Some Biological Parameters of Sprat Sprattus Sprattus Phalericus (risso1826) in the Turkish Black Sea Coast
Some biological parameters of the sprat, Sprattus sprattus phalericus, collected from Turkish Black Sea coast between 2008 and 2009 were investigated. Sprat is an important food resource for many top predators. In present work, length frequency distribution, relationship between length and weight, sex ratio and condition factor of sprat have been studied.
متن کاملDepth-dependent nutritional condition of sprat Sprattus sprattus larvae in the central Bornholm Basin, Baltic Sea
Bimodal depth distribution patterns observed for sprat Sprattus sprattus larvae in previous field studies conducted in the deep basins of the Baltic Sea have led researchers to hypothesise that larval sprat condition was depth-dependent. We examined this hypothesis by measuring morphological, biochemical and otolith-based proxies for nutritional condition in sprat larvae collected in discrete 5...
متن کاملThe influence of temperature on the development of Baltic Sea sprat (Sprattus sprattus) eggs and yolk sac larvae
In spring 2004 and 2005 we performed two sets of experiments with Baltic sprat (Sprattus sprattus balticus Schneider) eggs and larvae from the Bornholm Basin simulating ten different temperature scenarios. The goal of the present study was to analyse and parameterise temperature effects on the duration of developmental stages, on the timing of important ontogenetic transitions, growth during th...
متن کاملSurfacing behavior and gas release of the physostome sprat (Sprattus sprattus) in ice-free and ice-covered waters
Upward-facing echosounders that provided continuous, long-term measurements were applied to address the surfacing behavior and gas release of the physostome sprat (Sprattus sprattus) throughout an entire winter in a 150-m-deep Norwegian fjord. During ice-free conditions, the sprat surfaced and released gas bubbles at night with an estimated surfacing rate of 3.5 times per fish day-1. The vertic...
متن کاملSensory and Chemical Properties of Baltic Sprat (Sprattus sprattus balticus) and Baltic Herring (Clupea harengus membras) in Different Catching Seasons
Abstract. Baltic sprat (Sprattus sprattus balticus) and Baltic herring (Clupea harengus membras L) are two of the most caught fish species among the Estonian seacoast fishermen, and therefore it is important to understand catching season effects on sprat and herring sensory and nutritional quality. The aim of this study was to measure and compare sensory and chemical variability of Baltic sprat...
