Production of Triploid Rainbow Trout for Evaluation in South Dakota Waters
… red blood cells using flow cytometry. Rates of triploidy induction ranged from 0-100%, and all variables (temperature, time after fertilization when heat shock began, and duration of heat shock) significantly (p ≤.01} affected triploid yield. The most successful treatment under the conditions of …

Triploid induction in the South African abalone, Haliotis midae
… was undertaken to determine whether triploidy could be induced and improve the growth rate of the South African abalone, Haliotis midae. From the polar body counts at 17 °C the release times of polar body 1 and 2 were found to be at 12 - 15 min. post insemination (pi.) and 33-36 min. …

Effects of maturation, polyploidy, and nutrition on growth, composition, and gene expression within fatty acid metabolism in rainbow trout
… fillet quality. The aquaculture industry induces triploidy to generate sterile individuals; however, differences in lipid metabolism of female diploid (2N) and triploid (3N) trout may alter fillet quality. In addition, there is concern that genetic selection for increased growth negatively impacts …

Efficacy of Genetic Testing Methodologies for Prenatal Detection of Skeletal Anomalies and Craniosynostosis Syndromes
… syndromes. Three of the confirmed diagnoses were triploidy and Cri du Chat, not true skeletal dysplasia syndromes, whereas the remaining 53 cases were molecularly confirmed skeletal dysplasia syndromes. Genome sequencing would be expected to detect all 59 diagnoses while skeletal dysplasia panels …

Polymorphic social organisation in a eusocial insect : the ultimate and proximate causes
… Importantly, there have been no reports of triploidy in polygynous populations showing that variation in social organisation, along with associated life-history traits and ecological factors, can determine the frequency of matched matings and increase the risk of genetic load. The research …

Production and Flow Cytometric Identification of Triploid Walleyes
… I 00% mortality in all but one treatment. Triploidy was produced by four of the six heat-shock treatments: 29oC-l MAF-25 min (20%), 3IoC-l MAF-25 min (100%), 3loC-3 MAF-25 min (92%), and 3loC-5 MAF-25min (75%). Diploid/tetraploidmosaicism was observed at a rate of 5% with a heat shock of 3 …

A population dynamic model assessing options for managing eastern oysters (Crassostrea virginica) and triploid Suminoe oysters (Crassostrea ariakensis) in Chesapeake Bay
A demographic population simulation model was developed to examine alternative fishery management strategies and their likely effects on the probability of extirpation of local eastern oyster (Crassostrea virginica) populations in the Chesapeake Bay. Management strategies include varying the …
