We observed three malformations under the influence of seawater acidification previously undescribed in lobster larvae: a flared carapace, twisted tail, and cross claw. Larvae reared under seawater acidification exhibit significantly lower survivorship (by ⁓14%) and the occurrence of a malformation decreases survivorship (12.7%). Larvae with four types of malformations did not progress through development to reach post-larval stages. Namely, these malformations were a flared carapace, curled carapace, twisted tail, and cross claw.

Considering that the avoidance of PaV1-infected lobsters by early-benthic juveniles is well documented and the previously reported costs of close proximity to PaV1-infected early-benthic juveniles (increased mortality risk), pueruli of P. argus should avoid infected conspecifics during settlement. We experimentally tested if pueruli show aversion to PaV1-infected conspecifics. We also re-tested the previously reported effect of red algae (Laurencia spp.) and healthy conspecifics on pueruli settlement decisions. Considering the known benefits of inhabiting red algae and costs of close proximity to conspecific juveniles, pueruli were predicted to be attracted to metabolites produced by red algae and repulsed by metabolites produced by conspecifics. We also predicted that attraction to red algae would decrease or cease if this cue was presented together with cues produced by PaV1-infected conspecifics. Our experiments indicate that pueruli do not avoid metabolites produced by benthic juveniles and are not attracted to metabolites produced by red algae. Importantly, pueruli are attracted to a combination of metabolites produced by red algae and conspecific juveniles but this attraction ceases if conspecifics are PaV1-infected. Our results indicate that PaV1 disrupts habitat selection by settling pueruli and suggest that assumptions about cost and benefits experienced by settling pueruli need to be revisited. Research to improve the understanding of the relationship between recruitment, disease avoidance, and fishery stock in this heavily exploited spiny lobster is needed.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":"124 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135540538","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}

Previous work has shown skip-molting incidence to occasionally be very high in males, both in NL and some other major snow-crab stocks. This warrants research to better understand impacts of skip-molting on snow-crab age and growth dynamics, which are central to population assessment and resource management. We simulated the impact of skip-molting on growth dynamics of snow crabs from three regions around NL by coupling a nineteen year time series of molt-type probabilities derived from field trawl surveys to historical data on age-at-instar based on cohort analysis of wild populations that do not consider skip-molting in making age estimations. Trawl surveys and simulations showed that skip-molting is a prominent feature in NL snow crabs, with up to four skip-molts being a reasonable maximum possible estimate for males in portions of the NL snow-crab stock. A complementary analysis examining the ability to age snow crabs using gastric mill band counts showed overall strong agreement with published growth trajectories that were modified to include skip-molting as well as reasonable average age approximations for most crabs, but unexpectedly high variability in age estimates for individuals of a same instar stage and unexpectedly low age estimates for younger crabs. Our study leads to a refinement of age at legal size for NL snow crab from the current nine-year estimate to a range of 9–13 years. Although this range is deemed to capture virtually every crab reaching legal size in NL snow-crab populations, ages higher than 11 years to fishery recruitment (2 skip-molts) are relatively infrequent.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":"53 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135775857","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}

We need to clarify the reproductive biology in the invaded habitats as basic information to effectively control the introduced populations, but the reproductive biology of P. clarkii in Japan (especially in western Japan) has not been well studied. We conducted monthly samplings of P. clarkii from November 2015 to November 2016 in a pond (which does not freeze, even in winter) in Okayama, western Japan, both by using shrimp cage traps and by hand nets to examine aspects of the reproduction, including a form alternation (i.e., Form I and II). We also reared spawning females in the laboratory and calculated the accumulated water temperature during the period to Stage-3 juveniles after spawning. The total number of individuals caught throughout the study period was 6,319 (2,601 males and 2,777 females, with eight of unknown sex and 933 juveniles). The males were all Form I with a breeding status from September to November 2016. We first found ovigerous females in July 2016 and females carrying hatchlings in October 2016, even in January 2016. The form alternation in males was confirmed not only in the cheliped length, but in the hook length. In laboratory observations, approximately 52 days with approximately 1,222 °C degree-days of the accumulated water temperature were necessary to Stage-3 juveniles after spawning. Our results indicate that P. clarkii can reproduce within approximately five months of hatching.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":"48 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135976844","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}

This fossil, comprising only the cephalothorax, first pereiopod, and another cheliped, seems closely allied to AustropotamobiusSkorikov, 1907, but also bears an epistome and postorbital carina reminiscent of AstacusFabricius, 1775. For these reasons, it is tentatively assigned to Austropotamobius. It differs from all other Austropotamobius species by the shapes of its epistome cephalic lobe, and postorbital carina, and resemble Austropotamobius torrentium (von Paula Schrank, 1803) most due to its ornamentation. It is therefore described as a new species, Austropotamobius plenicarisp. nov. The new species is associated with brackish water ostracods, most likely reworked from slightly older sediments, suggesting a late Miocene (Messinian) age. The origin of this species and its age show it lived long after the split between Astacus and Austropotamobius, and also probably after the split between the two Austropotamobius species (Au. pallipes and Au. torrentium), and may have been contemporary to, and lived in the area of the diversification of Au. torrentium haplotypes.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":"70 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136318187","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}
