چکیده

Bu çalışmada Dil Balığı, Solea solea türünün Marmara Denizi’ndeki boy-ağırlık ilişkisi, yaş, büyüme ve ölüm parametreleri üreme biyolojisi ele alınmıştır. Örneklemeler 34 istasyondan Mart 2017 ile Aralık 2018 arasında dip trolü gerçekleştirilmiştir. Boy-ağırlık ilişkisi W=0,0082×TL3.01 olarak hesaplanmıştır. Bireyler 1 5 yaş aralığında dağılım göstermiştir. Von Bertalanffy L∞=34,.56 cm, K=0,48 y-1, and t0=-0,01 y şeklinde İlk eşeysel olgunluk boyu 21.9 cm TL tespit edilmiştir. Eylül’den Nisan’a kadar geniş bir periyodu Doğal oranı (M), toplam (Z), balıkçılık ölümü (F) sömürülme sırasıyla 0,79, 2,4, 1,61 0,67 belirlenmiştir. Biyolojik referans noktaları Fopt=0,395; Flim=0.53 Eopt=0,333 En yüksek ürünün elde edilebileceği en uygun boy (Lopt) 22,3 bulunmuştur. Sonuçlar Balığı’nın Denizi’nde aşırı avcılık etkisinde olduğunu göstermektedir.

Solearhynchus kostylewi (Meyer, 1932) comb. nov. (acanthocephala: Echinorhynchidae), a rare parasite of Solea solea (pisces: soleidae) in the Gemlik Bay, Sea of Marmara.

Paracanthocephaloides kostylewi (Meyer, 1932), a rare parasite of the common sole Solea solea, previously placed in the Arhythmacanthidae, is transfered to the genus Solearhynchus de Buron & Maillard, 1985 of the family Echinorhynchidae as Solearhynchus kostylewi (Meyer, 1932) new comb., because its proboscis is armed by a single type of hooks, the posterior hook in each row is pinlike and with...

Sea-Scale Agent-Based Simulator of Solea solea in the Adriatic Sea

DISPAS is an agent-based simulator for fish stock assessment developed as a decision making support for the sustainable management of fishery. In this work we enlarge the underlying model of DISPAS allowing it to model and simulate a multi-scale scenario. We retain the currently available spatial scale, able to represent a limited average region of the sea, and we introduce a new spatial macro-...

Effects of exposure to petroleum hydrocarbons upon the metabolism of the common sole Solea solea.

On December 12th, 1999, the oil tanker Erika sank off the southern coast of Brittany (France), releasing 20000-30000tons of heavy oil in the open sea. Among the affected coastal habitats were important nurseries for numerous flatfish species and particularly for the common sole, Solea solea. To investigate the potential impact of the spill on this economically significant resource, we employed ...

Fatal Asphyxiation in Two Long-Finned Pilot Whales (Globicephala melas) Caused by Common Soles (Solea solea).

Long-finned pilot whales (Globicephala melas) are rare visitors to the southern North Sea, but recently two individual strandings occurred on the Dutch coast. Both animals shared the same, unusual cause of death: asphyxiation from a common sole (Solea solea) stuck in their nasal cavity. This is a rare cause of death in cetaceans. Whilst asphyxiation has been reported in smaller odontocetes, the...

Effect of exposure to petroleum hydrocarbons upon cardio-respiratory function in the common sole (Solea solea).

The long term consequences of oil exposure upon marine populations are still poorly evaluated. One particular missing piece of information relates to the link between oil exposure, individuals' ability to face environmental contingencies and populations' production and dynamics. In that context, the present paper investigates the impact of oil exposure upon fish cardio-respiratory performance, ...
