It was shown that the level of energy metabolism of A. kagoshimensis, while being in the zone of upwelling formation, decreased, on average, by 5% per degree of temperature decrease. During the upwelling relaxation phase (14 → 26°C), the restoration of the respiration intensity parameters of the clam was slower than expected, with a temperature coefficient of Q10 = 1.31. The acidification of the seawater by 1.0 (up to рН 7.2), combined with a temperature decrease (26 → 20°C), aggravated the negative effect by 25–45%. It has been found that the clam A. kagoshimensis reduces energy expenditure by approximately 60% under upwelling conditions (cold stress and acidification). The consequences of the negative effect of a sharp temperature variation lead to a delay in the metabolism recovery to normal values.","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Basic methods for selecting diets for marine mammals have been described in the literature, yet methods developed for certain marine mammal species kept under specific conditions are quite rare. The diets of three male and two female spotted seals, Phoca largha Pallas, 1811, kept in sea pens at the Primorsky Aquarium, Branch of the National Scientific Center of Marine Biology, Far Eastern Branch, Russian Academy of Sciences (Vladivostok, Russia), are discussed in the article. The diets were formulated based on the natural biological processes of this species in the wild. Information on them has been obtained from our own observations and from literature sources. Based on individual needs, adjustments have been made to the diets of the spotted seals, including pregnant and lactating females. The main food items of the spotted seals were Pacific herring, Clupea pallasii, Atka mackerel, Pleurogrammus monopterygius, commander squid, Berryteuthis magister, pink salmon, Oncorhynchus gorbuscha, chum salmon, Oncorhynchus keta, char, Salvelinus sp., capelin, Mallotus villosus, and shrimp, Pandalus sp. It has been found that the physiological status of the animals (molting, reproductive status, sex, and age) directly influences the qualitative and quantitative parameters of food intake. The diet and body weight of the spotted seals were significantly influenced by seasonal changes (water and air temperature and natural biological rhythms). These data can be used for selection of optimal feeding of P. largha.","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new species Oncorhynchus gorbuschka sp. nova Glubokovsky et Zhivotovsky (rosy salmon) is described in detail. The most striking ecological difference between this species and pink salmon Oncorhynchus gorbuscha sensu stricto (Walbaum) is that rosy salmon spawn only in odd years, whereas pink salmon spawn in even years. Thus, these two species form two reproductively isolated broodlines throughout their range. Differences between them can also be found in demographic patterns, morphological traits, protein and DNA markers, and full-genome profiles. Presumably, both of these species are relatively young, having evolutionarily diverged from each other during sympatric allochronic evolution resulting in a single age class in both populations. As a result, all sexually mature individuals of each broodline spawn at exactly 2 years of age and die soon after spawning (although rare exceptions are possible). The separation of these two species of Pacific salmon requires their separate consideration in fundamental and applied studies, fisheries and regulation of fisheries, protection, and artificial reproduction.","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141720882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The daily grazing rates of the copepods increased logarithmically with increasing microalgae concentration. The maximum grazing rates in both species are observed when feeding on I. galbana at a concentration of 170–196 μg C/mL. The maximum daily EPR in females of C. aquaedulcis (129% of the body weight in the carbon equivalent) were obtained when they fed on I. galbana at a concentration of 15.4 μg C/mL or on P. cordatum at 4 µg C/mL. The maximum EPR values in A. salinus females were 34% of their weight in the carbon equivalent when feeding on P. cordatum at a concentration of 26 μg C/mL, and 45% in their carbon equivalent at 8.9 μg C/mL of I. galbana. The further increase in the microalgae concentration leads to a decrease in the EPR values. The efficiency of ingested food utilization for egg production in the carbon equivalent (gross growth efficiency, GGE, %) of C. aquaedulcis was significantly higher than that of A. salinus, regardless of the species and concentration of microalgae.","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141720885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
