As a result, most research universities have now invested considerable resources in the construction of large zebrafish facilities. A key element in the design of these facilities is maximizing the efficiency of available space. Here we report on the effects of aquarium chamber volume on the reproduction of zebrafish, with the objective of identifying the minimal volume required for normal egg production. Six adults (two males and four females) were tested in chamber volumes of 500, 400, 300, 200, and 100 mL. Results were compared with those from a control volume of 3.5 L. Eggs were removed from the test chambers after spawning and incubated in petri dishes at 28°C.

In these same systems, the use of brine shrimp Artemia spp. as the first food item for larval fish is also very common. The potential of brine shrimp to inoculate culture water with pathogenic bacteria is well understood, and the increasing availability of ozone makes it reasonable to consider ozone as a potential disinfectant of brine shrimp. In this study, brine shrimp nauplii were exposed to ozone (0.75 g/h) for various periods (10, 15, 20, 25, and 30 min). Survival of nauplii was greater than 90% in all but the 30-min exposure (84.4%), and bacterial reduction was nearly 100% for all exposures. Ozone, because of its demonstrated potential to disinfect brine shrimp without causing significant mortality, is a viable alternative to chemical disinfection of nauplii before feeding to larval fish.","PeriodicalId":22850,"journal":{"name":"The Progressive Fish-culturist","volume":"38 1","pages":"149-151"},"PeriodicalIF":0.0,"publicationDate":"1998-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84357232","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}

Treatment fish were also subjected to a standardized stress challenge (1 h confinement) to evaluate their ability to deal with disturbances subsequent to a handling or tagging procedure. Circulating levels of cortisol and glucose were used as indicators of stress. Each of the treatments elicited very similar responses among treatment groups.
