State of Black scorpionfish (Scorpaena porcus linnaeus, 1758) inhabited coastal area of Sevastopol region (Black Sea) in 1998–2008

İskorpit Scorpaena porcus stoklarının durumu konusunda 1998-2008 dönemine ait veriler incelendiğinde, yaş kompozisyonunda 1998’e göre 2008 yılında daha geniş aralık olduğu belirlendi. Balıkların cinsiyetlerine göre farklı yaş gruplarında son yıllarda (2007-2008) iyileşme oldu, ama 1998’den 2005’e kadar özellikle dişi bireylerde, daha yaşlı örnekler baskındır. Bu dönemde kondisyon faktörü artmakla birlikte, iskorpit bireylerde düşük büyüme ve kilo kaybı faktörlerinin karmaşık olumsuz etkisi belirlenmiştir. Bu tür etkiler çalışma alanında çevre koşulları, kirlilik ve sıcaklık yükselmesi gibi bazı değişkenlerin sonucu olabilir.

Siyah İskorbitBalığı (Scorpaena porcus linnaeus, 1758) stoklarının Sivastopol Bölgesi (Karadeniz) kıyısal alanında 1998-2008 yılları arasında durumu

Data about scorpion fish population state during 1998-2008 were presented. It was determined that age composition of Scorpaena porcus from 1998 to 2008 has been widened. The amount of females and males of different age groups in last years (2007-2008) was optimal, but from 1998 to 2005 females, especially older specimens, dominated. Condition factor increased. However, scorpion fish bodies smaller growth and weight decrease were noticed, that demonstrates negative influence of complex of factors. Such effects may be some result of changing environmental conditions in the study area such as pollution and temperature rise.
