Growth, Physiological Response, and Gill Health of Spotted Rose Snapper (Lutjanus guttatus) Reared at Different Salinities [PDF]

open access: yesFishes
The physiological and gill health responses of juvenile spotted rose snapper (Lutjanus guttatus) were evaluated at four salinities—8, 16, 24, and 32‰—over a 70-day period.

Induced spawning and larval rearing of spotted rose snapper, Lutjanus guttatus, at the Marine Biology Station, Puntarenas, Costa Rica

open access: yesCiencias Marinas, 2008
Wild spotted rose snapper, Lutjanus guttatus (n = 400, 60–100 g), were captured and grown out in cages during one year (February 2001 to February 2002).

Generation cycle closure of the spotted rose snapper, Lutjanus guttatus, in captivity [PDF]

open access: yesRevista de biología marina y oceanografía, 2012
The spotted rose snapper, Lutjanus guttatus, is culture in several Latin American countries. The present study reports the generation closure with juveniles obtained from wild adults which matured and spawned at a Mazatlan laboratory (Mexico). F1 fish were sexually matured at 2 years of age, and spawning was induced in 2 successive years.

Improved Induced-Spawning Protocol for the Spotted Rose Snapper (Lutjanus guttatus) [PDF]

open access: yesIsraeli Journal of Aquaculture - Bamidgeh, 2009
An improved protocol for hormonal induction of spawning in spotted rose snapper (Lutjanus guttatus) resulted in increased spawning efficiency in newly-caught wild breeders and wild-caught adults maintained in captivity for more than a year. A controlled-release delivery system (implant) based on an ethylene-vinyl acetate copolymer (EVAc) matrix was ...

The use of three anaesthetics for handling spotted rose snapper Lutjanus guttatus (Pisces, Lutjanidae) broodstock [PDF]

open access: yesRevista de biología marina y oceanografía, 2011
Benzocaine, 2-phenoxyethanol and MS-222 were tested as anaesthetics for several handling procedures with spotted rose snapper Lutjanus guttatus broodstock. Significant differences in time for induction and recovery were found with specific doses, as well as a direct correlation between the dose and the induction time.

Hormone-induced spawning of wild and captive-grown spotted rose snapper Lutjanus guttatus using carp pituitary suspension and human chorionic gonadotropin

open access: yesCiencias Marinas, 2011
Hormone-induced spawning of the spotted rose snapper Lutjanus guttatus was studied using wild and cage-grown fish. Carp pituitary suspension (CPS) and human chorionic gonadotropin (hCG) were assessed.

The Standard Deviation Structure as a New Approach to Growth Analysis in Weight and Length Data of Farmed Lutjanus guttatus

open access: yesFishes, 2021
In the present study, size-at-age data (length and weight) of marine cage-reared spotted rose snapper Lutjanus guttatus were analyzed under four different variance assumptions (observed, constant, depensatory, and compensatory variances) to analyze the ...

Benchmarking of early ontogeny parameters as predictors of the first-feeding larvae vitality in spotted rose snapper Lutjanus guttatus

open access: yesAquaculture Reports, 2023
A common problem in marine fish hatcheries is the lack of functional embryonic parameters reliably predicting favorable larval outcomes. Embryos characterized as high-quality by typical assessment methods frequently result in weak larvae with high ...
