Culture of the Australian red-claw crayfish Cherax / quadricarinatus in Israel III. Survival in earthen ponds under ambient winter temperatures
The survival of the tropical crayfish Cherax quadricarinatus in earthen ponds under ambient winter temperatures was studied in the temperate zone in the central coastal plain of Israel. Four treatment groups in which sex and size were each tested at two levels were simultaneously run in Ž . four replicates over a period of 118 days 28 November 1996–26 March 1997 . Minimum and maximum water temp...
متن کاملBeneficial acclimation: sex specific thermal acclimation of metabolic capacity in the striped marsh frog (Limnodynastes peronii).
Reproductive success in thermally varying environments will depend on maintaining metabolic capacity of tissues that are important in mating behaviours. Here we test the hypothesis that cold acclimation will occur in those tissues that are important for reproduction, and that acclimation will be sex specific, reflecting behavioural differences between the sexes. We used the frog Limnodynastes p...
متن کاملEffects of stocking densities on growth and survival of Thai Sharpunti (Barbonymus gonionotus) in earthen ponds
The present study was conducted over 4 months during 1 September to 30 December 2005 to observe the effects of stocking density on growth and survival of Thai Sharpunti, Barbodes gonionotus in 3 earthen ponds of size of 2.8 decimal each. The stocking densities of 80, 100 and 120 fish/decimal were treated as T1, T2 and T3, respectively. All the treatments were subjected to the same feeding regim...
متن کاملPond heat and temperature regulation (PHATR): Modeling temperature and energy balances in earthen outdoor aquaculture ponds
A pond heat and temperature regulation (PHATR) model was designed to: (1) predict the temperature for earthen outdoor aquaculture ponds and (2) determine the size of energy transfer mechanisms affecting energy gains or losses for these ponds. The model solves a first order, no-linear differential equation using a 4th order Runge-Kutta numerical method and various input data (weather data, pond ...
متن کاملEffect of Oxygen Management on Culture Performance of Channel Catfish in Earthen Ponds
—Aeration allows for higher feeding rates and increased production of channel catfish Ictalurus punctatus in intensive and semi-intensive aquaculture systems. However, the effect of specific dissolved oxygen (DO) concentrations on various production parameters remains unknown. The purpose of this 2-year study was to determine the effect of daily minimum DO concentration on channel catfish produ...
