Influence of protein concentration on the properties of crayfish protein isolated gels
(Taylor & Francis, 2014-03)
Crayfish protein, present in the wastes from crayfish processing, has been investigated as an ingredient of surimi-like gel products, which may be regarded as a renewable, available, and low-cost raw material. The aim of ...
Determination site of vitellogenin synthesis in freshwater crayfish Cherax quadricarinatus at different maturation stages females
(Escuela de Ciencias del Mar <BR>Pontificia Universidad Católica de Valparaíso, 2005)
Effect of temperature on weigth increase, survival, and thermal preference of juvenile redclaw crayfish Cherax quadrecaninatus
The objective was to determine the effect of temperature on the development of Australian crayfish Cherax quadricarinatus juveniles and its thermal preference under laboratory conditions. The determination of the effect ...
Effect of dietary protein level on spawning and egg quality of redclaw crayfish Cherax quadricarinatus
The effect of dietary protein level on spawning and egg quality was evaluated for female Cherax quadricarinatus. Diets containing four different levels of crude protein were evaluated (22, 27, 32, and 37%). After 100 days, ...
Comparative ultrastructure and carbohydrate composition of gastroliths from astacidae, cambaridae and parastacidae freshwater crayfish (Crustacea, Decapoda)
Crustaceans have to cyclically replace their rigid exoskeleton in order to grow. Most of them harden this skeleton by a calcification process. Some decapods (land crabs, lobsters and crayfish) elaborate calcium storage ...
Effects of glyphosate on growth rate, metabolic rate and energy reserves of early juvenile crayfish, Cherax quadricarinatus M.
Early juveniles of the crayfish Cherax quadricarinatus were exposed for 60 d to 10 and 50 mg/L of pure glyphosate (acid form) in freshwater. Mortality was 33% at the highest concentration, while no differences in molting ...
Substrate selection and effect of different substrates on survival and growth of juveniles of the freshwater crayfish Cherax quadricarinatus (von Martens 1868) (Decapoda, Parastacidae)
Survival and growth of juveniles of the Australian freshwater crayfish Cherax quadricarinatus were evaluated in aquaria with four different substrates covering their bottom. The four substrates were plastic mesh, small ...
Effects of atrazine on growth and sex differentiation, in juveniles of the freshwater crayfish Cherax quadricarinatus
(Academic Press Inc Elsevier Science, 2016-09)
The effect of the herbicide atrazine was assayed in early juveniles of the redclaw crayfish Cherax quadricarinatus. Four cohorts of juveniles (a total of 280 animals) were exposed for 4 wk to each one of three atrazine ...
