This species is a freshwater native and is fond of mollusks, intermediate hosts of schistosomes that transmit human diseases in the wild. The larval production of this species occurred in six (06) tanks - two 200 L and four 600 L. The management of brood stock took place in fresh water, with a ratio of one male to four females. Each fertilized female produced thousands of eggs attached to the abdomen until hatching about two weeks later. The larvae resulting from this reproduction were raised to the post-larval stage in brackish water at a salinity of 15 ppt. The larvae must undergo a molt between each stage. We identified 15 morphological stages between stage 1 and the post-larval stage. The duration from stage 1 until onset of the first post-larval stage in the six (06) tanks was on average 54 days after hatching. The success of larvi culture is defined by the rate of metamorphosis of the larvae into post-larvae, which, in our case, varied between 0.17% and 3.08%, depending on the production tanks, with an average of 2.8%. These results show that the production of M. vollenhovenii in hatchery is possible, presenting a possibility for aquaculture production of this species as well as for biological control against schistosomiasis in a tropical area","PeriodicalId":442266,"journal":{"name":"Journal of Marine Biology and Aquaculture","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123174773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its venom can induce small to severe skin lesions and systemic toxicity. Hypertonicity and modulation of pH could prevent more nematocysts from discharging and relieve symptoms.\u0000\u0000Methods: This open-label observational study was performed on Mediterranean beaches by rescuers under the authorization of the Ministère de l’Interieur en France (French Ministry of the Interior). Lesions were evaluated for size, general appearance, erythema, pain, and edema. A hypertonic amphoteric solution, Jellywash® solution (Laboratoire Prevor, Valmondois, France), was used for decontamination regardless the delay.\u0000\u0000Results: 64 victims were exposed to Pelagia noctiluca jellyfish. 78% were > 30 years old, with 27 females and 37 males. 83% of the lesions were small (less than 50 cm2). 78% of the exposed victims were treated within the first 40 minutes. Decontamination had positive results for general appearance in 80% of the victims. Pain decreased in 97% of cases with complete relief in 58% and no effect in 3%. Decontamination was followed by decreased edema in 86% of cases, had a minor effect in 8%, and no effect in 6%.\u0000\u0000Conclusion: Decontamination with a hypertonic amphoteric solution can potentially help ameliorate or prevent development of lesions and symptoms due to contact with Pelagia noctiluca jellyfish.","PeriodicalId":442266,"journal":{"name":"Journal of Marine Biology and Aquaculture","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123411516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
