Resumen en inglés

Increased connectivity between coastal lagoons and the sea is expected to entail a greater proportion of marine species in the former. Chetumal Bay, estuary of the Hondo river into the Caribbean, had a limited access to the sea until the opening of the Zaragoza Canal. We sought changes in the fish community from 1999–2001 (just after an expansion of the canal) to 2015–2018. The same fishing gear was used, in the same localities, during all seasons. Total fish abundance and mean local richness decreased, although total abundance increased in the polyhaline zone. Diversity was greater in the oligohaline zone in 1999–2001, and in the mesohaline zone in 2015–2018. Three guilds were absent in 2015–2018: Medium-sized herbivores, large piscivores, and medium-sized planktivores. Abundance of small benthivores decreased by decade; medium-sized piscivores and small planktivores became more abundant in 2015–2018 in the polyhaline zone. These changes may be due to the opening of the channel, but illegal fishing outside the bay may explain the decrease in juveniles of large piscivores, and erosion in the innermost part may be destroying important habitats. Our findings can be a reference for similar situations, as coastal development and climate change interact and affect tropical estuaries.

Resumen en español

Se utilizó un enfoque de métodos mixtos para determinar los movimientos estacionales y regionales del macabí (A. vulpes) en la Bahía de Corozal-Chetumal (CB) y la Costa del Caribe (CC). Se utilizaron entrevistas, cuestionarios, talleres, observación participante y notas de campo para recopilar el conocimiento local sobre tiempo y dirección del movimiento en relación a la estacionalidad, hábitat, alimentación y reproducción. Tambien se utilizaron experimentos de marcado-recaptura para: a) determinar la frecuencia de tallas, abundancia y distancias de migración; b) modelar movimiento y abundancia en asociación a variables bióticas y abióticas; c) modelar movimiento y supervivencia con modelos multi-estado en el programa MARK. Se encontraron tallas significativamente mayores en CC (35 + 4.9 cm) que en CB (media = 28.6 + 4.1 cm), debido a una posible mayor densidad y diversidad de presas en los fondos de pastos marinos de CC. Los movimientos a lo largo de la costa fueron: 1) locales de corta distancia, norte-sur y sur-norte, en ámbitos hogareños (distancias > 3.5 km), asociados con la alimentación y en secas y lluvias (febrero a octubre) durante altas temperaturas, y 2) migraciones de larga distancia (> 10 km) ida y vuela de este-oeste y oeste-este, entre CB y dos sitios de agregación de pre-desove (APD) en el norte de Belice y durante los nortes (noviembre a enero) cuando las temperaturas fueron más bajas. El movimiento resultó en: a) mayor abundancia de tallas pequeñas (<22 cm) en CB durante secas y lluvias y una mayor abundancia de tallas grandes (> 22 cm) en CC durante nortes, y b) menor sobrevivencia en CB que en CC durante nortes debido a la migración. El macabí como una especie sombrilla tiene implicaciones y se recomienda que Belice y México desarrollen una estrategia binacional de conservación y manejo de los hábitats de forrajeo y APD para mantener poblaciones saludables.

Resumen en inglés

Bonefish (Albula vulpes) are an important resource for catch-and-release fishing in the Caribbean Sea. Understanding movements within and between the Caribbean Coast (CC) and Chetumal-Corozal Bay (CB) in Mexico and Belize is crucial for identifying and protecting home ranges, migration routes, pre-spawning and spawning sites. We used a mixed-methods approach to document dynamics of bonefish movement. We collected fishers’ local knowledge (LK) using qualitative methods including workshops, key informant interviews, participant observation and field notes about bonefish seasonal movements. We then used mark-recapture (8816 tagged, 569 recaptured) method to understand bonefish movements by size, location and season. Bonefish were significantly larger in CC than in CB. We documented several seasonal movement patterns. A southward movement within CB during the rainy season was likely driven by salinity changes. This was followed by an eastward long-distance migration during the norths or cold front season between the bay and the Caribbean Sea, likely for spawning, as we document likely spawning readiness, pre-spawning behavior and synchronized to the fore-reef at one of two pre-spawning aggregation sites in a World Heritage Site in the CC of Belize during November and December of 2018. There was then a northward movement during the dry season as a journey back to home ranges. The information presented herein can inform resource management and protected areas planning towards a bi-national conservation and management of bonefish and its habitats.

Resumen en inglés

Bonefish (Albula vulpes) is a socioeconomically important species that supports a data-poor recreational fishery in developing countries. Understanding how environmental variables influence its abundance and movement is important for better decision-making.This study used mark-recapture to examine the association between abiotic (temperature, salinity, wind speed, tides moon phase, and sediment coarseness) and biotic (presence of predators and bottom vegetation) variables with bonefish movement and abundance in Corozal-Chetumal bay and the adjacent Caribbean coast of southern Mexico and northern Belize. We used seinesto capture bonefish, marked 9657 using dart tags and recaptured 595 fish (6.2% recapture rate) during 16 sample periods between January 2016 and February 2018. Marked bonefish size ranged 19.5–56.4 cm and recaptured 23.9–49.4 cm. Total abundance for each seine sample and distance between mark and recapture locations were used in two separate multiple stepwise regression analyses. Movement was negatively associated with temperature and predator presence, while sediment coarseness and moon phase were positively associated. Temperature increases were associated withshort-distance movements. Temperature decreases and high-illumination lunar phases were associated with longer-distance movement and likely related to spawning migrations. Presence of predators, like barracuda, was associated with low bonefish abundances and was likely an adaptive response to form multiple schools of low density by bonefish to avoid predation. These spatiotemporal movement and abundance patterns are recommended to be taken into account in fisheries and protected areas management and to inform the decision-making process in urban and tourism development in coastal habitats.

Resumen en inglés

The Yucatan Peninsula (YP) suffered several marine transgressions and regressions during the Quaternary, thus molding the distribution of its present biota, especially its freshwater fish fauna. The Mayan cichlid (Mayaheros urophthalmus Günther) isa euryhaline fish native to the Atlantic slope of Mexico and northern Central America, including the YP; it is one of the most widespread freshwater species in the region. Herein we discuss a phylogeographic scenario by which the Mayan cichlid may have reached its current distribution in the YP. A Bayesian analysis and minimum spanning network were inferred from two partial mitochondrial genes, Cytochrome b (CYTB) and Cytochrome c Oxidase I (COI). The two fragments showed genetic differentiation among populations (Fst=0.31, p value <0.001). Tajima’s D and Fu 's F revealed a tendency to the expansion of some populations. A consistent ordination of north vs south populations was observed. A spatial analysis of molecular variance (SAMOVA) was performed torecognize putative barriers among populations of M. urophthalmus. A secondary molecular calibration located the window time in which the dispersal event may have occurred during the Pleistocene, around 1 Mya. We determined that a Quaternary dispersal around the old coastlines from the south explains the current distribution of the Mayan cichlid.

Resumen en inglés

A trophic model is presented for the coastal lagoon system Chantuto-Panzacola, Southern Pacific Mexico, with the aim of estimating its degree of development and functionality. Thirty-four functional groups (one for birds, one crocodilians, 20 fishes, nine zoobenthos, two plankton, one detritus) were analyzed using Ecopath’s approach, with species biomass, diet composition, and data of species’ production and consumption. Diet was examined from stomach contents for the 39 most abundant fish species, the rest being determined from literature. Detritus was the most important component of the ecosystem in terms of biomass and flows, whereas diverse groups of zoobenthos linked detritus to upper functional groups. Consumers’ trophic level fluctuated between 2.00 and 4.08, with crocodilians as top predators. The size of the system, in terms of matter flows, was 7,133 g m-² year-¹; this value was greater than those recorded in other estuarine systems. Chantuto-Panzacola has a short geological age and is in an intermediate development stage; however, its youth and immaturity are accompanied by attributes which confer stability and environmental health, such as high productivity, high omnivory, and a great reserve potential that the system uses to face disturbances (overhead). The quality of the model was relatively high with respect to others.

Resumen en inglés

Lionfish are successful invasive predators in the Caribbean region and inhabit a large range of habitats. Our study in the Caribbean has focused on the relationships between the biological characteristics of lionfish particularly their size, their activities and use of those different habitats. In this study, we observed a high number of lionfish individuals, focusing on the behavioural activities and biological traits in relation to different habitats and environmental characteristics. We monitored 793 individuals, recording their activities, biological traits, and habitat characteristics. Our results report that lionfish are not solitary, but frequently form groups for many activities. We provide evidence of differences between lionfish habitat use according to activity, and the size of individual fish. Considering the size is correlated with age, coral reefs appear to be the preferred habitat of older individuals, whereas the youngest lionfish use a diversity of habitats, ranging from mangroves to coral reefs. In addition, this study suggests that predation of lionfish is age-dependent strategy, and depends on time and the tone of the environment. Lionfish do not only use the head-down posture to catch prey but also horizontal and head-up postures. The youngest lionfish hunt mainly in dark areas and during the night while the older fish were observed hunting mostly during the day and in clear areas. These new aspects of lionfish ecology and behaviour are discussed in light of their invasive success.

Resumen en inglés

Marine protected areas (MPAs) conserve diversity and abundance of fish communities. According to the biotic resistance hypothesis, communities with higher diversity and abundance should resist invasions better. To test this idea, the presence of lionfish in two Caribbean MPAs was studied: Parque Nacional Guanahacabibes (PNG) in Cuba and Parque Nacional Arrecifes de Xcalak (PNAX) in Mexico. Selection of these MPAs was based on both their different levels of success with enforcement and different abundances of native fish, with a more abundant native fish fauna at PNG. Underwater visual censuses were used to evaluate both the native fish structure and composition and at the same time distribution and abundance of lionfish. The abundance of potential predators on lionfish was also measured to determine possible effects of lionfish on both the abundance and the size of its prey and competitors. Lionfish showed higher abundance and larger size in PNG compared to PNAX, even though its probable competitors and predators were also more abundant and larger in PNG. Prey abundance and size decreased after the invasion. No correlation was detected between potential predators and lionfish, which might indicate natural predation is not substantial. In PNAX, lower abundance of prey, potential competitors and predators can also be attributed to historical overfishing, but this did not provide an advantage to lionfish. Lionfish were less abundant and reached smaller sizes in PNAX compared to PNG. This work confirms the effectiveness of lionfish culling at PNAX, but does not support the biotic resistence hypothesis that native fish might have controlled this invasive species.
