Summary The oomycete A phanomyces astaci is generally considered a parasite specific to freshwater crayfish, and it has become known as the crayfish plague pathogen. Old experimental work that reported transmission of C hinese mitten crab E riocheir sinensis , ability . grow in non‐decapod crustaceans, never been tested properly. We re‐evaluated host range by screening for presence two species cohabiting with infected fresh waters, well other higher crustaceans from such localities. animals...
Many populations of the narrow-clawed crayfish Astacus leptodactylus in Turkey, including those inhabiting Lake Eğirdir, declined drastically mid-1980s due to introduction plague Aphanomyces astaci. However, unlike many other localities, there has been some recovery A. population this lake even though suspected have persisted since then. In support this, DNA from 5 34 healthy-looking sampled recently tested positive by both conventional and real-time PCR using species-specific primers...
An experiment was conducted to evaluate effects on growth, body composition and nutrient digestibility of addition protease phytase soybean meal-based diet in rainbow trout. Seven diets were prepared by adding protease, mixture both enzymes at two different levels (1 2 g kg−1) a base without enzymes. Mixed (1, the same doses (0.5 + 0.5 1 kg−1). Diets consisted 31% fish meal 44% dehulled hexane extracted meal. At start experiment, 45 trout (initial mean weight 88 g) stocked into each 21 fibre...
Otolith weight (OWe) asymmetry plays a crucial role in the vestibular function of inner ear, potentially affecting its performance. Typically, OWe values range from −0.2 to +0.2 (−0.2 < X +0.2). In this study, we collected 136 fish specimens Gulf Antalya, located along Mediterranean coast Turkey, which included species Nemipterus randalli, Boops boops, Scorpaena elongata, and notata. Our findings revealed that level these four teleost increases with total length (TL) fish. Evaluating is...
Abstract Otoliths from four species of scorpaenids– Helicolenus dactylopterus (Delaroche, 1809), Scorpaena elongata Cadenat, 1943, notata Rafinesque, 1810, and scrofa Linnaeus, 1758–were collected Antalya Bay along the Mediterranean coast Türkiye. The fish were captured using a commercial bottom trawl net with mesh size 44 mm (22 in cod end). fishing grounds varied depth 40 to 160 meters. Scanning electron microscopy (SEM) images utilized analyse otoliths’ characteristics. Twenty‐one...

Abstract: The present experiment was conducted to describe the effects on histology (experiment 1) and nutrient digestibility 2) of rainbow trout fed with diet containing O. onites oil. Diets were prepared supplemented in different concentrate (0, 0.125, 1.5, 2.5, 3.0 ml kg-1) A total 1050 (body weight 26.05 ± 0.15 g) randomly stocked into 15 tanks. experiments done triplicate. In 1, during 90 day for analysis. Five fish samples from per tank taken at end experiment. Liver kidney...
A 12-week feeding trial was conducted with 87 g rainbow trout to evaluate the effects on growth performances, feed efficiency and nutrient digestibility of adding β-mannanase α-galactosidase enzymes, solely or in combination. Seven diets were prepared by β-mannanase, mixed enzyme at two different levels (1 g/kg 2 g/kg) control diet (without enzyme) including soybean meal. Mixed enzymes g/kg, same doses (0.5+0.5 1+1 g/kg). At end experiment, addition containing 44% meal had no significant...
As alternative to formalin, the antifungal effect of a plant product [Origanum onites L. (Lamiaceae) oil] was investigated for use in artificial incubation narrow-clawed crayfish (Astacus leptodactylus Eschscholtz) eggs. For this purpose, study conducted as two experiments. In experiment I, eggs were artificially incubated 40 days. II, juveniles cultured determine effects O. oil on 30 The experimental groups follows: formalin (3500 ppm 15 min), (300 min, 700 2 min and 1000 dip treatment...
Effects of interaction season, sex and size on nutrient composition fatty acid profiles freshwater crayfish (Astacus leptodactylus) caught from the Eğirdir Lake were investigated a factorial level. In analysis; 4 levels season factors (autumn, winter, spring, summer), 2 factor (male, female) 1 level available. According to results biochemical analysis, effects seasons determined crude protein moisture levels. Crude ash changed depending season. There no interactions these three fat The...
Graecoanatolica Radoman, 1973 is a remarkable genus of Hydrobiidae, recognized with its disjunct distribution between Macedonia, Greece (Thessaly), and Turkey (Lakes Region). However, the current restricted to Turkey, as 2 Balkan species have been declared extinct. In this study, taxonomic revision in presented. Among 6 previously species, G. conica brevis from provinces Denizli Burdur are determined be anatolica (Schütt, 1965) comb. nov. transferred dinarica sp. described new....
This study was conducted to investigate effects of different ratios red pepper (Capsicum annuum) on the growth performance, feed conversion ratio (FCR), hepatopancreas histopathology, skin and tail coloration jewel cichlid (Hemichromis guttatus). Five isonitrogenous (370 g/kg1) isoenergetic (3831 kcall/kg−1) experimental diets were prepared by adding 3%, 7%, 11% % 15 peppers diet. In experiment, fifteen fish (initial weight 3.43 ± 0.03 g) stocked into each aquarium as three replicate. The...
The aim of this study was to investigate the combined effects two stocking densities (650 and 1300 juveniles/m 2 ) diets (live feed - Daphnia magna commercial trout feed) on survival rate growth performance Astacus leptodactylus juveniles. Juveniles in second developmental stage were used experiment. Final paremeters juveniles evaluated at end experiment (90 days). results indicated that not found effective rates, though increasing stock reduced rates. best final as 21.99 %, achieved group...
