A critique of the balanced harvesting approach to fishing
The approach to fisheries termed "balanced harvesting" (BH) calls for fishing across the widest possible range of species, stocks, and sizes in an ecosystem, in proportion to their natural productivity, so that the relative ... -
Effect of Long-Term Feeding with Dried Microalgae Added Microdiets on Growth and Fatty Acid Composition of Gilthead Sea Bream (Sparusaurata L., 1758)
The aim of the present study was to investigate the effects of replacing fish oil by different microalgae products on the growth performance and fatty acid composition of gilthead sea bream (0.02 +/- 0.00 g) during 90 days ... -
Effects of Different Commercial Feeds and Enrichments on Biochemical Composition and Fatty Acid Profile of Rotifer (Brachionus Plicatilis, Muller 1786) and Artemia Franciscana
The objective of the present study was to determine the effects of several commercial rotifer feeds and enrichments on growth, biochemical and fatty acid composition of L-type rotifer and Artemia franciscana nauplii. In ... -
Ichthyoplankton dynamics in a highly urbanized estuary
Spatio-temporal distribution and composition of ichthyoplankton assemblages were studied in the Golden Horn estuary (Istanbul) over a 10-month period. Environmental parameters were considered to determine the environmental ... -
Influence of the extreme conditions on the water quality and material exchange flux in the strait of Istanbul
This study focuses on the influence of extreme hydrological events on the water quality of the Strait of Istanbul (Bosphorus), a stratified waterway, polluted by sewage outfalls and non-point sources. Monthly collected ... -
On the pile-up effect and priors for L-inf and M/K: response to a comment by Hordyk et al. on "A new approach for estimating stock status from length frequency data" Reply
We thank Hordyk et al. (2019) for pointing out a typographical error in one of our equations, which has meanwhile been fixed in the online version of Froese et al. (2018) and addressed in a corrigendum for the printed ... -
Reply to Andersen et al. (2016) "Assumptions behind size-based ecosystem models are realistic"
In a recent publication (Froese et al., ICES Journal of Marine Science; 73: 1640-1650), we presented a critique of the balanced harvesting (BH) approach to fishing. A short section dealt with the size-spectrum models used ... -
Seasonal variations of epipelic algal community in relation to environmental factors in the Istanbul Strait (the Bosphorus), Turkey
This study was implemented to investigate the species composition, abundance, seasonal variations and diversity of epipelic algae, to determine environmental variables affecting them and to reveal the accumulation of total ... -
Spawning Frequency of Trachurus mediterraneus (Carangidae) in The Sea of Marmara
In this study the spawning frequency of Trachurus mediterraneus was estimated for the first time in the Mediterranean basin. The presence of the late-migratory nucleus stage oocytes and post ovulatory follicles (POFs) in ...
