Spawning rhythms of common snook in Florida

Journal of Fish Biology, 1998
Common snook Centropomus undecimaliswere sampled monthly from the Jupiter–Lake Worth area of Florida's Atlantic coast during 1989 and 1991 (1452 fish) and from Tampa Bay on Florida's Gulf of Mexico coast during 1988 and 1989 (2090 fish). Group‐synchronous oocyte development was demonstrated. Ovarian maturation began during March or April on both coasts.

Testicular maturation and regression in the common snook

Journal of Fish Biology, 1998
During the annual reproductive cycle, the lobular testis of Centropomus undecimalis undergoes height, width, and morphological changes which reflect five reproductive classes: regressed; early, mid‐, and late maturation; and regression. Histological criteria, particularly differences between continuous and discontinuous germinal epithelia, are used to ...

Trophic Ecology and Resource Partitioning of Common Snook and Mexican Snook in the Usumacinta River Delta

Transactions of the American Fisheries Society, 2022
AbstractCoexisting species often develop resource‐partitioning mechanisms to reduce their direct competition and optimize energy harvesting. Common Snook Centropomus undecimalis and Mexican Snook C. poeyi are carnivorous fish that coexist in estuaries of the Usumacinta River delta, in the southern Gulf of Mexico, and play an important role for ...

Digestive enzyme activities during early ontogeny in Common snook (Centropomus undecimalis)

Fish Physiology and Biochemistry, 2011
Common snook (Centropomus undecimalis) is one of the most important marine species under commercial exploitation in the Gulf of Mexico; for this reason, interest in developing its culture is a priority. However, larviculture remains as the main bottleneck for massive production.

Energetics of Swimming in Juvenile Common Snook, Centropomus undecimalis

Environmental Biology of Fishes, 2002
Little research has been devoted to the investigation of swimming energetics and performance in lie-in-wait predators. This study evaluated activity metabolism and swimming performance in juvenile snook, Centropomus undecimalis, a lie-in-wait predator, by determining oxygen uptake in a tunnel respirometer.

Maturation of female common snook Centropomus undecimalis: implications for managing protandrous fishes

Journal of Fish Biology, 2020
AbstractThe assumption for hermaphroditic fish species that mature individuals of the terminal sex arise directly from mature individuals of the primary sex has led to the use of sex ratios as a proxy for age at maturity (A50). The timing of transition and deficient energy reserves, however, can result in a delay between transition and spawning.

Embryonic and Early Larval Development in Hatchery-Reared Common Snook

North American Journal of Aquaculture, 2012
Abstract To gain an improved understanding of the early life history of common snook Centropomus undecimalis and refine hatchery production techniques for this species, a combination of digital photography and histological techniques were used to document the embryonic and early larval development of hatchery-reared individuals.

Myxosporean Parasites of Common Snook in Florida

Journal of Aquatic Animal Health, 1993
Abstract Three species of myxosporeans were found in common snook Centropomus undecimalis in Florida. One of the species is described as Myxobolus centropomi n. sp. (trophozoites in gill, pseudobranch, and under scales), and another is described as Ceratomyxa choleospora n. sp. (trophozoites and spores in gallbladder, spores in fecal casts).

Effects of salinity on physiological conditions in juvenile common snook Centropomus undecimalis

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2006
This study describes the effects of different salinities on oxygen consumption, ammonia excretion, osmotic pressure, apparent heat increment, postprandial nitrogen excretion, and oxygen:nitrogen ratio in juvenile common snook Centropomus undecimalis.
