Аннотация: 7512 экз. рыб длиной 10,0 - 41,5 см, в возрасте от 1 года до 15 лет обследованы на заражённость личинками нематод Anisakis simplex в российской экономической зоне 26-го подрайона ИКЕС. Для всех рыб определён возраст и принадлежность к весенненерестующим "прибрежным", весенненерестующим "морским" и осенненерестующим группировкам. Личинки обнаружены у рыб, относящихся исключительно к весенненерестующим "прибрежным" сельдям. Среднее значение экстенсивности инвазии - 5,2%, индекса обилия - 1,1 экз., средней интенсивности инвазии - 21,6 экз. Интенсивность инвазии изменялась от 1 до 204 экз./7,512 fish specimens (length 10.0-41.5 cm, age 1.0-15 years) caught in the Russian Economic Zone of ICES sub-area 26 were analysed to estimate infestation with Anisakis simplex larvae. Age of the individuals under analysis was determined; their belonging to the spring-spawning "coastal", spring-spawning "marine" or autumn-spawning groups was found out. The Anisakis simplex larvae were found only in spring-spawning "coastal" herring. The mean values for invasion extensity (5,2%), abundance index (1.1 spm) and average invasion intensity (21.6 spm) are presented. Invasion intensity varied from 1 to 204 specimens.

Аннотация: A feeding strategy for the early stages of development of the red king crab was generated. The material taken for the strategy included the results of experiments to find out the rate of the passage of feed through the gastrointestinal tract, diet preference, and testing of various feeds. The work was done on red king crab larvae and juveniles. Advice for optimal feeds, regime of feeding, and methods of introducing feeds to the larval stages and to juveniles are given.

Аннотация: Changes of stages of redroductive cycle, molting cycle and some other features of biology of the northern shrimp (Pandalus borealis eous) were studied based on data of daily biological analysis, grouped to five days during 10 months (from March to December) of the calendar year. Materials were collected in Pritaujskiy area in northern part Sea of Okhotsk. Reproductive cycle of females lasts for two years: during first year gonads developed up to the spawning and in the second one females carried eggs on pleopods up to hatching of larvae and beginning a new cycle. Changes can be traced by the share of the relevant stages in the total number of individuals in three groups: males, females of first year reproductive cycle and females of second one. The males have two molts for the year and females, according to the spawning cycle have three molts during two years. All molts lasts 2-3 months and diverge in terms. By changes of share of females of first and second year of reproductive cycle hypothesis about vertical migrations was made. The share of females with sternal spines, that take part in process of reproduction first time, is about 45%, which means that females are able take part to three spawning cycles.
