“…Variability in the timing of spawning coupled with seasonal warming is likely responsible for interannual differences in end-of-year estimates of size of 0-group cod (Kondratovich & Lablaika 1989). Future temperature-related studies migh.t include investigating temperature effects in mesocosm or laboratory studies, deriving otolith-and length-based growth rates from field collected specimens, and reconstructing environmental conditions experienced by larvae from otolith microchemistry (Campana et al 1995, Townsend et al 1995.…”

ABSTRACT. We review eastern Baltic cod literature to identify areas for future research involving egg and larval stages. Egg and larval abundances have been estimated for several decades in all of the major spawning areas. Using a subset of the available data we show that the timing of peak egg abundance in one of these areas (Bornholm Basln) vanes seasonally by at least 2 mo. Trends in egg and larval abundance over time are not obvious due to differences In gear type, sampling intensity, and survey timing relative to spawning dates Interannual differences in larval transport away from spawning areas may also contribute to variability in abundance estimates The results of broad-scale zooplankton surveys suggest that the abundance and types of potential prey in the Baltic Sea are similar to those in other regions and perhaps suitable for moderate-to-fast larval growth However, few systematic surveys have described food concentrations at appropriate scales for cod larvae, and the species composition of larval diets is unknown. Growth rates for Baltic cod larvae have not been measured and cannot be compared with rates in other areas or to vanatlons in biotic and ab~otlc factors. Large gaps exist in our knowledge of processes affecting egg and larval growth and survival, but some promising areas of research are indicated. In particular the seasonality of spawning, deep water oxygen concentrations, predation on eggs, and larval food production require further investigation

“…habitat, diet, temperature and depth) that a marine organism has experienced throughout its life history (Radtke et al 1987, Kalish 1991a,b, Gauldie et al 1994, Schwarcz et al 1998. The environmental variation recorded in fish otoliths can subsequently be used as an indicator of the home range and spatial distribution of a fish species, which can have implications for stock structure and fisheries management (Campana et al 1995, Edmonds & Fletcher 1997, Roelke & Cifuentes 1997. In this study, we investigated the use of stable δ 13 C and δ 18 O isotopes in haddock Melanogrammus aeglefinus otoliths as indicators of environmental variation and stock structure in the northwest Atlantic Ocean, with particular emphasis on the Georges Bank ecosystem (see Fig.…”

“…Stock separation derived from stable isotope chemistry is based upon the metabolically inert nature of otoliths (Campana & Neilson 1985), and the assumption that the calcium carbonate and isotopic composition of otoliths is mainly derived from the water in which the fish reside, as modified by ambient temperature (Campana et al 1995).…”

Analyzing stable isotopes deposited in fish otoliths can provide insights into the environmental variation that individual fish experience throughout their life history which, in turn, can indicate their home range, movements, and underlying stock structure. We investigated the use of stable δ 13 C and δ 18 O isotopes in haddock Melanogrammus aeglefinus otoliths as indicators of environmental variation and stock structure in the northwest Atlantic Ocean. Samples were collected between 1995 and 1998 from individual spawning components on Georges Bank, the Gulf of Maine, and along the Scotian Shelf. Samples from 1 yr-and 4 yr-old haddock were analyzed from an integrated and chronological life history perspective, respectively. Annual, seasonal, and ontogenetic variation in otolith isotopes indicated that haddock undergo shifts in distribution throughout their life history, possibly as a means of compensating for variable environmental conditions; this underlines the difficulty of temperature reconstructions from mobile organisms with optimal temperature ranges.

“…Otolith chemical composition represents a natural tag or fingerprint that may provide information on natal origin and geographic association (Edmonds et al, 1989;Kalish, 1990 a;Secor et al, 1991;Thresher et al, 1994, Thresher, 1999Proctor et al, 1995;Campana et al, 1994;Campana et al, 1995;Campana, 1999). The technique relies on the assumption that certain elements present in the otoliths are related to their physical and chemical environment, and that resorption or alteration of these elements during ontogeny is minimal (Campana, 1999;Campana et al, 2000).…”

SUMMARY: Striped weakfish (Cynoscion guatucupa) and whitemouth croaker (Micropogonias furnieri) are important commercial and recreational species found in abundance along the South American Atlantic coast. In recent years otolith chemical composition has been used as a tool for identifying fish stocks for several species. The chemical composition of C. guatucupa and M. furnieri otoliths was determined by inductively coupled plasma-optical emission spectrometry (ICP-OES) in samples from coastal sites (Partido de La Costa, Mar del Plata and San Blás Bay). Significant differences in the ratios of Mg/Ca, Mn/Ca and Sr/Ca for C. guatucupa otoliths and Cd/Ca, Cu/Ca, Mg/Ca, Sr/Ca and Zn/Ca for M. furnieri otoliths suggest the existence of two different fish stocks, one originating in the north (including Samborombón Bay and Partido de La Costa fisheries) and another originating in the south (including "El Rincón" and San Blás fisheries). These results agree with previous studies on the same species using different methodologies. These stocks may be separated by an oceanographic barrier, the "Frente El Rincón". Otolith chemical composition has not been previously used in South America for identifying fish stocks and may be a simple, quick and useful tool for the sustainable exploitation and management of commercial species. -La pescadilla de red (Cynoscion guatucupa) y la corvina rubia (Micropogonias furnieri) son especies de importancia comercial y recracional abundantes a lo largo de la costa atlántica sudamericana. En recientes años, la composición química del otolito es utilizada como una herramienta para la identificación de stocks pesqueros. La composición química de los otolitos de C. guatucupa y M. furnieri se determino por espectrómetro de emisión atómica (ICP-OES) en muestras provenientes de localidades costeras (Partido de La Costa, Mar del Plata y Bahía San Blás). Se hallaron diferencias significativas en las relaciones Mg/Ca, Mn/Ca y Sr/Ca para C. guatucupa y en Cd/Ca, Cu/Ca, Mg/Ca, Sr/Ca y Zn/Ca para M. furnieri, lo que sugiere la existencia de dos diferentes stocks pesqueros, uno originado en el norte (que incluye las pesquerías de Bahía Samborombón y del Partido de La Costa) y otro stock, originado en el sur (que incluye las pesquerías de "El Rincón" y Bahía Blás). Estos resultados coinciden con los hallados en estudios previos utilizando diferentes metodologías. Estos stocks pueden estar separados por un barrera oceanografía el "Frente El Rincón". La composición química del otolito se utilizo por primera vez en Sudamerica para la identificación de stocks pesqueros, siendo un método fácil, rápido y una herramienta útil para el manejo y explotación sustentable de especies comerciales.
