Hormone induced spawning of red snapper, Lutjanus campechanus

Aquaculture, 1983
Abstract Red snapper, Lutjanus campechanus , were induced to ovulate following injections of Human Chorionic Gonadotropin (HCG). Females were injected initially with 1.1 IU/g body weight. When subsequent injections were necessary, 0.55 IU/g of body weight was used. Ovulation occurred between 42 and 56 h following injection.

Substrate preference in age-0 red snapper, Lutjanus campechanus

Environmental Biology of Fishes, 1997
We tested age-0 red snapper, Lutjanus campechanus, for sand or shell substrate preference in a circular tank (1.5 m diameter × 0.6 m deep). The test tank was divided into two equal areas of whole oyster shell or sand substrates. All trials were video taped for 20 to 25 min.

Validation of annual periodicity in otoliths of red snapper, Lutjanus campechanus

Environmental Biology of Fishes, 2011
The periodicity of otolith growth increments (opaque and translucent zones) from adult red snapper (Lutjanus campechanus) was examined through a mark and recapture study (2005–2010), and laboratory holding of hatchery reared red snapper over a 2 year period (2002–2004).

Forecasting dynamics of red snapper (Lutjanus campechanus) in the U.S. Gulf of Mexico

Fisheries Research, 2017
Abstract Understanding dynamics and stock structures of fish is particularly relevant to assessments and management of marine living resources. Using the nonparametric, nonlinear time series (NLTS) approach, we modeled dynamics of red snapper ( Lutjanus campechanus ) represented by time series of two fisheries-independent abundance indices and two ...

Oxygen Consumption, Energy Expenditure, and Growth of the Red Snapper (Lutjanus campechanus)

Transactions of the American Fisheries Society, 1979
Abstract Daily weight increases of captive 1–2-year-old red snappers over a period of 300 days were approximately 0.45% of body weight—a value which agreed closely with estimated daily weight increases in a wild population. Respiratory metabolism for 1–2-year-old red snappers swimming at 0.5 km/hour was 89 mg O2 kg−1 hour−1 at 20 C, and resting ...

Home range and movement patterns of red snapper (Lutjanus campechanus) on artificial reefs

Fisheries Research, 2011
Abstract Red snapper (Lutjanus campechanus) are associated with artificial habitats in the Gulf of Mexico (GOM). However, fine-scale movements and use of artificial reefs by red snapper over diel periods is unclear. Both manual and passive telemetry were used to examine fine-scale movement patterns and residence time of red snapper around artificial ...

The webbing reef: a tool used in the study of juvenile red snapper (Lutjanus campechanus)

Oceans '02 MTS/IEEE, 2003
The primary purpose for requiring shrimp trawlers to use bycatch reduction gear in the U.S. Gulf of Mexico is to reduce the incidental capture and mortality of juvenile red snapper (Lutjanus campechanus). Developing effective bycatch reduction devices (BRDs) for this purpose requires a good understanding of juvenile snapper behavior and their reaction ...
