The relationships between size (length and width) of the lagenar (asteriscus) utricular (lapillus) otoliths body length for five cyprinid fish species, freshwater bream Abramis brama, white Blicca bjoerkna, Prussian carp Carassius gibelio, brond-snout Chondrostoma regium, rudd Scardinius erythrophthalmus, collected from Lake Ladik November 2009 through October 2010, are presented. right left side measurements were pooled in all cases except asteriscus carp. Nonlinear linear functions...
Asteriscus otolith shapes as well their morphometry and shape contours were investigated in order to identify four allopatric Alburnus species: A. chalcoides (Güldenstädt, 1772) (Ordu), escherichii Steindachner, 1897 (Eskişehir), mossulensis Heckel, 1843 (Tunceli), tarichi 1814) (Van) Turkish inland waters. These compared using the indices (form factor, roundness, circularity, ellipticity, rectangularity aspect ratio), morphological characters [otolith weight (OWE), length (OL), width (OW),...
Otoliths, which can be used for the evaluation of relationships between environment and organisms, are structures consisting calcium carbonate.The aim this study was to realize shape analysis.In addition, it is detect characteristics otolith biometrics in order determine relationship fish size Engraulis encrasicolus L. from Black Marmara Seas.The samples were obtained Seas December 2013 February 2014.The TL (Total length) OL (Otolith length), OB breadth), OW weight) determined using linear...
The zooplankton composition of Lake Ladik, located in Samsun Province northern Turkey, was investigated monthly between November 2009 and October 2010. Some physicochemical parameters such as temperature surface water, pH, dissolved oxygen, salinity, conductivity, total solids were also evaluated. A 29 species identified. These represented by three main groups: Rotifera (59%), Cladocera (24%), Copepoda (17%). maximum minimum numbers found July October, respectively. Bosmina longirostris,...
In this third Collective Article, with fisheries-related data from the Mediterranean Sea, we present historical length distribution of Lophius budegassa in catch commercial trawlers Greek seas; length-weight and length-length relationships five flatfish species (Lepidorhombus boscii, L. whiffiagonis, Platichthys flesus, Pegusa lascaris Solea solea) different coastal areas Turkey (Black Sea Eastern Sea); growth settled Polyprion americanus Deltentosteus quadrimaculatus, Capros aper three...
Feeding habits and prey selection of European perch (Perca fluviatilis) were examined in Lake Ladik between November 2009 October 2010. Stomach contents 308 individuals ranging size from 73 to 275 mm total length analyzed 55.2% empty. The fullness index indicated that feeding intensity this species was the highest summer lowest winter. feeds on fish macroinvertebrates. most important food items Scardinius erythrophthalmus Perca fluviatilis, followed by chironomidae larvae. Diet composition...
The morphology, biometry and shape indices of the left right sagittal otoliths were studied for sharpsnout seabream, Diplodus puntazzo species from Aegean Sea.The shape, sulcus acusticus proximal distal surfaces, anterior posterior regions a total 52 D. analyzed.The morphometric measurements such as weight, length, width, area perimeter recorded each pair seabream.The form factor, roundness, aspect ratio, circularity, rectangularity, ellipticity calculated puntazzo.The otolith width...
This study focuses on the relationships between otolith measurements and total length; shape indices among for three Atherina boyeri populations (Lake Eğirdir, Lake Iznik, Hirfanlı Dam Lake) to determine regional variations of these in Turkey. 356 specimens with 41.0 - 103.6 mm length A. were examined their otoliths extracted measured. Otolith width is strongest indicator although length, width, weight are good indicators fish different populations. The linear relationship was determined...
This study was carried out to determine the intra- and inter- population variations of chub, Squalius cephalus , utricular lagenar otolith shapes sampled from four localities in Black Sea region. Otolith shape indices, including Form Factor (FF), Circularity (C), Roundness (RO), Rectangularity (RE), Aspect Ratio (AR) Ellipticity (E) were used for analyses multivariate analyzes (Canonical Discriminant Analysis) assess interspecies variations. The FF C found statistically significant lapillus,...
In total, 240 tarek, Alburnus tarichi, specimens were caught throughout February 2008 in Lake Van, Turkey, a lake with highly salty-alkaline conditions. Ages, lengths and weights of A. tarichi determined to estimate length–weight relationships age composition. Otolith dimensions also determined. Female : male ratio was 1.47 1. Fork length total weight ranged from 14.3 19.2 cm 45.76 99.63 g, respectively. Maximum observed 6 years. Length–weight calculated for female, combined sexes as, W =...
I In the present study, a comparison of otolith morphology Alburnus tarichi , collected from different localities throughout Van Basin was carried on. A total 351 specimens A.tarichi by trammel nets four (Van, Erçek, Nazik, Aygır) during period April-May 2015 were examined. Fork length and body weight ranged between 9.9-24.6 cm 8.4-176.5 g, respectively. Lagenar otoliths removed discriminating as left right. Otolith ( OL ), breadth OB ) OW collected. Comparisons right-left measurements...
This study was conducted to determine feeding biology and prey selection of pike inhabiting Lake Ladik (Ladik, Samsun).Sampling carried out monthly between November 2009 October 2010.The stomachs 204 individuals were analyzed 32.35% them empty.Feeding intensity varied by seasons length group.Fullness index values the lowest during summer in large sized pike, while highest autumn small specimens.Prey fish dominated diet all groups throughout year whereas on invertebrates limited pikes.For...
In this study, length-weight relationship (LWR) and length-length (LLR) of bluefish, Pomatomus saltatrix were determined. A total 125 specimens sampled from Samsun, the middle Black Sea in 2014 fishing season. Bluefish monthly collected commercial boats October to December 2014. All captured individuals (N=125) measured nearest 0.1 cm for total, fork standard lengths. The weight each fish (W) was recorded 0.01 g. According results analyses, there no statistically significant differences...
This research was conducted to record the fish species inhabiting Lake Ladik and its inlet outlet streams between July 2003 August 2004. Electrofishing equipment, fishing cast net, fisherman's dip nets with different scales were used catch samples. As a result of evaluated samples caught from area, 12 belonging 4 families (Cyprinidae, Balitoridae, Esocidae, Percidae) identified.
ABSTRACT This study describes the length-weight (LWR) and length-length relationships of Capoeta sieboldii from Hirfanli Dam Lake, Turkey. Condition factor (K) was also calculated per fork length class females males. A total 170 individuals collected monthly sampling between March 2004 August 2005. LWRs males were not statistically different with within season. indicated isometric growth in both sexes. The slopes 3.171 for 2.980 All correlations among length, standard highly significant...
In this study, the length-weight and length-length relationships of chub ( Squalius cephalus, L.1758) sampled from a few inland waters middle Black Sea were investigated. A total 218 (Abdal (N=44), Akçay (N=57), Terme (N= 55), Yedikır (N=62)) individuals different localities. All captured measured to nearest 0.1 cm for total, fork standard lengths. The weight each sample (W) was recorded (0.01 g). According results analyses, there no statistically significant differences between sexes in...
A total of 1329 samples were collected from monthly sampling between November 2009 and October 2010 in order to analyze growth features population structure rudd Scardinius erythrophthalmus living Lake Ladik which has eutrophic character. The fork length (FL) ranged 9.8 21.4 cm the body weight (W) 13.62 200.68 g. Based on lapillus readings, maximum age was 7 years. overall ratio female male 1:0.16. von Bertalanffy equation parameters calculated as L∞ = 39.32 cm, W∞ 1504.92 g, k 0.08, t0...
