Size-at-age vs size-at-stage Environmental control of blue crab growth rates
Meeting Abstract 70.5 Monday, Jan. 6 09:00 Size-at-age vs. size-at-stage: Environmental control of blue crab growth rates DARNELL, M.Z.; Nicholls State University, Thibodaux, LA zachary.darnell@nicholls.edu Blue crab (Callinectes sapidus) size-at-maturity has decreased throughout much of their range where there are commercial fisheries. It has been hypothesized that this may be due to either genetic or environmental factors. […]
