Determination Of The Selectivity Of Monofilament Gillnets Used For Catching The Annular Sea Bream (Diplodus Annularis L., 1758) By Length-Girth Relationships In İzmir Bay (Aegean Sea), Uğur Özeki̇nci̇

Turkish Journal of Veterinary & Animal Sciences

Annular sea bream (Diplodus annularis L., 1758) is one of the most abundant species among demersal fishes in the Aegean Sea. The object of this study was to determine the selectivity parameters of 52-54-56 mm stretched mesh size monofilament gillnets used for catching the annular sea bream in the İzmir Bay in the Eastern Aegean Sea. Selectivity curves were determined using Sechin method, which estimates probability of fish retention as a function of morphometric features of the body between head and maximum girth of fish. The estimated selectivity curves corresponded well with size frequencies obtained from each mesh size. The …

Effects Of Egg Weight And Length Of Storage Period On Hatchability And Subsequent Laying Performance Of Quail, Meti̇n Petek, Hasan Başpinar, M. Mustafa Oğan, Faruk Balci

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to investigate the effects of hatching egg weight and length of egg storage period on hatchability and subsequent laying performance of quails. Eggs were collected from a quail flock (Coturnix coturnix Pharaoh) aged 17 weeks and classified into 4 groups on the basis of storage period 1, 3, 5, or 7 d. Prior to egg storage, the eggs in each group were further divided into egg weight treatment (small: 12.51 g). Hatchability of total and fertile eggs was affected significantly by hatching egg weight (P < 0.05) but was not affected significantly by the length of egg storage period. There was a decrease in egg production associated with increase in hatching egg weight. Egg production of quails hatched from stored eggs for 3 days was greater than the other groups. There was a significant interaction between hatching egg weight and length of egg storage for egg production. It was concluded that medium eggs can be hatched satisfactorily after 3 days storage for optimum egg production in quails.

Effects Of Interleukin 1(Il1)-Induced Matrix Breakdown On Chondrocyte Morphology In Bovine Nasal Cartilage Explants, Di̇dem L. Kozaci, Gülgün Oktay, Anthony P. Hollander

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to investigate the influence of matrix loss on regulating chondrocyte phenotype, and the synthesis and activation of collagenolytic enzymes. IL1 was used to enhance matrix breakdown in bovine nasal cartilage explants. Change in matrix composition and its effects on chondrocyte morphology were investigated using histochemical techniques. In bovine nasal explants, chondrocytes responded to IL1 to manifest 2 distinct patterns of cell shape exhibiting either pyknotic or enlarged nuclei. Enzyme activity analysis suggested a positive correlation between collagenolytic activity and the occurrence of proteoglycan loss and cell morphology changes. These data suggest that loss of …

Immune Responses In Mice Immunized Intranasally With Sendai Virus, Gazim Bizanov, Irena Jonauskiene

Turkish Journal of Veterinary & Animal Sciences

Mice were immunized 3 times intranasally (i.n.) at intervals of 2 weeks with a formalin-inactivated Sendai virus (SV) whole virus with and without whole formalin-inactivated Bordetella pertussis (Bp) as adjuvant. The antibody response to SV was measured using the hemagglutination inhibition (HI) test in serum, and the IgA and IgG antibodies were evaluated using enzyme linked immunosorbent assay in saliva and serum. It was demonstrated that repeating immunizations with SV plus Bp could induce HI serum antibodies, IgA and serum IgG antibodies. However, in mice immunized subcutaneously with SV alone, high serum IgG antibodies and HI titers were induced only. …

Turkish Journal of Veterinary & Animal Sciences

This study was carried out in Gözlen Creek, located on the Fethiye-Muğla boundary Turkey, between March to July, 1998, and January to July, 1999. Elvers were collected using trap-nets, drift nets, hand scoop nets and electrofishing equipment. Examination indicated that the highest yield was obtained using hand scoop nets (P < 0.05) and electrofishing equipment. Elvers entered Gözlen Creek between February and July. A total of 214 specimens entering the creek were examined and 3 different groups were established according to their morphological characteristics: average weight (W) group I; 0.166 ± 0.007 g, group II; 0.392 ± 0.02 g, group III; 0.800 ± 0.06 g and average total length (L) group I; 56.16 ± 0.06 mm; group II; 64.39 ± 0.11 mm and group III; 82.02 ± 0.18 mm. The length-weight relation of elvers was calculated using regression analysis and was determined as follows: group I; W = 0.0020*L^{2.5327}, group II; W = 0.0015*L^{2.9516}, and group III; W = 0.0023*L^{2.7090}. The condition factor (C) was determined as 0.209 ± 0.009 for group I; 0.154 ± 0.004 for group II and 0.251 ± 0.009 for group III.

Tinca tinca were exposed to lethal and sublethal treatments with mercury, cadmium and lead for acute and chronic periods to study alterations in immunological parameters. Acute lethal exposure (Lc_{50}/48 h ; 96-h Lc_{50} of Hg 1.0, Cd 6.5, Pb 300 ppm) caused a significant increase in Lct in the Hg treatment and a significant decrease in the Pb treatment, and a significant decrease in total WBC count in the Hg and Cd treatments. Lower acute sublethal exposures (10% Lc50/24 h), caused a significant increase in Lct in the Hg and Pb, treatments and a significant increase in total WBC count …

Growth And Feed Utilization In Juvenile Black Sea Turbot (Psetta Maeotica) Under Different Photoperiod Regimes, Ali̇ Türker, Murat Yi̇ği̇t, Sebahatti̇n Ergün

Turkish Journal of Veterinary & Animal Sciences

The effects of 4 different experimental photoperiod regimes, LDN (natural photoperiod), LD24:0 (24 h light:0 h dark), LD12:12 (12 h light:12 h dark) and LD0:24 (0 h light:24 h dark), on feed intake and growth parameters of juvenile turbot (21 ± 2.3 g) in the Black Sea were determined. Growth was highest in the group exposed to the continuous photoperiod (LD24:0), followed by the LD12:12, LDN and LD0:24 groups in descending order. The lowest growth rate was recorded in the LD0:24 group. According to the results obtained, LD24:0 and LD12:12 photoperiod exposures are best for better growth and food conversion …
