In September 1986, we collected neuston (1 x 2 m, 0.947 mm mesh) and surface chlorophyll a samples and hydrographic data at 46 stations around the discharge plume of the Mississippi River. Transects were positioned so that the 3 water masses in the plume area -plume water, Gulf of Mexico shelf water and frontal water (a mixture of the former 2) -were sampled. The plume was represented by a shallow lens of water < 3 4 '10 salinity and < 29 "C resting atop warmer (> 29 "C) and more saline (> 34 %) Gulf of Mexico shelf water. Strong turbidity fronts with a scale of 50 to 100 m form, relax and reform approximately at tidal frequencies within the frontal region that has a larger scale of 6 to 8 km. Total ichthyoplankton catch per tow, individual surface chlorophyll a values and macrozooplankton displacement volumes were all significantly greater in frontal waters than adjacent Gulf of Mexico shelf or plume waters Hydrodynamic convergence at the continually forming and relaxing turbidity fronts most likely accounts for concentrated neustonic ichthyoplankton, and at least partially for high macrozooplankton values as well, in frontal waters. Elevated macrozooplankton displacement volumes in frontal waters may also result from higher rates of proliferation of macrozooplankton biomass. High primary production in frontal water is probably due to the mixing of nutrientrich, but turbid, plume water (where photosynthesis is light limited) with clear, but nutrient-poor, Gulf of Mexico shelf water (where photosynthesis is nutrient limited) creating favorable phytoplankton growth conditions. Concentrations of ichthyoplankton and zooplankton offer rich trophic resources that some species utilize to gain superior growth. Faster growth will lead to increased survival and recruitment (because larvae pass through the period of greatest vulnerability to predation by gapelimited predators more quickly) if larval growth is increased disportionately to larval mortality from predation.

“…Frontal zones and eddy fields have been found as features attracting fish and larvae, and creating patchy zones of high phytoplankton concentrations (Kirobe et al 1986;Lefevre 1986;Marshall et al 1981;Sabates, Maso 1990). For instance, Laurs et al (1984) found that albacore catch rates were highest in warm and blue oceanic waters, as measured from satellites, associated with the boundary (front) between oceanic and coastal waters.…”

Sustainable use of marine resources requires effective monitoring and management of the world’s fish stocks. Acoustic and electromagnetic remote sensing techniques are being used to help manage fisheries at sustainable levels, while also guiding fishing fleets to locate fish schools more efficiently. Fish tend to aggregate in ocean areas that exhibit conditions favored by specific fish species. Some of the relevant oceanographic conditions, such as sea surface temperature, ocean color (productivity) and oceanic fronts, which strongly influence natural fluctuations of fish stocks, can be observed and measured by remote sensors on satellites, aircraft and ships. The remotely sensed data are provided in near-real time to help fishermen save fuel and ship time during their search for fish, to modelers who produce fisheries forecasts, and to scientists who help develop strategies for sustainable fisheries management. This article describes how acoustic, optical and radar sensors on ships, satellites and aircraft are used with forecast models to improve the management and harvesting of fisheries resources.

“…Thus, spawning aggregations will tend to yield "larval aggregations" in these warmer water spawners. Pelagic species, such as sprat and horse mackerel, are not as tightly coupled to topographic (bottom) features for spawning compared to demersal fish species, such as cod and plaice, but may target mesoscale (20 to 200 km) hydrographic structures such as frontal zones due to aggregations of potential prey in these areas (Kiørboe et al, 1988;Riegman et al, 1990;Munk et al, 1999;Floeter, 2005). Moreover, in contrast to demersal species such as plaice and cod that fuel spawning from lipid stores accrued during summer feeding, small pelagic fish can augment the energy utilized for reproduction by feeding during the spawning season.…”

“…For example, tidal-mixing areas and frontal zones can be extremely productive habitats that support a high biodiversity of marine fauna including relatively dense aggregations of larval fish, their prey and their predators (Kiørboe et al, 1988;Riegman et al, 1990;Munk et al, 1999;Floeter, 2005). These physical features of the environment are directly impacted by changes in climate forcing (e.g.…”

SUMMARY:We employed 3-D biophysical modeling and dispersion kernel analysis to explore inter-annual and interspecific differences in the drift trajectories of eggs and yolksac larvae of plaice (Pleuronectes platessa), Atlantic cod (Gadus morhua), sprat (Sprattus sprattus) and horse mackerel (Trachurus trachurus) in the North Sea. In this region, these four species exhibit peak spawning during the boreal winter, late winter/early spring, late spring/early summer, and mid-summer respectively, but utilize the same spawning locations (our simulations included Dogger Bank, Southern Bight and the German Bight). Inter-annual differences in the temperature history, and an increase in the area of dispersion and final distribution at the end of the yolksac phase were more pronounced (and related to the North Atlantic Oscillation) for winter-and early spring-spawners compared to late spring/summer spawners. The progeny of the latter experienced the largest (up to 10-fold) inter-annual differences in drift distances, although absolute drift distances were modest (~2 to 30 km) when compared to those of the former (~ 20 to 130 km). Our results highlight the complex interplay that exists between the specific life history strategies of the different species and the impacts of the variability in (climate-driven) physical factors during the earliest life stages of marine fish.Keywords: IBMs, marine fish, life history strategy, drift, temperature, water currents. RESUMEN: DIFERENCIAS INTERANUALES E INTERESPECÍFICAS EN LA DERIVA DE HUEVOS Y LARVAS LECITOTRÓFICAS EN EL MAR DENORTE: APROXIMACIÓN A TRAVÉS DE UN MODELO BIOFÍSICO. -En este trabajo utilizamos un modelo 3-D físico-biológico y un análisis de dispersión del núcleo para investigar las diferencias interespecíficas e interanuales en las trayectorias de la deriva de huevos y larvas lecitotróficas de la solla (Pleuronectes platessa), el bacalao Atlántico (Gadus morhua), el espadín (Sprattus sprattus) y el jurel (Trachurus trachurus) en el Mar del Norte. En esta región, las especies estudiadas muestran distintos picos de distintos desoves en el tiempo: invierno boreal, invierno tardío/primavera temprana, primavera tardía/verano temprano y mitad del verano, respectivamente, aunque comparten las mismas zonas de desove. Las simulaciones efectuadas corresponden a tres de estas zonas: Dogger Bank, Southern Bight y German Bight. Los resultados mostraron diferencias interanuales en la temperatura experimentada por las larvas, en el área de dispersión y en el patrón de distribución al final del estadio lecitotrófico, que fueron más evidentes en el bacalao Atlántico, en comparacion con el espadín. Así mismo, estos factores estuvieron correlacionados con la Oscilación del Atlántico Norte. La progenie del espadín, además, mostró la mayor variación interanual en la distancia de dispersión, siendo hasta 10 veces mayor, aunque la distancia absoluta alcanzada fue relativamente modesta (~2-30 km) en comparación con la observada para el bacalao Atlántico (~20-130 km).
