We used the social-ecological systems framework developed by Elinor Ostrom to explore relationships between gender and collective action. Questionnaires were used to determine (1) motivations to join an association, (2) socio-demographic information, (3) perceptions on key collective action dimensions around leadership and norms within the association, and (4) perceived social performance. Surveys targeted artisanal fisher associations in Chile with varying gender compositions: exclusively male members, exclusively female members, mixed-gender led by a man, and mixed-gender led by a woman. Our results show that women and men have distinct motivations to join an association. Women are primarily motivated by a sense of belonging, while men are mainly motivated by the possibility of an increase in income. Furthermore, associations comprised of women displayed higher valuations on leadership, entrepreneurship, and participation in activities. This likely led to the significantly higher performance of associations that incorporated women (either women-only or mixed gender) in efficiency (30.1%–40.3% higher) and cooperation (13.8%–30.8% higher). Our results extend the social-ecological systems framework towards understanding the role of gender in collective action for fisheries management and specifically contribute to build knowledge and implement novel policy which considers gender in artisanal fisheries in Chile.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70883739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic literature search yielded 804 scientific publications on artificial reefs. A database of their characteristics was constructed and used to investigate geographical and historical trends. A total of 1074 unique artificial reefs from 71 countries were identified, with 89% located in the northern hemisphere, but equally distributed between eastern and western. Reefs were assigned to one of three categories: (A) unintentional deployment, (B) intentional deployment but unintentional reef, and (C) intentional artificial reef. Category A reefs consisted predominantly of accidental shipwrecks. Category B reefs were primarily coastal defense structures in shallow waters and active oil and gas infrastructures at greater depths. The number of Category C reefs increased after 1965, with most in depths of 10–30 m. Most were constructed from concrete or steel, followed by rock and rubber. Usage of concrete as a material steadily increased, while those of steel and rubber decreased, coinciding with the transition from objects (materials) of opportunity to purpose-built reefs. Most reefs were deployed to enhance faunal communities or fisheries, particularly recreational fishing in North America and Australia. Monitoring was most often performed using underwater visual census but transitioned to more technologically advanced methods, particularly in more affluent countries over recent decades. We present a standardized protocol for describing artificial reefs and urge authors to include all relevant data in their publications to allow future comparisons to enhance our understanding and evaluation of these structures.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70882809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study documented the reproductive patterns of 54 coral species in 23 genera and 8 families (41 hermaphroditic spawners, 10 gonochoric spawners, 2 hermaphroditic brooders, and 1 gonochoric brooder) in northern Taiwan by field observations and histological analysis, which indicated that they predominantly spawned in August while fewer spawned in July, September, and October. Based on the field observations, 50 species in 21 genera and 7 families spawned between 20:00 and 22:00 hrs for 5–8 consecutive nights after the full moon in July and August from 2013 to 2016. The spawning patterns varied profoundly in species and colony number from 2014 to 2016: 19 species (42 colonies) in 2014, 6 species (20 colonies) in 2015, and 33 species (120 colonies) in 2016. Most merulinid and lobophyllid corals were observed to spawn consistently over the three years, particularly Favites pentagona, and corals splitly spawned within the colony. Five coral species spawned bimonthly. Three brooding corals (Pocillopora damicornis, Stylophora pistillata, and Porites lichen) also sexually reproduced between summer and early fall. Through this study, we obtained a better understanding of spatial and temporal patterns of the sexual reproduction of corals in nonreefal coral communities. Furthermore, this research may have broader biogeological implications for the northwestern Pacific Ocean region.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70882959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technologies most commonly used include hatchery rearing and release of aquatic animals and provision of artificial structures such as artificial reefs. Both are associated with distinct fields of knowledge and communities of practice. Recent calls to expand and broaden the role of aquaculture and habitat enhancements in marine conservation and an increasingly integrated view of living marine resource management have led to an aspirational broadening of concepts in this area. The 10th William R and Lenore Mote Symposium and 6th International Symposium on Stock Enhancement and Sea Ranching aimed to advance and integrate knowledge across enhancement technologies and practices. Substantial progress was noted in multiple technical areas such as understanding the potential and limitations for rearing organisms fit for release into the wild, and the design of artificial reefs to enhance local fish abundance. Crucial higher-level goals such as effectively enhancing or restoring fish abundance and fisheries at the stock level continue to receive insufficient attention across the enhancement sciences. Integration of enhancement strategies provides opportunities and challenges including a need to recognize, cross-discover, and engage other distinct areas of knowledge and communities of practice. A quick reference guide is provided to facilitate this process.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70883787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combining the two by releasing hatchery reared fish onto artificial reefs is used in sea-ranching operations but is an approach rarely adopted for recreational fisheries. Yellowtail kingfish (Seriola lalandi) form a valuable recreational fishery in Australia and in 2018 a pilot stocking program was initiated to enhance this fishery. Fish were released onto estuarine artificial reefs in Botany Bay to evaluate if estuarine artificial reefs are suitable release habitat for juvenile yellowtail kingfish and to monitor their dispersal patterns using acoustic telemetry and a tag-recapture program. Both approaches showed similar patterns, indicating juvenile yellowtail kingfish rapidly dispersed from the release location and can travel at least 60 km during their first weeks in the wild. Twenty percent of the acoustically tagged fish entered nearby estuaries to the north and south and tagged fish were also recaptured in these estuaries, indicating that the estuaries provide habitat for juveniles. There was little interaction between stocked fish and two large coastal artificial reefs positioned near Botany Bay. Stocked yellowtail kingfish will likely disperse rapidly from release locations which is consistent with their pelagic life history. While this may present challenges to fisheries managers, increasing release numbers to maintain stocking densities over a broader area may provide a solution. Future releases of fish on coastal natural and artificial reefs are an important next step in refining stocking practices for this species and will help further identify key juvenile habitats.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70883390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Misidentification of species with similar morphology is a problem that hampers understanding of cephalopod composition and distribution. In this study, we used morphological and molecular approaches to carry out a comprehensive identification of Octopoda PL that inhabit two main areas (Tamaulipas and Yucatán) in the southern Gulf of Mexico (GoM). A total of 189 PL were identified using morphological criteria. Of these, 52 PL were analyzed molecularly by sequencing the mitochondrial cytochrome c oxidase subunit I (COI) gene. We identified four species and five morphotypes. The molecular tools corroborated three out of four species, while the molecular sequences of three out of four morphotypes indicated that they belong to three different species. All the genetic sequences had high similarities (99.3%–100%) with previous records. One species and one morphotype could not be sequenced because of unsatisfactory fixation; one morphotype remained as such after the molecular analysis. An identification tree was constructed for the species identified with the molecular approach. The species found off the Yucatán platform were Octopus vulgaris Type I, Octopus americanus, Macrotritopus defilippi, Amphioctopus burryi, A. cf. burryi, Octopus sp., and Callistoctopus furvu s. The species identified off the Tamaulipas coast were Octopus insularis and M. defilippi. Paralarvae of O. vulgaris Type I and M. defilippi were the most abundant during 2016–2017.
