On the development of the total allowable catch of Okhotsk herring Clupea pallasii Cuvier et Valenciennes, 1847 in 2001–2016

Andrey M. Panfilov

The dynamics of catch and the structure of the Okhotsk herring fishery in 2001–2016 are considered.

The reasons for the reduction of catches during the spawning period are considered. In the current century, the annual total allowable herring catch is not fully developed. The herring fishery is divided into 3 periods: the wintering (pre-spawning), spawning and feeding. In the spawning and feeding periods, the catch does not correspond to the value of the allocated quotas. About half the size of the shortage is due to the state of the spawning herring fishery. The reasons for the decrease in the catch of spawning herring are analyzed. It is shown that the growth of catches is hindered by the uncertain status of the Okhotsk herring in the inland waters. An analysis is made of the state of the fishery of the spawning herring, and recommendations are given to increase the catches.

Opportunistic cetacean observations in North-Western Pacific and Sea Of Okhotsk in May–June 2017

The observations reported here were conducted aboard the vessel “Professor Khromov” during its trip from Petropavlovsk-Kamchatsky to Commander Islands, Kuril Islands and along the western coast of the Sea of Okhotsk. In 24 days we traveled 7834 km during which we made 212.5 hours of visual observations of the water area. We recorded 65 encounters with 176 cetacean individuals of ten species. Seventy-three percent of observed encounters were off the Eastern Kamchatka and Commander Islands. The Eastern Kamchatka and Commander Islands regions in May–June are important migration and foraging areas for cetaceans, including endangered species such as blue whale, fin whale and humpback whale.

Productivity and biomass dynamics of pacific hering Clupea pallasii of Tauyskaya Bay in the population structure of the species in the Sea of Okhotsk 

R.R. Yusupov, Elena V. Kashchenko

Biomass dynamics and formation of somatic production of the Tauyskaya Bay herring population and the other populations of this species in the Sea of Okhotsk and adjacent waters were studied on the base of author’s own materials and literature data. It was found, that depending on the features of the body weight growth rates and natural decline with ages, there can be differences between herring populations, illustrated by asymmetry of the biomass dynamics parabolic curves, characterizing different biomass growth or reduction rates. In this parameter the Tauyskaya Bay herring population is close to the Gizhiga-Kamchatka’s population, and both represent  large  population  cluster  of  herring  on  the  southeast  of  Kamchatka.  All  these  populations  are characterized by comparatively slow increase of the biomass with ages and late culmination of the biomass. On the contrary, the Okhotsk population of the species, it being close to the Tauysk herring population in geographical sense, is more similar with the population of the De Castries Bay. Both demonstrate similarity with the population cluster of Eastern Sakhalin. On the productivity index (Р/В-factor), the Tauyskaya Bay herring population is minor comparing to the Gizhiga-Kamchatkan or Okhotsk populations, what can be due to historically small area occupied, limited from the east and west by distribution of mentioned large populations.

Assessment of regional origin and distribution of hatchery pink and chum salmon on results of otolith marking in the basin of the Sea of Okhotsk in the fall period of 2016  .

Аlexandra. I. Chistyakova, Оlga О. Kim, Viktor S. I

Otolith structures of juvenile pink and chum salmon from trawl catches of complex surveys provided in October–November of 2016 by R/V “Professor Kaganovsky” were examined. The otolith samples for the analysis were collected from 600 pink salmon individuals and 1150 individuals of chum salmon. Obtained results allow to identify hatchery marked fish in mized catches. In the total there were 15 (2.5%) pink and 50 (4.3%) chum salmon individuals revealed with otolith marks of different salmon hatcheries (SHs) of Russian Far East and Japan. Structure of hatchery juvenile release in the Sea of Okhotsk basin was analyzed. The highest number of juvenile pink and chum salmon was released from the Shs of Sakhalin, and the leader in the release of marked juvenile pink was Sakhalin cluster of the hatcheries, and of chum salmon – the cluster of Japan. It was figured out based on the analysis of the otoliths of juvenile pink salmon from the Sea of Okhotsk, that the percental contribution of fish from different regions into the catches is generally fits structure of the release of marked juvenile pink salmon from the SHs of Russian Far East and Japan. In the ratio between marked Russian and Japan juvenile chum salmon in the Sea of Okhotsk juvenile aggregations the part of Russian hatcheries was first time ever higher than the part of the hatcheries of Japan, what can indirectly evidence in favour of increasing survival of marked fish from Russian SHs and better quality of the marks.

It was figured out during analysis of the distribution of marked juvenile pink salmon in the west part of the Sea of Okhotsk, that the sites of the catches of marked pink in most cases coinsided with the sites of increased density of pink salmon underyearlings. Analysis of distribution of marked juvenile chum salmon in the waters of the sea has revealed that in 2016 there was rather obvious spatial dissociation between feeding juvenile salmon from Russian and Japan SHs.

Питание синего краба Paralithodes platypus в заливе Бабушкина (Охотское море) в июле 2011 г.

Sergey V. Klinushkin

Исследован состав пищи синего краба в районе зал. Бабушкина (Охотское море) в июле 2011 г. Основным представителем фауны бентоса были усоногие раки рода Balanus, которые являлись и главным
пищевым компонентом синего краба. Весовой анализ содержимого желудков синего краба показал,что у самцов и самок структура питания различалась. У самок в пище преобладали ракообразные —
92,1%, вклад остальных компонентов (моллюски, полихеты, водоросли) при этом невелик. У самцов в питании значительно выше роль моллюсков (33,3%) и полихет (10,0%), хотя доля балянусов, как и у
самок, тоже велика (51,2%). Весовые доли водорослей и детрита незначительны. При одинаковой доступности пищи у самок и самцов, интенсивность питания была различной. Самки (как половозрелые,
так и неполовозрелые) питались интенсивно: средний индекс наполнения желудка составил 19,97 и 25,26‱соответственно. У непромысловых самцов интенсивность откорма была значительно ниже — 7,60‱.

Некоторые сведения о поимках личинок тихоокеанской трески Gadus macrocephalus у западного побережья Камчатки в 2015 г.

Darya Ya. Saushkina, Andrey A. Matveev, Vladimir V. Kolomeytsev, Ekaterina V. Batalova

О встречаемости личинок и мальков тихоокеанской трески в восточной части Охотского моря данных в литературе практически не имеется. Известно, что на протяжении некоторого времени после выклева личинки трески остаются в районе нерестилищ (Mishima, 1984). Дальнейшее распределение личинок непосредственно связано с течениями. В работе использованы данные, полученные по результатам ихтиопланктонной съемки, выполненной в июне 2015 г. на западнокамчатском шельфе. Цель данной работы — обобщить имеющиеся сведения о поимках личинок трески у западного побережья Камчатки, дополнить их современными данными, привести данные морфометрического анализа. Личинки трески были пойманы над глубинами от 20 до 86 м при температуре воды у дна от +0,9 до +4,3 ºС, у поверхности — от +3,8 до +8,2 ºС в районе, ограниченном координатами: 51º07׳с. ш. 156º30׳в. д. – 53º28׳с. ш. 155º43׳в. д. В июне 2015 г. направление осредненного по всему исследованному району переноса соответствовало восточному – юго-восточному сектору. Такие условия могли дополнительно способствовать перемещению личинок трески в направлении берега, т. е. с больших на меньшие глубины. Большая часть тела личинки пигментирована рассеянными под кожей коричневыми пигментными клетками. Среднебоковой пигментный ряд начинается сзади вертикали ануса. Крупные меланофоры располагаются  на  голове,  нижней челюсти и в  передней части брюшной области. Полная длина тела (TL) личинок варьировала от 7,77 до 12,65 мм, длина головы до заднего края жаберной крышки (HL) — от 1,39 до 3,19 мм. Глаза довольно крупные и составляют в среднем около 38% длины головы или 8,2% полной длины тела личинки.
