Marine animal attacks and bites are rarely encountered in Turkey. The invasive alien silver-cheeked toadfish, Lagocephalus sceleratus (Gmelin, 1789), is continuously growing in population and hence becoming increasingly tempted closer ashore especially during the summer months. Infamous with its highly toxic flesh, the species is also capable of inflicting severe bites with its quite strong beak-like teeth. We present the first case of a traumatic amputation caused by L. sceleratus bite in a child who eventually lost the distal part of her finger, in an incident occurred at the northern Levant shore of Turkey.

Key words: Lagocephalus sceleratus, trauma, fish bite, Mediterranean Sea

First record of a coregonid fish species, Coregenus albula (Linnaeus, 1758) (Salmoniformes: Salmonidae) in Aktaş Lake shared between Turkey and Georgia

The genus Coregenus (Salmoniformes: Salmonidae) was recently considered not to be represented in Turkey. European cisco or vendace, Coregonus albula (Linnaeus, 1758) was reported for the first time for Turkey in this article with fifteen samples in Aktaş Lake, Ardahan. This species should be added to the checklist of Turkish fish fauna. Turkish name is proposed as “Akbalık” for this species.

A female specimen of smalltooth sandtiger shark, Odontaspis ferox (Risso, 1810), was caught on April 24, 2018, near Yeni Erenköy, Northern Cyprus at 41 m in depth, by a local commercial fisher. The photos and necessary measurements of the specimen were taken immediately before being sold to a local fish restaurant in Cyprus. This catch is the largest reported O. ferox catch around Cyprus, with a total length of 430 cm.

Keywords: Smalltooth sandtiger shark, Odontaspis ferox, Lamniformes, elasmobranch, by-catch.

Dietary propolis supplementation on growth and body composition of the African catfish Clarias gariepinus (Burchell, 1822)

Dietary propolis supplementation on growth and body composition of the African catfish Clarias gariepinus (Burchell, 1822)

A preliminary study was conducted to evaluate the effect of dietary propolis extract supplementation on African catfish, Clarias gariepinus growth performance, survival rate and body composition. The African catfish (mean body weight 0.45±0.05 g) were fed with experimental diets prepared by using propolis extract supplementation (0, 5 and 10 g kg-1) for 90 days. The weight gain (12.93±0.48 g), FCR (1.39±0.05) and PER (1.44±0.05) were observed higher in catfish fed with 5 g kg-1 propolis extract than fed with 10 g kg-1 propolis extract significantly (P<0.05) but no statistical difference was found with the control group fish (P>0.05). Whole-body crude protein was significantly higher in catfish fed with 5 g kg-1 propolis extract, than in those fed with control and 10 g kg-1 propolis extract (P<0.05). Based on the results of the present study, it is suggested that feeding fish with 5 g kg-1 of propolis extracts for 90 days has no adverse effect on survival and enhanced the better weight gain and protein in the composition of the African catfish.

Head and plastron scalation patterns of the green turtle, Chelonia mydas, hatchlings in natural and relocated nests on Samandağ Beach

An effective protection and management plan for endangered species such as sea turtles is important to secure the existence of their future generations. Positive and negative effects of nest relocation, a conservation strategy, on the morphology and ecology of sea turtles have been previously discussed. However, the effect of this strategy on the plastron scute and head scalation pattern is unknown. Therefore, this study aims to provide further information on plastron scutes and head scalation patterns of the green turtle, Chelonia mydas, hatchlings in relocated and natural nests on Samandağ Beach, Turkey. A total of 195 hatchlings from two nest types were examined during the 2018 nesting season. Significant differences were determined in plastral scutes, while no differences were observed in head scalation between natural and relocated nests. These differences may be related to the nest location in the vertical position because the distance of natural nests to vegetation is significantly less than that of relocated nests (t=-3.612, P=0.004). Considering that the morphology of the green turtle hatchlings (e.g., normal modal scalation) influences their survival, in situ conservation of nests can help us to ensure that healthy individuals will be recruited to the sea turtle population.

This paper presents the results of two vessel surveys in 2017 (spring and summer) in order to estimate cetacean abundance and distribution in Romanian Black Sea waters following distance sampling methods. Eight transects, from east to west, perpendicular on the shore line with a total length of 211.95 km, were designed and executed in sea conditions ≤ Beaufort 4 in an area of 1063 km2with coverage of 39.6%. In total there were 275 sightings of bottlenose dolphin (Tursiops truncatus ponticus), common dolphin (Delphinus delphis ponticus) and harbour porpoise (Phocoena phocoena relicta) recorded. Both European Union (EU) Marine Strategy Framework Directive and Habitats Directive require Member States to monitor and maintain at favourable conservation status those species identified to be in need of protection, including all cetaceans. This study provides the baseline data on the Black Sea cetaceans in Romanian waters.
