“…The equation proposed by Ruíz‐Velazco et al . () (Eqn ) is a simplification of the growth curve developed by Hernandez‐Llamas and Ratkowsky (), which has proved useful to model growth of fish, crustaceans and molluscs. The exponential equation (Eqn ) that calculates surviving population is the simplest assumption that can be made when there is only an estimate of final survival.…”

“…The equation proposed by Ruíz‐Velazco et al . () was used to calculate mean individual weight:wt=wnormali+false(wfwifalse)[false(1ktfalse)/false(1khfalse)]3,where w t is mean individual weight predicted after t time units (e.g. 45, if w t is predicted after 45 days of cultivation), w i is the initial weight, w f is the final weight, k is a growth coefficient, and h is the number of time units at harvest time.…”

“…Growth and survival equations were used to predict w t and n t in the stock model, and their parameters were made dependent on water quality and management variables, using 86 cases (ponds) and multiple linear equations (Ruiz‐Velazco et al . ,b). The mean values of water quality variables recorded throughout the cultivation periods were used for analysis.…”

“…In those studies, we developed and validated deterministic stock models for analysis and showed the importance of high levels of dissolved oxygen and an early start of aeration for mitigating the negative impact of the disease (Ruiz-Velazco et al 2010a). We also showed that using small ponds, an early start of aeration and high stocking densities is the most convenient strategy for maximizing shrimp yields (Ruiz-Velazco et al 2010b). Recently, we incorporated stochastic elements into the stock models to study the variability of shrimp yields caused by differences in water quality parameters among ponds, and showed that using small ponds, early start of aeration, high stocking densities and extended cultivation periods maximized yields and diminished variability ).…”
