In two series of experiments, ultraviolet light (UV) irradiation doses to inactivate sperm genome and optimal temperature shock to restore diploidy were established. Eggs of white bass were inseminated with sperm from striped bass M. saxatilis diluted (1:30) in saline and irradiated with UV at doses ranging from 50 to 1,200 J/m2. A typical “Hertwig effect” was observed with increasing UV dose. Larvae obtained at doses of 400 J/m2 and greater were abnormally developed (haploid syndrome) and had a haploid chromosome number (n = 24). Heat shocks to cause retention of the second polar body were applied. Heat shocks of 2-min duration at 36°C, 38°C, or 40°C were applied at 2 or 3 min after insemination to white bass eggs inseminated with irradiated (800 J/m2) striped bass sperm.

The five formulated diets were fed to larvae in combination with live brine shrimp Artemia sp., which served as a control. There was no diet effect (P ≤ 0.05) on mean survival, which ranged from 67.4% to 58.3%. Lake sturgeon fed only brine shrimp were significantly greater in mean length (60.4 mm) at 68 d of age than all other treatments, and BioKyowa produced the lowest (44.2 mm) mean length. Mean weight of fish provided brine shrimp (0.74 g) was significantly greater than the weights of those fed the Tunison, Biodiet, or BioKyowa diets.

The objective of this study was to evaluate the effect of phosphorus from a newly constructed public fish hatchery (known as the Oneida Fish Culture Station or OFCS) on Cladophora abundance in nearshore areas of Oneida Lake, New York. Our approach was to monitor total phosphorus (TP) and soluble reactive phosphorus (SRP) above and below the OFCS (on Scriba Creek) and at a reference site (Murray Creek) and to index Cladophora abundance at nearshore areas surrounding both streams from late April to early October 1993–1995. The OFCS has a unique particulate disposal system that involves the settling and subsurface leaching of supernatant to minimize phosphorus discharges. The amount of phosphorus entering Scriba Creek annually from the OFCS was estimated to be less than 38 kg. Although concentrations of TP and SRP tended to be higher downstream of the OFCS, these higher levels w...","PeriodicalId":22850,"journal":{"name":"The Progressive Fish-culturist","volume":"26 1","pages":"263-271"},"PeriodicalIF":0.0,"publicationDate":"1998-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79302353","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}
