RNA/DNA ratios in white muscle as estimates of growth in rainbow trout held at different temperatures
TL;DR: Fish reared at warmer temperatures had lower concentrations of RNA for both a given growth rate and a given DNA concentration compared with cold-reared trout, and warm-rearing fish had higher concentrations of DNA and higher protein/DNA ratios than cold- reared trout when fish size was standardized.
Journal ArticleDOI
Growth, Survival, and Body Composition of Cage-Cultured Nile Tilapia Oreochromis niloticus Fed Pelleted and Unpelleted Distillers Grains with Solubles in Polyculture with Freshwater Prawn Macrobrachium rosenbergii
TL;DR: It is suggested that DDGS provides economical growth intilapia when fed as a direct feed and that polyculture of tilapia may improve overall pond efficiency in freshwater prawn production ponds, even at temperate latitudes.
Journal ArticleDOI
Growth and Production of the 1955 to 1972 Cohorts of Perch, Perca fluviatilis L., in Windermere
TL;DR: The von Bertalanffy growth model fitted the data well and values for the model are presented for male and female cohorts of perch from 1955 to 1972, and absolute fecundity per unit length has increased over the period of investigation.
Journal ArticleDOI
Biology of the western pygmy perch, Edelia vittata, and comparisons with two other teleost species endemic to south-western Australia
L. J. Pen,Ian C. Potter +1 more
TL;DR: The peak time, duration and predominant locality of spawning, the time of day when maximum activity occurs and the diet ofEdelia vittata differs from those previously recorded forGalaxias occidentalis andBostockia porosa, likely to minimize any potential competition amongst these three species.
Journal ArticleDOI
Comparison of deterministic growth models fitted to length-at-age data of the piked spurdog (Squalus megalops) in south-eastern Australia
TL;DR: Age and growth estimates of Squalus megalops were derived from the first dorsal fin spine of 452 sharks, ranging from 274 to 622 mm total length, from which a two-phase von Bertalanffy model produced the best fit.
