“…This species is reserved for sport fishing within 50 nautical miles measured from the territorial sea baseline (DOF 1995). It is also caught incidentally by the purse-seine and artisanal fisheries (Aguilar-Palomino et al 1998, Madrid and Beltrán-Pimienta 2001, Martínez-Rincón et al 2009). …”

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...

“…Their distribution is limited by the 20°C isotherm (Palko et al, 1982), and seasonal and interannual changes in sea-surface temperature (SST) influence their local catch rate and abundance (Kraul, 1999;Norton, 1999;Zúñiga-Flores et al, 2008); additionally, their distribution seems to be influenced by prey availability and metabolic needs for sustaining their rapid growth (Schwenke, 2004). These fish are opportunistic predators and feed on a wide spectrum of prey, which includes several species of bony fish, cephalopods, and crustaceans (Aguilar-Palomino et al, 1998;Massutí et al, 1998;Oxenford, 1999;Sakamoto and Kojima;TrippValdez et al, 2010).…”

“…Because of its circumtropical and subtropical distribution and its biological characteristics (fast growth, early maturity, and high fecundity), high catch rates of dolphinfish are reported all over the world, where they are targeted by commercial and recreational fisheries (Martínez-Rincón et al, 2009;Farrell et al, 2014). In the Mediterranean Sea, dolphinfish are caught by using a special type of net (called llampuguera) around fish-aggregating devices (Massutí and Morales-Nin, 1997), and in the western Atlantic Ocean, they are caught commercially by using pelagic longlines, and recreationally by rod and reel (Farrell et al, 2014).…”

In South America, it is fished industrially in the Pacific Ocean waters by using surface nets at night near Colombia and Venezuela (Lasso and Zapata, 1999) and by the longline fleets of Ecuador and Costa Rica (Patterson and Martinez, 1991;Campos et al, 1993).…”
