Pond 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 ...

Loss of much-needed fresh to brackish water reserves and decreased fish catches have serious ramifications. Herein, maps of temporal and regional sediment distributions in Manzala incorporate petrological and statistical analyses of 200 surficial and short core sam...
متن کاملEpigenetics—Potential for Programming Fish for Aquaculture?
Epigenetic marks affecting the expression of genes are triggered by environmental stimuli, can persist throughout life or across multiple generations and can affect an individuals phenotype. In recent years there has been a revival of interest about the possible role of epigenetics in affecting complex or quantitative traits. This growing interest is partly driven by the increasing affordabilit...
متن کاملpotential of aspikutum (a hybrid of leuciscus aspius ♀ × rutilus frisii ♂) for aquaculture: comparison of growth performance in earthen ponds and tanks
production of new hybrids is important for growing aquaculture and protecting wild stocks of fish species. a hybrid between female asp × male kutum ( leuciscus aspius ♀ × rutilus frisii ♂) was produced and its growth performance was monitored in two rearing systems for 55 days. the fish held in earthen ponds exhibited higher performance compared to those held in concrete tanks. the results also...
