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. Each procedure demanded specific anaesthesia levels where the stage of deep anaesthesia should not be surpassed. The most effective agent for inducing deep anaesthesia was MS-222, with the least amount of time required for induction and recovery when using 100 mg l -1. It was followed by 250 μl l -1 of 2-phenoxyethanol, which was less costly.

Egg handling and incubation are short but important procedures in juvenile fish production technologies. To determine appropriate practices for egg handling and incubation in the spotted rose snapper Lutjanus guttatus (Steindachner, 1969), three experiments were carried out in 100-L fiberglass conical cylinder tanks. Eggs were incubated with and without water flow (30% volume/h), at two densities (250 eggs/L and 1000 eggs/L), and with and without formaldehyde 10-ppm prophylactic treatment for 1-h prior to incubation. Total hatching and larvae survival percentages were not significantly different between the treatments with and without water flow, while results for larvae survival at hatching time and 48 h post-hatch stage were significantly better without water flow. For incubation at two different densities, all examined performance indexes were significantly better at the lower density, except for larvae survival at 48 h after hatching. The eggs with and without prophylactic treatment were not significantly different in all analyzed survival indexes at hatching time and 48 h post-hatch. Total length was significantly different in all treatments at hatching time and 48 h post-hatch, except in the incubation without water flow. The longest larvae were obtained in the experiment with prophylactic treatment.

Juvenile seedstock availability and costs are some of the main biological aspects to be considered on species for intensive culture assessment studies, together with market importance and performance under culture conditions, especially the growth rate and yields. A juvenile yield index (JYi) is described, as one of the judgment indicator of juvenile efficiency utilization on edible size culture production of tropical marine fishes. This index is expressed asthe number of juveniles required per metric ton per year, and combines fish growth rate during grow-out, survival, and commercial size at harvest. The JYi could be combined with production costs and wholesale prices, to estimate a juvenile gross profit index (JGPi), and expressed in terms of estimated gross profit per juvenile number required per ton produced per year.

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. F2 juveniles were reared until their sexual maturity and spawned at the same laboratory. Result indicate that a reliable supply of laboratory reared spawners can be achieved, avoiding the wild spawners dependence and allow the development of selection and genetic improve programs.

For incubation of eggs, prophylactic treatments are applied to minimize negative effects of microorganisms on eggs and larvae. The effects of treatments with formaldehyde, acriflavine and glutaraldehyde to spotted rose snapper Lutjanus guttatus eggs, were studied. Reduction of colony forming units (CFU), the percentages of hatching, live larvae, live normal larvae and larval size, were studied. Best treatment with significant reduction of CFU, but without observable effects on the eggs with controls was with acriflavine at 5 ppm.
