Anatomical brain location was determined for each species using dissection, external photographs and radiographs (see www.ikijime.com website and Ikijime Tool phone apps). Eight dispatch methods were qualitatively evaluated for their effectiveness on sharks of various sizes. Electrical stunning equipment could not be used because it failed to meet Australian electrical safety standards. Field trials of 206 dispatch events found that penetrating captive bolt tools were most effective on medium-sized (120–210 cm) and large sharks (210–360 cm long), with mean total dispatch scores (MTDS) that ranged from 4.6 to 4.84 out of 5 and instantaneous death rate (IDR) that ranged from 88.57% to 95.45% (n = 79), while ikijime was most effective on small sharks (< 120 cm long), with an MTDS of 4.69 and IDR of 93.75% (n = 16). In contrast, percussive stunning (MTDS = 3.95, IDR = 80.95%, n = 42), shooting with a 12-gauge shotgun (MTDS = 2.92, IDR = 36.54%, n = 52) and spinal section (MTDS = 3, IDR = 0%, n = 2) were less effective, as shown by their lower IDR and MTDS scores. These preliminary findings may be useful for directing further research into best-practice dispatch methods for sharks in the NT, Australia, and elsewhere globally.\u0000 </div>","PeriodicalId":50444,"journal":{"name":"Fisheries Management and Ecology","volume":"32 4","pages":"134-146"},"PeriodicalIF":2.0,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Management decisions for rocky-reef gastropod fisheries should consider long-term species mobility, yet this is often poorly understood. Therefore, mark-recapture was used to evaluate annual displacement and upshore-to-downshore movement of T. militaris in Eastern Australia. Tags were glued onto 676 snails, their positions georeferenced and recapture surveys were conducted after 6 and 12 months. Overall, 25% of tagged snails were recaptured. Snails moved an average of 20–21 m year−1 at subtropical sites and 34–44 m year−1 at temperate sites. Movement was non-directional, limited in upshore-to-downshore mixing and unrelated to animal size. T. militaris is neither sedentary nor site-attached, and small and large snails move similarly. Our findings suggest a limited capacity for adults to repopulate other tidal zones, thus recreational harvesting could impact intertidal snails.","PeriodicalId":50444,"journal":{"name":"Fisheries Management and Ecology","volume":"32 5","pages":"189-202"},"PeriodicalIF":2.0,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/fme.12794","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145037877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we assessed the stock status, economic significance, and market status of blackspotted croaker in the Bay of Bengal, Bangladesh. We estimated life history parameters and sustainability indicators to determine if the stock was being sustainably managed. Size of blackspotted croaker was significantly differ temporally. Blackspotted croaker increased in weight allometrically in relation to length. Length-age life history parameters were L∞ = 161.16 cm, k = 0.39 year−1. Natural mortality M was 0.39 year−1 and fishing mortality F was 0.35 year−1. Catch composition and sustainably indicators revealed that the stock was prone to recruitment and growth overfishing. Medium to large sized blackspotted croaker (> 85 cm) fetched the highest price in commercial markets for the swim bladders that was worth many times more than the value of fillets. The highest demand of swim bladders in export commerce termed this species as marine gold to the fishers. Therefore, fishers were increasingly motivated to target the species. Ununiformed landing of blackspotted croaker, for domestic and international trade of swim bladder of blackspotted croaker, and poorly documented trading supply chains make this fishing industry luck-driven.

We quantified catches of sharks and rays in artisanal fisheries at the Parc National du Banc d'Arguin (Banc d'Arguin), Mauritania (West Africa) during 1998–2020, a period when fishing effort increased around 2006, catches increased, but catch-per-unit-effort declined substantially.
