Bycatch in the commercial beam trawl fishery for Rapa Whelk in the Black Sea
(Natl Centre Marine Research, 2018)The current study was aimed to investigate the bycatch in commercial beam trawls used in the rapa whelk (Rapana venosa) fishery during September 1, 2015, and April 30, 2016. Four commercial boats using beam trawls were ... -
Biomonitoring of metal(oid)s in mining-affected Borcka Dam Lake coupled with public health outcomes
(Taylor & Francis Inc, 2018)Due to increased anthropogenic activities, the aquatic environment is exposed to pollutants much more than ever. These pollutants go into the food chain and can pose a health risk to human. Correlatively, Borcka Dam Lake, ... -
Effects of square-mesh codend on the benthic by-catch for the beam trawl fisheries of veined rapa whelk, rapana venosa
(Wydawnictwo Akad Rolniczej W Szczecinie, 2018)Background. the beam trawl fisheries of veined rapa whelk, Rapana venosa (Valenciennes, 1846), cause small benthic organisms to be captured and also damage the other species living on the seafloor. To solve this problem, ... -
A preliminary study on whiting (Merlangius merlangus) behaviour to bottom-set pot in the Black Sea
(Parlar Scientific Publications (P S P), 2018)Due to overfishing and decreasing in fish stocks, interactions between dolphins and deep gill nets have increased rapidly in recent years for the Black Sea. Dolphin-inflicted damage to fishing gear and catch losses have ... -
The water quality of streams flowing İnto South Eastern Black Sea coasts in terms of physico-chemical properties

A novel grid-net design to eliminate bycatch in beam trawl fishing for the veined rapa whelk in the south-eastern Black Sea
(Natl Centre Marine Research, 2018)Beam trawl fisheries in the Black Sea target the veined rapa whelk (Rapana venosa) while other species of fish and crabs are returned to the sea dead or alive. Smaller bivalves and crabs are also packed with the catch ... -
Synthesis, molecular docking and biological evaluation of some benzimidazole derivatives as potent pancreatic lipase inhibitors
(Academic Press Inc Elsevier Science, 2018)In this study, a new series of benzimidazole and bisbenzimidazole derivatives were prepared via the reaction of iminoester hydrochlorides and o-phenylenediamines and then screened for their lipase inhibition properties. ... -
Dye of waste tea extract with mordant-varnish and the effect of color changes on wood
(Health & Environment Assoc, 2018)This study aimed to develop natural dyes for wood material that are harmless to humans and the environment. For this purpose, a tea stain and polyurethane single- and double-component water based varnish were applied by ... -
Gobiid fishes of the coastal zone of the Northeastern Aegean Sea
(Springer Heidelberg, 2018)In this study gobiid fish species were investigated at 31 stations from the northeastern Aegean Sea. Different habitat types between 0 and 50 m depth were studied by scuba diving with newly modified underwater visual census ... -
Synthesis and characterisation of some new hybrid molecules containing thiophene, triazole and coumarin rings under microwave conditions
(Sage Publications Ltd, 2018)In this work, a new series of N'-{[4-amino-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetyl}-2-oxo-2H-1-benzopyran-3-carbohydrazides (thiophene-triazole-coumarin hybrid molecules) was synthesised from the ... -
