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 ... -
Current status of economically important diadromous fish species of Turkey; European eel, Black Sea trout and sturgeon species
(2020)Turkey has a rich variety of fish species in the rivers with a total length of 177,714 km in Turkey. Freshwater fish live in rivers, streams, creeks, dam lakes, natural lakes, wetland areas, etc.The life of migratory fish ... -
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 ... -
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 ... -
Gökkuşağı Alabalığının (Oncorhynchus mykiss) Sperm Kalitesinde Bilgisayarlı Otomatik Sperm Analiz Sisteminde (CASA) Leja ve Makler Lamlarının Performansının Karşılaştırılması
(2020)Bu çalışmada gökkuşağı alabalığının (Oncorhynchus mykiss) spermine ait motilite ve motiliteye ait kinematik parametrelerin Bilgisayarlı Otomatik Sperm Analiz Sistemi (CASA) ile incelenmesinde farklı lamların kullanılmasının ... -
Microplastic consumption and physiological response in Acartia clausi and Centropages typicus: Possible roles of feeding mechanisms
Multi-day experiments were carried out with two Marmara Sea calanoid copepod species: Acartiaclausi and Centropages typicus, to assess the possible role of the type of feeding on the consumptionof microplastics and its ... -
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 ... -
Revisiting safe biological limits in fisheries
The appropriateness of three official fisheries management reference points used in the north-east Atlantic was investigated: (i) the smallest stock size that is still within safe biological limits (SSBpa), (ii) the maximum ... -
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 ... -
