Relationship of Acanthuridae and Scaridae with biotic and abiotic factors in western CubaAbstract
Acanthuridae y Scaridae son familias de peces herbívoros que constituyen los principales controladores de macroalgas en arrecifes coralinos. Sobre su distribución y abundancia inciden factores bióticos y abióticos, naturales u originados por el hombre. El objetivo de esta investigación fue analizar la relación de la densidad y biomasa de Acanthuridae y Scaridae con variables bióticas y abióticas en arrecifes con diferente nivel de protección del occidente de Cuba. Para esto, se usaron comparaciones múltiples de media por rangos y pruebas de correlaciones por rangos de Spearman en tres localidades muestreadas entre 2014 y 2017: Municipio Playa (La Habana), Bahía de Cochinos (Matanzas) y María la Gorda (Pinar del Río), las dos últimas ubicadas en Áreas Marinas Protegidas. Las Áreas Marinas Protegidas analizadas mostraron los indicadores más satisfactorios de Scaridae, que disminuyeron en las localidades con impacto antrópico. La contaminación y la presión de pesca en La Habana, mantenida por años, parecen ser las causas principales de la ausencia de adultos de Scaridae. La mayor densidad y biomasa de peces carnívoros (familia Lutjanidae) pudieran ser factores limitantes para la familia Acanthuridae, la cual exhibió mayor densidad y biomasa en sitios con mayor disponibilidad de alimento (macroalgas de los géneros Sargassum, Amphiroa y Galaxaura), menor complejidad topográfica y mayor antropización.Acanthuridae and Scaridae are families of herbivorous fishes that are the main controllers of macroalgae in coral reefs. Its distribution and abundance are affected by biotic and abiotic factors, natural or originated by man. The objective of this research was to analyze the relationship of the density and biomass of Acanthuridae and Scaridae with biotic and abiotic variables in reefs with different levels of protection in western Cuba. For this, multiple comparisons of means by ranks and Spearman’s rank correlation tests were used in three localities sampled between 2014 and 2017: Municipio Playa (Havana), Bahía de Cochinos (Matanzas) and María la Gorda (Pinar del Rio), the last two located in Marine Protected Areas. The Marine Protected Areas analyzed showed the most satisfactory indicators of Scaridae, which decreased in localities with anthropogenic impact. Pollution and fishing pressure in Havana, maintained for years, seem to be the main causes of the absence of Scaridae adults. Higher densities and biomass of carnivorous fishes (Lutjanidae family) could be limiting factors for the Acanthuridae family. Acanthuridae exhibited higher density and biomass in sites with greater food availability (macroalgae of the genera Sargassum, Amphiroa and Galaxaura), less topographic complexity and more anthropized.
