Sicklefin devilray and common remora prey jointly on baitfish Environ. Biol. Fish. (IF 1.516) Pub Date : 2020-07-08 S. Solleliet-Ferreira, B.C.L. Macena, B.J.L. Laglbauer, A.F. Sobral, P. Afonso, J. Fontes
Devil rays are considered pelagic filter-feeders but direct observation of their foraging in the wild is very scarce and their feeding ecology is known essentially from indirect methods. On September 2018, a group of 16 sicklefin devil rays were observed preying on bait balls of longspine snipefish (Macroramphosus scolopax), together with their associated common remora (Remora remora), at Princess

Genetic connectivity of black drum ( Pogonias courbina ) stocks in the southwestern Atlantic Ocean Environ. Biol. Fish. (IF 1.516) Pub Date : 2020-06-27 Renan Costa Machado, Maria Cristina da Silva Cortinhas, Maíra Carneiro Proietti, Manuel Haimovici
The delimitation of fishery stocks is an important aspect for the development and implementation of fishery stock management and sustainable use programs. Genetic analyses can provide useful information for the definition of population units, migration rates and changes in effective population sizes over long time frames. The black drum Pogonias courbina (Lacepede, 1803) is a marine fish that inhabits

Overwinter survival, age, and growth of juvenile tarpon ( Megalops atlanticus ) in a shallow, tidally-restricted habitat in South Carolina Environ. Biol. Fish. (IF 1.516) Pub Date : 2020-06-26 Marvin M. Mace, Matthew E. Kimball, Garrett M. Elmo, Derek P. Crane
Early life stage tarpon (Megalops atlanticus) have been collected in the western Atlantic Ocean north of Florida where it has been assumed that individuals migrate from estuarine areas at the onset of winter because water temperature during winter is too low for survival. However, there is anecdotal evidence of juvenile tarpon present during winter in this region. We conducted a tag-recapture study

Potential poleward distribution shift of dolphinfish ( Coryphaena hippurus ) along the southern California Current System Environ. Biol. Fish. (IF 1.516) Pub Date : 2020-06-25 Christian Salvadeo, Daniel M. Auliz-Ortiz, David Petatán-Ramírez, Héctor Reyes-Bonilla, Antonina Ivanova-Bonchera, Eduardo Juárez-León
The dolphinfish (Coryphaena hippurus Linnaeus, 1758) is an epipelagic top-predator that is globally distributed in tropical and subtropical waters. In the Eastern Tropical and Subtropical Pacific, this fish represents a target species for commercial and recreational fisheries. Climate change is affecting biodiversity, and a poleward expansion was suggested for dolphinfish due to its affinity for warm

Age, growth, and gonadal condition of the Giant mottled eel, Anguilla marmorata , in Okinawa-Jima Island, Japan Environ. Biol. Fish. (IF 1.516) Pub Date : 2020-06-23 Tomohiro Kita, Katsunori Tachihara
Age, growth, and gonadal condition of the Giant mottled eel, Anguilla marmorata, were estimated from 303 specimens collected at Okinawa-jima Island, Japan. Otolith opaque zones that formed every year correlated with high water temperature and were thought to be annual rings. The growth of this species differed between males and females, and females were longer lived and larger than males. The mean

Meristic and morphological differentiation of Orestias species (Teleostei; Cyprinodontiformes) from the southern Altiplano Environ. Biol. Fish. (IF 1.516) Pub Date : 2020-06-22 Sergio Scott, Pablo Rojas, Irma Vila
Orestias is an endemic fish genus of lacustrine and lotic systems distributed on the Andes highland region (Altiplano) of Peru, Bolivia and Chile (9°S to 22°S). Based on morphological characters, taxonomic studies have recognized seven species on the Chilean western southern Altiplano region (17°S - 22°S). The current geographical distribution of Orestias would be associated with historical vicariant

Head morphometry of Orestias (Cyprinodontiformes). Response to extreme Southern Altiplano systems? Environ. Biol. Fish. (IF 1.516) Pub Date : 2020-06-22 Pablo Rojas, Sergio Scott, Ignacio Tobar, Úrsula Romero, Irma Vila
The distribution of Orestias (Cypriniforms) species in the southern western Altiplano (17ºS-22ºS) is allopatric; the seven species described inhabit different freshwater systems with extreme climatic characteristics and different ecological conditions, factors that would have enhanced interspecific differentiation. To analyze their head differences we compared jaw morphology of eight species of Orestias
