Investigation Of Condition Effects On Batch Fecundity Of The Common Snook, Centropomus Undecimalis, In Tampa Bay, Florida, Catherine Michelle Bruger Hayslip

Graduate Theses and Dissertations

Common snook, Centropomus undecimalis, is a popular game fish species that occurs throughout central and southern Florida, yet many questions remain unanswered regarding their reproductive strategies, including estimates of fecundity with relation to size, age, and condition of the female. These relationships are critical to improving stock assessments and fundamental to estimating spawning potential ratio, the measure by which snook are managed. Spawning snook were collected from a known spawning site, Rattlesnake Key, Tampa Bay, Florida, during three consecutive spawning seasons (2009-2011) and batch fecundity for snook was reported for the first time. Of the 43 females suitable for fecundity ...


Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar Jan 2011

Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar

Graduate Theses and Dissertations

In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C). The eggs were incubated at 28 °C until hatching, which occurred at about 17 hours post-fertilization. After hatching, temperatures were adjusted to the respective treatment levels. Measurements were collected from 25 individual larvae across rearing temperatures at the following pre-determined time intervals: at hatching, 24 hours post hatch (hph), 48 hph, and 72 hph. Morphometric measurements were obtained from photomicrographs, including yolk sac length and height, oil ...
