“…All the tagged individuals remained inside LPB and most of their horizontal movements occurred in a shallow area (1-80 m) in the southwestern part where water temperature was 27-29 ºC. These temperatures coincide with other reported preferential temperatures (Palko et al 1982, Campos et al 1993, Massutí and Morales-Nin 1995, Farrell et al 2014.…”

“…Se marcaron ocho dorados juveniles, pero sólo se siguieron seis de ellos por un periodo máximo de 48 h en verano. Todos los individuos marcados permanecieron dentro de la BLP y sus movimientos horizontales se concentraron en una zona poco profunda (1-80 m) en el suroeste de la bahía y a temperaturas de entre 27 y 29 ºC, lo cual coincide con las temperaturas preferenciales reportadas en otros trabajos (Palko et al 1982, Campos et al 1993, Massutí y MoralesNin 1995, Farrell et al 2014.…”

Horizontal and vertical movements of the common dolphinfish (Coryphaena hippurus) in La Paz Bay, Mexico

ABSTRACT. The common dolphinfish (Coryphaena hippurus) is an important resource for the sport-fishing industry in Mexico. It is captured incidentally by the eastern Pacific purse-seine tuna fishery and in coastal areas by artisanal fisheries. Although it is considered a highly migratory species, only few studies of its movements are available. In this study, the behavior of the common dolphinfish was analyzed by means of acoustic telemetry at three locations within La Paz Bay (southern Gulf of California) from summer to autumn 2013. Acoustic transmitters were attached to six individuals and they were tracked for periods of up to 48 h. Every hour, vertical profiles of temperature and bathymetry were made. To determine the effect of biotic (sex) and abiotic (water temperature and depth, thermocline depth, hour, and bathymetry) variables on the horizontal and vertical movements of tagged organisms, generalized additive mixed models were applied. The results showed a tendency of horizontal movements to the southwestern zone of the bay; two individuals crossed from the eastern to the western side. The average speed was 0.51 m s -1 . The vertical movements showed that the individuals spent 80% of the time above 34 m depth, of which around 45% was spent in the upper 10 m of the water column. During daylight hours they swam in shallow waters (upper 10 m) and at night they performed deeper dives (73 m maximum depth). Biotic and abiotic variables influenced both types of movements; however, bathymetry and temperature largely explained fish movements.Key words: horizontal and vertical movements, Coryphaena hippurus, La Paz Bay, acoustic transmitters. RESUMEN.El dorado (Coryphaena hippurus) es un recurso importante para la pesca deportiva en México. Es capturado incidentalmente por la flota atunera de cerco en el Pacífico oriental y en áreas costeras por la pesca artesanal. Aunque es considerada una especie altamente migratoria, existen pocos estudios sobre sus movimientos. En este estudio se analizaron los movimientos del dorado por medio de telemetría acústica en tres localidades dentro de la bahía de La Paz, parte sur del golfo de California, entre verano y otoño de 2013. Se adhirieron transmisores acústicos a seis individuos y se siguieron durante periodos de hasta 48 h. Cada hora, se hicieron perfiles verticales de temperatura y batimetría. Para determinar el efecto de variables bióticas (sexo) y abióticas (temperatura y profundidad del agua, profundidad de la termoclina, hora y batimetría) sobre los movimientos horizontales y verticales de los organismos marcados, se aplicaron modelos aditivos generalizados mixtos. Los resultados mostraron una tendencia a movimientos horizontales a la zona suroeste de bahía de La Paz; dos movimientos atravesaron la bahía de sureste a suroeste. La velocidad promedio fue de 0.51 m s -1 . Los movimientos verticales indicaron que los individuos estuvieron por encima de los 34 m de profundidad el 80% del tiempo, del cual aproximadamente 45% estuvieron en los 10 m superiores. En horas de lu...

“…These results clearly demonstrate that habitat architecture (i.e., spatial and structural components) of Sargassum influences habitat selection by the aforementioned fauna. Larger fish predators (e.g., yellowfin tuna, dolphinfish) also use Sargassum for a refuge and for prey items, making Sargassum ecologically important for the food web and economically important for the fisheries (Oxenford and Hunte, 1999;Logan et al, 2013;Farrell et al, 2014). Dolphinfish have been reported in a high percentage to be associated with pelagic Sargassum (Farrell et al, 2014).…”

Also, gut analyses show most prey items of the dolphinfish are associated with Sargassum, indicating dolphinfish congregate underneath Sargassum patches (Dooly, 1972;Oxenford and Hunte, 1999).…”

The pelagic Sargassum community represents an excellent model system to advance our understanding of how a complex habitat can influence biotic interactions. This study examined the habitat architecture of pelagic Sargassum fluitans to determine its effects on habitat selection for one shrimp species (Leander tenuicornis) and two fish species (Stephanolepis hispidus and Histrio histrio). Specifically, we manipulated interthallus spacing and depth of Sargassum habitats independently (i.e., in separate experimental trials) to test whether spatial components of habitat architecture influence habitat selection by these animal inhabitants. Additionally, two differing habitats (Sargassum vs intermingled seagrass species, Thalassia testudinum and Syringodium filiforme) were tested to determine whether structural components of habitat architecture influenced habitat selection. Results showed no significant effect of habitat selections for interthallus spacing experiments for L. tenuicornis and S. hispidus. However, H. histrio selected habitats with medium interthallus spacing characteristics in two experiments. All three animals selected habitats with a greater depth aspect. Finally, L. tenuicornis and H. histrio selected habitats with greater structural complexity (i.e., Sargassum habitat). These results demonstrate that habitat architecture (i.e., spatial and structural components) of Sargassum influences habitat selection by the aforementioned fauna and further illustrate that this pelagic macroalga is an essential habitat for multiple species.

“…It lives in tropical and subtropical areas of the Atlantic, Indian, and Pacific Oceans (Massuti, Deudero, Sanchez, & Morales-Nim, 1998;Norton, 2000;CIB, 2007;Merten, Appeldoorn, & Hammond, 2014) and is believed to migrate seasonally to warm areas (mean water temperature of 28°C) (Palko, Beardsley, & Richards, 1982). Coastal distribution and abundance seems to be strongly related to surface temperature and distance from temperature fronts (Farrel, Boustany, Halpin, & Hammond, 2014;Furukawa et al, 2014). The dolphinfish has a high growth rate and fast sexual maturity (Alemany & Massuti, 1998;Castro, Santiago, Hernandez-Garcia, & Pla, 1999), which may be associated with physiological adaptations for a pelagic predator (Benetti, Brill, & Kraul, 1995).…”
