“…Experiments that have detected a positive effect on Sr with temperature reared fish at high temperatures (i.e., 20°C and above) Fuiman 1993, 1995;Bath et al 2000), whereas those that detected negative effects reared fish at low temperatures (i.e., 17°C and below) (Townsend et al 1992(Townsend et al , 1995. However, there are experiments that do not conform to these trends, such as Kalish (1989), who detected a slight increase in Sr:Ca with temperature using treatments of 13, 16, 19, and 22°C.…”

Abstract:The concentrations of elements and isotopes in fish otoliths may provide a method of reconstructing movements of fish by differentiating between water bodies of different temperatures and salinities. However, before otoliths can be used to reconstruct environmental histories of fish, it is necessary to assess the effects of seawater temperature and salinity on otolith microchemistry. Using controlled laboratory experiments, juvenile black bream, Acanthopagrus butcheri (family Sparidae), were reared for 50 days in aquaria of varying temperatures and salinities using three experimental designs: temperature × salinity, temperature only, and salinity only. Temperature and salinity interacted to significantly affect the elemental concentration ratios of Sr:Ca and Ba:Ca and the concentrations of isotopes δ 13 C and δ 18 O in otoliths. The single-factor experiments showed that temperature significantly affected the concentration ratios of Sr:Ca and Ba:Ca and the concentrations of δ 13 C and δ 18 O in otoliths, whereas salinity alone did not affect the concentration ratios of any elements but did affect both isotopes. The concentration ratios of Mg:Ca and Mn:Ca varied considerably among fish within the same treatment level and showed little or no effects due to temperature and (or) salinity. The significant interactive effects of temperature and salinity on otolith microchemistry highlight the need for a multifactorial approach to testing hypotheses regarding the environmental histories of fish.Résumé : Les concentrations d'éléments et d'isotopes dans les otolithes de poissons peuvent fournir une méthode pour retracer les déplacements des poissons en discriminant entre des masses d'eau de températures et de salinités différen-tes. Cependant, avant que les otolithes ne puissent servir à récapituler l'histoire environnementale des poissons, il est nécessaire de déterminer les effets de la température et de la salinité de l'eau de mer sur la microchimie des otolithes. Dans des expériences de laboratoire contrôlées, nous avons élevé des jeunes « brèmes noires », Acanthopagrus butcheri (famille des Sparidae), durant 50 jours dans des aquariums de salinités et de températures différentes selon trois plans d'expérience: température × salinité, température seule et salinité seule. La température et la salinité interagissent pour affecter de façon significative les rapports des concentrations d'éléments Sr:Ca et Ba:Ca,, ainsi que des isotopes δ 13 C et δ 18 O dans les otolithes. Les expériences qui tiennent compte des facteurs séparément indiquent que la température affecte de façon significative les rapports des concentrations de Sr:Ca, Ba:Ca, δ 13 C et δ 18 O dans les otolithes, alors que la salinité seule n'affecte pas les rapports des éléments, mais seulement les deux isotopes. Les rapports des concentrations de Mg:Ca varient considérablement chez les poissons soumis à un même traitement et ne sont que peu affectés par la température et/ou par la salinité ou alors ne sont pas affectés du tout. Les effets significati...

“…These types of targeted assays have been used to reconstruct migration histories (Secor et al 1995b. Thorrold et al 1997a), identify nursery areas (Thresher et al 1994, Milton et al 1997, and determine Sr:Ca ratios in order to infer temperature history (Radtke et al 1990, Townsend et al 1995. The advantages of an age-structured approach are obvious, particularly since the beam sizes of the current generation of instruments approach the width of a typical daily increment ( Table 3).…”

ABSTRACT:The fish otolith (earstone) has long been known as a timekeeper, but interest in its use as a metabolically inert environmental recorder has accelerated in recent years. In part due to technological advances, applications such as stock identification, determination of rnigralon pathways, reconstruction of temperature and salinity history, age validation, detection of anadromy, use as a natural tag and chemical mass marking have been developed, some of which are difficult or impossible to implement using alternative techniques. Microsamphg and the latest advances in beam-based probes allow many elemental assays to be coupled with daily or annual growth increments, thus providing a detailed chronologcal record of the environment. However, few workers have critically assessed the assumptions upon which the environmental reconstructions are based, or considered the possibility that elemental incorporation into the otolith may proceed differently than that into other calcified structures. This paper reviews current applications and their assumptions and suggests future directions. Particular attention is given to the premises that the elemental and isotopic composition of the otolith reflects that of the environment, and the effect of physiological filters on the resulting composition. The roles of temperature, elemental uptake into the fish and the process of otolith crystahzation are also assessed. Drawing upon recent advances i n geochemistry and paleoclirnate research as points of contrast, it appears that not all applications of otolith chemistry are firmly based, although others are destined to become powerful and perhaps routine tools for the mainstream fish biologst.

“…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
