“…For example, Striped Bass are known to use estuaries in the region during the summer (Tupper and Able, 2000;Ferry and Mather, 2012). The same is true for Bluefi sh Sagarese et al, 2011), Summer Flounder (Sackett et al, 2007;Sagarese et al, 2011), and Weakfi sh (Taylor, 1987;Turnure 2010). Therefore, our fi ndings from the inner shelf should be viewed with this qualifi cation in mind.…”

Abstract-Piscivorous fishes, many of which are economically valuable, play an important role in marine ecosystems and have the potential to affect fish and invertebrate populations at lower trophic levels. Therefore, a quantitative understanding of the foraging ecology of piscivores is needed for ecosystem-based fishery management plans to be successful. Abundance and stomach contents of seasonally co-occurring piscivores were examined to determine overlap in resource use for Summer Flounder (Paralichthys dentatus; 206-670 mm total length [TL]), Weakfish (Cynoscion regalis; 80-565 mm TL), Bluefish (Pomatomus saltatrix; 55-732 mm fork length [FL]), and

“…The use of surgery is often a good option in long-term telemetry studies, as internal tags can remain in the fish for years without giving problems (Jepsen et al, 2002). In addition, in some studies that employed external tags, a large number of tags were found to fall off (Sackett et al, 2007). However, the surgical implantation technique is complicated and has been associated with a high risk of mortality, infection and tag loss, all of which have been used as arguments in favour of external implantation (Jepsen et al, 2002).…”

“…Golet et al (2006) filtered the original positions to improve the positions obtained with complex and already very precise telemetry technology (RAPT system). However, Sackett et al (2007), with manual telemetry systems similar to those employed here, selected reception strengths of 120 dB, with gains ≤12 dB to obtain resolutions at a scale of metres.…”

SUMMARY: Labrus bergylta, Dicentrarchus labrax and Conger conger are common predators of northeast Atlantic coastal ecosystems and are studied here for the first time with ultrasonic telemetry in their natural environment. We demonstrate the viability of using this technology with these species and used movement information to obtain preliminary short-term results on site fidelity, diel activity patterns and home range sizes. Two complementary telemetry methods were used: manual and automatic tracking along a stretch of coast characterized by its high wave exposure (A Coruña, NW Spain). C. conger stayed in the area for the longest periods of time (17 days), occasionally leaving their refuges at dusk or during the night to search for food. Their home range was very small (604 m 2 ). L. bergylta were not detected by the automatic receivers but the size of their home range (between 2874 and 5184 m 2 ), shows that they are highly sedentary with very limited movements. D. labrax left the area for the longest periods (9 days) and were detected during both night and day. Their home range was the largest (up to 26396 m 2 ), evidencing complex spatial behaviour on a large scale.Keywords: coastal predatory fish, habitat use, site fidelity, home range, diel activity, tagging, telemetry, VR2, VR100. RESUMEN: Movimientos de tres grandes peces depredadores costeros del Noreste Atlántico: un estudio preliminar mediante telemetría. -Labrus bergylta, Dicentrarchus labrax y Conger conger son depredadores habituales de los ecosistemas costeros del Noreste Atlántico que en este trabajo se estudian por vez primera mediante telemetría ultrasónica en el medio natural. Se demostró la viabilidad del uso de esta tecnología con estas especies y la información sobre sus movimientos se usó para obtener resultados preliminares a corto plazo acerca de la fidelidad al hábitat, la temporalidad diaria de la actividad y el tamaño del área vital. Se emplearon complementariamente dos métodos de telemetría: seguimiento manual y automático en un tramo de costa caracterizado por su elevado grado de exposición al oleaje (A Coruña, NW Spain). Los C. conger permanecieron en el área durante los períodos más largos (17 días), abandonando periódicamente sus refugios al atardecer o durante las noches para buscar alimento. El tamaño de su área vital fue muy pequeño (604 m 2 ). Los L. bergylta no fueron detectados en los receptores automáticos, pero el tamaño de su área vital (entre 2874 y 5184 m 2 ), evidencia un elevado grado de sedentarismo y movimientos muy limitados. Por el contrario, los D. labrax abandonaron el área durante los intervalos más prolongados (9 días), detectándose igualmente durante el día o la noche. Su área vital fue la de mayor tamaño (hasta 26396 m 2 ), evidenciándose un comportamiento espacial complejo y a gran escala.Palabras clave: peces depredadores costeros, uso del hábitat, fidelidad al hábitat, área vital, actividad diaria, marcaje, telemetría, VR2, VR100.

“…In comparison with the other boats, boat A fished in deeper waters further offshore, where larger and heavier fish were more available (Figure 1). The pattern of smaller fish occurring inshore and in estuaries and larger fish occurring further offshore is well documented (Able and Kaiser 1994;Szedlmayer and Able 1996;Sackett et al 2007).…”

Evaluating Catch, Effort, and Bag Limits on Directed Trips in the Recreational Summer Flounder Party Boat Fishery

The summer flounder Paralichthys dentatus is one of the most sought‐after recreational fish along the mid‐Atlantic coast of the United States. This fishery is primarily a consumptive fishery. The stock has been successfully rebuilding but remains below statutory rebuilding goals. Managers accordingly have restrained the annual quota primarily by increasing size limits, with a resulting increase in discard mortality. The purpose of this study was to evaluate new approaches to bag and size limits that minimize discard mortality while increasing angler satisfaction within the constraints of promulgated catch quotas. Three alternative management scenarios (slot limit, reduced minimum size, and cumulative size scenarios) were tested on party boats from New Jersey and New York. Total catch (by number) was lowest for control fishing trips (2006 state regulation) and higher for all three experimental scenarios because the experimental scenarios resulted in a greater number of kept fish. Discard‐to‐catch ratio (by fish weight and number) was highest for control trips, and landings (by weight and number) were lowest for the control scenario. Recreational fishermen operating under the reduced minimum size and cumulative size scenarios kept the most fish; these scenarios had the lowest discard‐to‐catch ratios. The slot limit scenario was intermediate in the discard‐to‐catch ratio and also in the number of kept fish. All three alternative management scenarios resulted in landing more fish under a biomass‐neutral fishery to retain catch within allocation limits. Relative to 2006 legal conditions, the alternative scenarios produced proportional increases in landings by a factor of 1.75 to 2.09, while reducing discard mortality by 41–63% and maintaining the same total fishing mortality (landings plus discards) by weight.
