“…At locations where the number of prey items consumed by the species was lower, the ecosystems presented more homogeneous conditions; for example, L. guttatus individuals in Costa Rica are surrounded by mangroves, whereas in Nayarit, Mexico, the area has sandy bottoms and rocky substrates (Tripp-Valdez and Arreguín-Sánchez 2009). However, off Guerrero, Mexico (Rojas-Herrera and Chiappa-Carrara 2002) where the number of prey items consumed by the species was greatest, the species richness could be due to the heterogeneity of the ecosystem, which includes rocky substrates, reef patches, soft bottoms, and a wide continental platform with variable oceanography dynamics (Palacios-Salgado et al 2014), which allows the species to feed on a greater number of prey items. The study area in the presently reported investigation (Santa Rosalía, BCS) was characterized by sandy and rocky bottoms, where oceanographic processes such as the dominance of regional winds that favor upwelling led to large numbers of prey species such as S. -3 (Gómez-Gutiérrez et al 2010).…”

The spotted rose snapper, Lutjanus guttatus (Steindachner, 1869), is an important resource for the coastal fisheries of the Gulf of California, mainly due to its high commercial value. Despite this, there are no management measures for this species, owing in part to a lack of information on its basic biology and its trophic ecology in the area. In this context, the presently reported study had as objective to describe the feeding habits of L. guttatus through stomach content analyses, as well as to describe possible changes linked to sex, size, and season. Specimens were caught monthly from June 2016 to September 2017 with gillnets in Santa Rosalía, BCS, Mexico. The abundance, weight, and frequency of occurrence of each prey were assessed, and these parameters were integrated into the index of relative importance (%IRI) to determine the importance of each prey item in the L. guttatus diet. The Levin’s index was used to assess the trophic niche width of the species, the feeding strategy was evaluated using Costello’s graphic method and the trophic level was calculated. Finally, to establish whether there were significant differences in the diet by sex, size, or season a PERMANOVA test was used with a 95% confidence level. A total of 202 L. guttatus stomachs were analyzed, 191 of which contained food. A total of 26 prey items were identified. According to the %IRI, the most important prey were the teleost fishes Harengula thrissina (Jordan et Gilbert, 1882) (45.7%) and Sardinops sagax (Jenyns, 1842) (34.8%), the euphausiid Nyctiphanes simplex (13.4%), and the crustacean Penaeus spp. (5.6%). The PERMANOVA analysis resulted in significant differences between the analyzed categories; however, there were no significant differences in the interactions among the categories. According to Levin’s index, L. guttatus had a narrow trophic width, with changes in the main prey consumed by the different categories. According to our results, L. guttatus can be considered a benthopelagic opportunistic carnivorous predator with a narrow trophic niche, presenting mostly quantitative variations in its diet according to sex, size, and season. Its trophic plasticity allows it to take advantage of the most available and abundant food resources.

“…Marine ichthyofauna in estuarine-lagoons of the GT is composed of many species widely distributed between the provinces Cortés and Panamic, dominating species of tropical derivation over those of temperate origin. Although the GT is located at a critical point of the Central American gap, this has a limited effect on the fish fauna at the regional level in the Mexican tropical Pacific (Palacios-Salgado et al, 2014;Robertson & Cramer, 2009). From the standpoint of the continental biogeography, the Pacific slope provinces in northern and nuclear Central America are characterized by a low representation of primary derivation species (Cichlidae and Poeciliidae are the most speciose families), dominating components of marine and neotropical origin (Lozano-Vilano & Contreras-Balderas, 1987;Matamoros et al, 2015;Myers, 1966).…”

A checklist of fishes recorded from Mar Muerto, La Joya-Buenavista, and Los Patos-Solo Dios lagoon-estuarine systems, northeastern Gulf of Tehuantepec, Mexico is presented. Fish samples were collected through 34 stations using several kinds of fishing gear, between April 2007 and May 2016. The checklist includes 2 classes, 19 orders, 52 families, 87 genera, and 120 species. The best-represented families are Carangidae (9 species), Gerreidae (7), and Engraulidae (6). The Mar Muerto system had 89 species, followed by La Joya-Buenavista with 76; in Los Patos-Solo Dios, only 41 species were recorded, perhaps due to a lower marine influence. Based on their ecological affinities, 43% of the fishes belong to marine stenohaline component, 42% to the marine euryhaline component, 11% are of freshwater derivation, and 5% are estuarine residents. The ichthyofauna showed high affinities to the Panamic province (80.7%) followed by Mexican (79.8%) and Cortés (73.1%) provinces. Nine species (8 native and 1 exotic) are added to the known continental fish fauna of the state of Chiapas.
