine Biology - Tập 33 - Trang 54-57 - 2007
S. D. Grebel’nyi
Twenty-two samples of a rare sea anemone Ptychodactis patula having an unusual structure were found in the collection of the Zoological Institute (Russian Academy of Sciences, St. Petersburg). This species was previously referred to the small order Ptychodactiaria, which included only three species. P. apatula was known only from the coasts of Norway (the type locality), Iceland, and the Bering St...... hiện toàn bộ
The composition and structural characteristics of polysaccharides of the brown alga Eisenia bicyclis
Russian Journal of Marine Biology - Tập 39 - Trang 208-213 - 2013
R. V. Men’shova, S. P. Ermakova, B. H. Um, T. N. Zvyagintseva
The present study examines the polysaccharide composition of the brown alga Eisenia bicyclis. The major polysaccharide of E. bicyclis is shown to be sodium alginate (15.8% of the dry defatted alga weight). The yields of laminaran and fucoidan were 1.4% and 1.3% of the dry defatted alga weight, respectively. The alga contains laminaran (1,3;1,6-β-D-glucan) that has a unique structure, a high conten...... hiện toàn bộ
Assessment of the State of the Populations of Two Fish Species Siganus fuscescens (Houttuyn, 1782) and Gerres oblongus (Cuvier, 1830) (Actinopterygii: Perciformes) in the Sublittoral Zone of Malapascua Island (Philippines)
Russian Journal of Marine Biology - Tập 48 - Trang 474-477 - 2022
A. G. Selyukov, O. N. Zhigileva, A. I. Borichevskaya, S. S. Shadrina
The state of organs and genetic polymorphism were examined in the mottled spinefoot Siganus fuscescens and the slender silver-biddy Gerres oblongus. The study revealed massive pathological changes in the gill epithelium and liver of the fish, as well as a low level of genetic polymorphism. This indicates unfavorable environmental conditions in the sublittoral zone of Malapascua Island, threatening...... hiện toàn bộ
On the Species Structure of a Competitive Marine Community
Russian Journal of Marine Biology - Tập 44 - Trang 159-163 - 2018
V. V. Sukhanov
Some examples of marine animal and plant communities with a structure determined by competitive inter-species relationships are discussed. It has been shown that the ranked species structure of these communities obeys a geometric progression, whose coefficient does not differ significantly from the constant exp(–1) = 0.368. A relationship between a certain parameter of this progression and the spe...... hiện toàn bộ
On a Poorly Known Rookery of Green Turtles (Chelonia mydas) Nesting at the Chabahar Beach, Northeastern Gulf of Oman
Russian Journal of Marine Biology - Tập 44 Số 3 - Trang 254-261 - 2018

There is a poorly known rookery of green turtles (Chelonia mydas) nesting in sandy beaches of Chabahar town, northeastern Gulf of Oman, Iran.This study has been carried out to evaluate nesting activity of this small rookery in 2014 nesting season (June to October). In this study, total clutches were collected and transferred to an artificial hatchery. The peak of nesting occurred from the third pa...... hiện toàn bộ
