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 ... -

Comparison of the effects of different sa concentrations on senescence in excised rocket (Eruca sativa L.) cotyledons
Senescence, accepted as the last phase of growth in plants, is characterized by a series of degenerative events that decrease the metabolic activity and eventually cause the death of cells, tissues and organs. In the present ... -
Comparison of TPH Contamination in Coastal Surface of North Aegean and Marmara Seas: Prince Islands and Gokceada
(2019)In this study. throughout 2017, TPH values were determined in surface water samples taken seasonally from 15 different stations around Gokceada and monthly from the 4 resided islands (from one spot for each) of Princes' ... -
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 ... -
Effect of salicylic acid on pigment, protein content and peroxidase activity in excised sunflower cotyledons
(2009)Enviromental stress gives rise to the activation of adaptation and defence responses in plants. It is known that the role of salicylic acid (SA) is quite important in this mechanism. In this study its effect was investigated ... -
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 ... -
Ent-kaurene Diterpenoids from Sideritis lycia with Antiviral and Cytotoxic Activities
(2020)The genus Sideritis (Lamiaceae) is represented by 45 species (54 taxa) in Anatolia with high endemism ratio (74%), and Turkey is one of the gene centers of the genus along with Spain. Acetone extract of the aerial parts ... -

Palavan-Unsal, N., Cag, S. and Cetin, E. 2002. Growth responses of excised radish cotyledons to meta-topolin. Can. J. Plant Sci. 82: 191-194. Meta-topolin (mT) has been established as an active aromatic cytokinin by Strnad ... -
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 ... -
