The Mediterranean Large Elasmobranchs Monitoring (MEDLEM) database contains over 3000 records (more than 4000 individuals) of large elasmobranch species from 20 different countries around the and Black seas, observed 1666 to 2017. main included in archive are devil fish (1 813 individuals), basking shark (939 blue (585 great white (337 individuals).In last decades other such as shortfin mako (166 spiny butterfly ray (138) thresher (174 were reported with an increasing frequency. This was...
The Sea of Marmara (SoM), without doubt, is one the most disturbed marine ecosystems Mediterranean basin. As a semi-enclosed and recognized eutrophic basin, it has unique natural characteristic by permanent stratification at ~25 m depth. SoM ecosystem under threat multiple stressors from excessive nutrient enrichment, overfishing, invasive species, habitat loss to climate change. Within this study, an assessment on structure functioning its changes over time have been achieved. Hence, we...
This study presents the catch composition and biodiversity of Mersin Bay, northeastern Mediterranean, which is an important fishing ground for demersal trawls. A total 182 hauls were performed on board a commercial trawler grounds between 15 September 2009 April 2013. The monthly changes in species analyzed by conducting cluster analysis based per unit effort (CPUE), nonmetric multidimensional scaling (nMDS), correlation vectors, used to evaluate discrete groups. Shannon-Wiener index (H'),...
Knowing post-release survival rates of fish escaping or being thrown back into the sea as discards is important for effective stock assessment.The aim this study was to estimate short-term discard two most abundant by-catch skate species (thornback skate: Raja clavata and brown miraletus) in bottom trawl fisheries Antalya Bay determine factors affecting skates.For thornback mean health score, percentage with a score 2 dead at time zero were 2.3, 91% 2%, respectively.For skate, these values...
Length–weight relationships (LWRs) are presented for eight teleost and two elasmobranch fish species representing ten families that were captured in deep water (from 400 to 1000 m, except the stingray Dipturus centrura) Antalya Bay. This study represents first LWR references of these species.
Groupers are important fishes for the coastal ecosystems because of having a key role in functioning marine food webs. Their populations increasingly affected by overfishing, habitat loss, and global warming. Since reliable scientific background is lacking, their conservation based on precautionary approaches, applicability, effectiveness which long questioned. Changes Turkey's grouper fishery legislation constitute an excellent example how approach could not gain acceptance among...
Poor selectivity and high discard rate of hand-woven slack knotted codend is a serious problem for north eastern Mediterranean demersal fish stocks.This study investigates the effect circumference on bottom trawl red mullet (Mullus barbatus), bogue (Boops boops), goldband goatfish (Upeneus moluccensis), Randall's threadfin bream (Nemipterus randalli) picarel (Spicara smaris).A total 18 valid hauls were conducted using covered method between 08 October 26 December 2012 in Mersin Bay.Results...
Globally, all marine ecosystems are under pressure by anthropogenic stressors. However, semi-enclosed seas at a greater risk of degradation due to their limited connectivity open seas. This leads accumulation pollutants and abrupt regime shifts triggered unsustainable exploitation living resources, as exhibit low degrees redundancy more frequent large-scale episodic events such harmful algal blooms. The Sea Marmara is region that has been subjected various stressors since the 1990s....
Türkiye’de balık avı istatistikleri Türkiye İstatistik Kurumu (TUİK) ve T.C. Tarım Orman Bakanlığı koordinasyonunda periyodik olarak toplanıp, global istatistiklerini toplayıp, ilan eden Birleşmiş Milletler Gıda Örgütüne (FAO) raporlanmaktadır. Av miktarlarının doğruluğu konusunda tartışmalar olsa da, zaman serisi av trendlerinin güvenilir olduğu birçok araştırma ile ortaya konmuştur. Bu yüzden, istatistikleri, stok değerlendirmeleri balıkçılık yönetimi için oldukça değerli bir veri...
Abstract Switching from the traditional 40- or 44-mm diamond mesh codends to 50-mm (D50) 40-mm square (S40) is known improve size selection for commercial species and reduce discarding in Mediterranean demersal trawl fisheries. This change has been recommended General Fisheries Commission European regulations. However, ecosystem-based assessment of improved selectivity still remains a challenge, that aim this study. For purpose, an Ecopath model was developed used initialize dynamic...
