“…Somewhat puzzling, we observed synchrony in White Crappie recruitment when all Osage River basin reservoirs were included, but when a reduced set of reservoirs with a longer time series were compared regional synchrony was not indicated. Obviously, recruitment is influenced by numerous factors, and in some cases localized factors may have been more important in determining recruitment than regional patterns (Cohen et al 1991;Garvey et al 2000), and the relative strength of regional versus local factors may vary temporally.…”

“…Recruitment patterns within or among species may be similar or dissimilar among reservoirs within a region depending on the relative influence of regional-scale versus local-scale processes (Cohen et al 1991;Garvey et al 2000). Regional synchrony in recruitment within or among species has been well documented in marine environments (Cohen et al 1991;Myers et al 1997;Stenseth et al 2002;Noakes and Beamish 2009), rivers (Grenouillet et al 2001;Cattanéo et al 2003;Zorn and Nuhfer 2007;Copeland and Meyer 2011), and in some freshwater lentic systems (Koonce et al 1977;Schupp 2002;Phelps et al 2008) and has been primarily associated with regional climatic phenomena (i.e., Moran effect; Moran 1953;Hudson and Cattadori 1999).…”

Largemouth Bass Micropterus salmoides, Spotted Bass M. punctulatus, White Crappie Pomoxis annularis, and Black Crappie P. nigromaculatus are popular components of many large reservoir sport fisheries, and a better understanding of these populations and their dynamics would improve our management capabilities. We used long‐term datasets (13–37 years) collected from 15 Missouri reservoirs to assess temporal trends and synchrony in sport fish recruitment by using catch per unit effort of age‐1 (CPUE1) black bass Micropterus spp. during spring electrofishing (N/h) and CPUE1 of crappies Pomoxis spp. during fall trap‐netting (N/net‐night) as our index of recruitment. Although CPUE1 exhibited high interannual variation within a reservoir, time series analysis revealed only two significant trends for each of the black bass species, with all trends indicating increasing recruitment. White Crappie CPUE1 showed abrupt declines in all four reservoirs in the Osage River basin, with these declines occurring in different years in each reservoir. White Crappie CPUE1 in one northern reservoir and Black Crappie CPUE1 in all reservoirs appeared to be increasing over time. Within a species, some regional synchrony in CPUE1 occurred for Largemouth Bass, White Crappie, and Black Crappie but not for Spotted Bass. However, synchrony within a species was not universal and in some cases did not exist even among arms within large reservoirs. With few exceptions, there was little evidence for synchronous recruitment among species; those that occurred were among congeners. The lack of synchrony among black bass and crappie recruitment suggests that management practices designed to improve recruitment of one species may not enhance the recruitment of another species.

“…The existence, scale, and interspecies relationships of repeated patterns may yield valuable insight into the nature of the processes driving recruitment variability (Koslow, 1984;Koslow et al, 1987;Cohen et al, 1991;Myers et al, 1997;Hsieh et al, 2005;Mueter et al, 2007). Furthermore, multispecies patterns may provide basic information required to devise effective multispecies and ecosystem fishery management strategies (Ludwig et al, 1993;Christensen, 1996).…”

Contrasting multispecies patterns in larval fish production trace inter-annual variability in oceanographic conditions over the N.E. Aegean Sea continental shelf (Eastern Mediterranean)

The response of larval fish communities of the northeastern Aegean Sea (NEA) to interannual environmental changes is analyzed using data from four ichthyoplankton surveys covering the NEA continental shelf during June 1993June , 1994June , 1995June , and 1996. Waters were significantly cooler, less saline and richer in zooplankton in 1993 and 1996 ('cold' years) than in 1994 and 1995 ('warm' years). A comparison of monthly SST series (1993)(1994)(1995)(1996)(1997) between the NEA, the Marmara Sea, and the Western Black Sea revealed high correlations and similar trend components among these areas implying that oceanographic conditions over the NEA (and observed inter-annual differences) were most likely dominated by the properties and relative amount of Black Sea water inflow in the NEA. The relative composition of the larval fish community was significantly related to the 'cold/warm' regime and larval diversity was higher during the warm years. Larvae of the small-sized pelagic species, such as anchovy (Engraulis encrasicolus), and most mesopelagic fishes were relatively more abundant during the cold, zooplankton-rich years. Larvae of the middlesized pelagics (Sardinella aurita, Scomber japonicus, Trachurus mediterraneaus, Auxis rochei) and certain benthopelagic species exhibited an opposite trend, i.e., they were more abundant during the warm years or absent during the cold years. Most of these species are known to be typical summer spawners (e.g., Serranus cabrilla, Lisa saliens, Trachinus draco, and Symphurus nigrescens). Co-variation in larval fish production might be indicative of similar responses among species to changing physical and/or trophic regimes.

“…The recruitment is thus based on the spawning temperature and modification in the adult stock distribution (Lluch-Belda et al, 1992a;Alvarado-Castillo et al, 1994). The statistical evidence observed in α t during autumn, winter, and spring in Bahía Magdalena, and Isla Cedros can be related to environmental variability of SST (temporal and spatial) on a local scale (Cohen et al, 1991). The changes in upwelling are principally seasonal, and the pattern is strong upwelling during winter and spring, and weak upwelling during summer and fall (Martínez et al, 2000).…”

SUMMARY: The density-independent mortality, considered in the stock-recruitment model of Ricker, was related to the interannual variability of the sea surface temperature (SST) during 1981 to 1993 in Bahía Magdalena, Baja California Sur and Isla Cedros, Baja California, Mexico. From the stock-recruitment curve fitted to the observed data the variation in the density-independent mortality was estimated, maintaining fixed the value of the density-dependent coefficient. The density-independent parameters estimated in this way were related to the SST by using a functional relationship that considers six principal components. This function permitted identification of the changes of the density-independent mortality and its relation to the recruitment of the Pacific sardine Sardinops caeruleus. We determined density-independent mortality greater than 3.38 as years with recruitment greater than 25,000 t, and density-independent mortality less than 3.38 as years with recruitment less than 15,000 t. The seasons of greatest influence on the density-independent mortality in relation to the SST were autumn, winter and spring in both regions (Bahía Magdalena and Isla Cedros). In these seasons when the SST > 19.3°C (warmer waters) the variations in recruitment of Pacific sardine were observed.Key words: sea surface temperature, recruitment, density-independent mortality, Pacific sardine. RESUMEN: RELACIÓN ENTRE EL RECLUTAMIENTO, LA TEMPERATURA SUPERFICIAL DEL MAR Y LA MORTALIDAD DENSO INDE-PENDIENTE DE LA SARDINA DEL PACÍFICO (SARDINOPS CAERULEUS)DE LA COSTA SUROESTE DE LA PENÍNSULA DE BAJA CALIFOR-NIA, MÉXICO. -La mortalidad denso independiente considerada en el modelo de stock reclutamiento de Ricker fue relacionada con la variabilidad interanual de la temperatura superficial del mar (TSM), durante el periodo de 1981 a 1993 en Bahía Magdalena, Baja California Sur e Isla Cedros, Baja California, México. Ajustando la curva stock reclutamiento a los datos observados, se estimó la variación de la mortalidad denso independiente, manteniendo constante el valor del coeficiente de mortalidad denso dependiente. Los parámetros de denso independencia estimados de ésta forma, fueron relacionados con la TSM usando una relación funcional que considera seis componentes principales. Esta función permitió identificar los cambios en la mortalidad denso independiente y su relación con el reclutamiento de la sardina del pacífico Sardinops caeruleus. Se determinó una mortalidad denso independiente > 3.38 como años con reclutamiento > 25,000 t, y mortalidad denso independiente < 3.38 como años con reclutamiento < 15,000 t. Las estaciones de mayor influencia sobre la mortalidad denso independiente en relación a la TSM fueron: otoño, invierno y primavera en ambas regiones (Bahía Magdalena e Isla Cedros). En estas estaciones fueron observadas las variaciones en reclutamiento de la sardina del pacífico cuando la TSM > 19.3°C
