Marmara Denizi'nde Algarna ile Avlanan Triglidae Türlerinin Boy-Ağırlık İlişkisi ve Bolluk Dağılımı

Abstract

Bu çalışmada, Marmara Denizi'nde üç kırlangıç türünün Chelidonichthys lucerna (Linnaeus, 1758), Lepidotrigla cavillone (Lacepède, 1801), Eutrigla gurnardus (Linnaeus, 1758)’un boy-ağırlık ilişkileri, birim av miktarları ve bollukları (CPUE kg/sa, N/sa) mevsimlere, bölgelere ve derinliklere göre belirlenmiştir. Örnekler Ekim 2011- Temmuz 2014 tarihleri arasında algarna av aracı kullanılarak aylık olarak elde edilmiştir. Marmara Denizi altı av sahasına; 1. bölge: Erdek, 2. bölge: Tekirdağ, 3. bölge: Marmara Adası, 4. bölge: Kapıdağ, 5. bölge: Yalova, 6. bölge: Silivri ayrılarak, toplam 229 adet algarna çekimi yapılmıştır. 3 triglidae türü için b değeri 2,66 ile 2,85 arasında değişmiştir. C. lucerna ve L. cavillone negatif allometrik büyüme, E.gurnardus izometrik büyüme göstermiştir. Algarna ile avlanan türlerin toplam birim avı 63,6 kg/sa, kemikli balıkların birim avı 4,7 kg/sa, triglidae familyasına ait balıkların birim avları 0,422 kg/sa (%9) dir. Kırlangıç türleri arasında en yüksek bolluk C. lucerna türünde (0,305 kg/sa - 2,5 N/sa) belirlenmiştir ve onu sırasıyla L. cavillone (0,066 kg/sa-1,9 N/sa) ve E. gurnardus (0,051 kg/sa - 0,96 N/sa) türleri takip etmiştir. Mevsimlere göre en yüksek bolluk C. lucerna ve L. cavillone türleri için yaz döneminde, E. gurnardus için ilkbaharda bulunmuştur. Bölgelere göre en yüksek bolluk C. lucerna için Tekirdağ'da, L. cavillone için Kapıdağ Yarımadası'nda ve E. gurnardus için Marmara Adası av sahasında tespit edilmiştir. Derinliklere göre triglidae türlerinin birim av miktarı değişmiştir. C. lucerna ve L. cavillone'nin 50-100 m derinlik aralığında, E. gurnardus’un 100 m'den daha derinlerde daha bol olduğu tespit edilmiştir.

Length-Weight Relationships and Abundance Distribution of Triglidae Species Caught by Beam-trawl in The Sea of Marmara

Abstract

In this study, length–weight relationships and the catch per unit effort-relative abundance (CPUE kg/h, N/h) of the three-gurnard species Chelidonichthys lucerna (Linnaeus, 1758), Lepidotrigla cavillone (Lacepède, 1801), Eutrigla gurnardus (Linnaeus, 1758) were determined according to season, area and depth in the Sea of Marmara. Samples were obtained by beam trawl monthly between October 2011-July 2014. Total of 229 station were sampled. Totally six fishing area distributed as 1. area: Erdek, 2. area: Tekirdağ, 3. area: Marmara Island, 4. area: Kapıdağ, 5. area: Yalova and 6. area: Silivri. The parameter b for 3 triglidae species ranged from 2.66 to 2.85. The exponent b typically indicated C. lucerna and L. cavillone negative allometric growth, E.gurnardus isometric growth. The relative abundance of all species caught by beam trawl, bony fishes and triglidae species were determined as 63.6 kg/h, 4.7 kg/h and 0.422 kg/h (9%), respectively. The highest abundance (CPUE) in triglidae family was determined as 0.305 kg/h (2.5 N/h) in C. lucerna species and followed by L. cavillone 0.066 kg/h (1.9 N/h and E. gurnardus 0.051 kg/h (0.96 N/h) species. According to the seasons, the highest abundance of C. lucerna and L. cavillone species was found in the summer, spring for E. gurnardus species. According to the region, the highest abundance was found in Tekirdağ for C. lucerna species, Kapıdağ Peninsula for L. cavillone species and Marmara Island for E. gurnardus species. According to the depth, the abundance (CPUE) of the gurnard species has changed. It was found that C. lucerna and L. cavillone were more abundant at depths of 50-100 m, deeper than 100 m for E. gurnardus.
