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 ... -

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 ... -
Effects of leptin on the epithelial cell proliferation from the small intestine and nitric oxide (NO) production in rats
Leptin encoded by the obese gene exhibits various functions, especially in the regulation of food intake and energy expenditure. The aims of this study are to investigate some specific intestinal roles of leptin, i.e. the ... -
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 ... -
Estimating fisheries reference points from catch and resilience
This study presents a Monte Carlo method (CMSY) for estimating fisheries reference points from catch, resilience and qualitative stock status information on data-limited stocks. It also presents a Bayesian state-space ... -
EVALUATION OF ATLANTIC BLUEFIN TUNA OTOLITH AGEING PROTOCOLS
(2020)An otolith ageing bias for juvenile Atlantic bluefin tuna was detected at the 2017 population assessment. Consequently, revised reading criteria were proposed to reduce this ageing bias. To evaluate standardized and revised ... -
