Summary: Lipid oxidation in feeds can negatively affect the health and rearing performance of juvenile marine fish. Increasing intake of oxidized lipids decreases survival, growth rate, and liver metabolism, while also altering lipid metabolism and blood cell fragility. These results indicate the importance of proper handling and storage of feeds to maintain their nutrition quality.

Summary: A common problem in marine fish hatcheries is the lack of reliable parameters for predicting larval outcomes. This study aims to determine the most reliable predictor of vitality for first-feeding larvae of L. guttatus. The results show that blastomere morphology score is the only parameter positively correlated with larval vitality.

Summary: This study found that oceanographic conditions and habitat characteristics have an impact on genetic structure in marine species, using Lutjanus guttatus as an example. The Gulf of Panama, as part of the Tropical Eastern Pacific, acts as a barrier to gene flow due to its complex current system and heterogeneous environment. The results suggest that adaptive selection plays a crucial role in population differentiation for Lutjanus guttatus.

Summary: This study assessed the genetic diversity and population genetic structure of the spotted rose snapper in the Tropical Eastern Pacific using 12 microsatellite loci. The results showed high genetic diversity and a panmictic population structure across all sampled sites. The study also discussed the role of larval dispersal, post-recruitment migration, and marine current dynamics in shaping the genetic connectivity of this species.

Summary: The parasite communities of Lutjanus guttatus showed significant spatial and interannual variations over a 10-year period in Mexico. The species composition and community structure of parasites varied between sampling locations and through the years, possibly due to biotic and abiotic factors. However, there was high similarity in parasite species composition at a local level for short-term periods.

Summary: The spotted rose snapper is an important resource in the coastal fisheries of the Gulf of California, showing a narrow trophic niche as a benthopelagic opportunistic carnivorous predator. Significant differences were found in its diet based on sex, size, and season, with quantitative variations in prey consumed. Its trophic plasticity allows it to take advantage of the most available and abundant food resources.

Summary: This study evaluated the effects of diets with varying crude protein-to-precooked cornstarch ratios on the growth performance and blood chemistry parameters of juvenile Lutjanus guttatus. The results showed that the fish were able to digest and metabolize up to 35% of precooked cornstarch without any negative effects on growth performance.

Summary: This study investigated the rearing performance and skin coloration of spotted rose snapper using different diets with various levels of shrimp head meal (SHM) as a replacement for fish meal (FM). The diets containing SHM showed higher growth rates, lower feed conversion ratio values, and improved skin coloration compared to the control diet. The use of up to 30% SHM protein in the diets appears to be a good alternative for more efficient aquafeed production.

Summary: In 2015 and 2016, an unrecognized Francisella sp. was discovered in disease outbreaks in maricultured spotted rose snapper on the Pacific coast of Central America. Polyphasic analysis showed that these bacteria differed from known Francisella spp. The complete genomes of the recently described Francisella marina strains have now been released.

Summary: Skin-associated bacteria have been found to inhibit infection by the fungal pathogen Batrachochytrium dendrobatidis (Bd) in amphibians, and are related to Bd infection intensity. However, the microbial dynamics regulating Bd intensity are still not fully understood. Analysis of Bd infection and skin-associated bacteria from two co-occurring amphibian species in central Mexico revealed a negative relationship between bacterial richness and relative abundance of inhibitory Bd bacteria with Bd infection intensity, despite high prevalence of Bd in the host species. No dead or sick individuals were found during field surveys, suggesting that the individuals were able to survive and thrive with enzootic infections of Bd and their microbiota.
