Determination of spermatological properties of male Liza abu (Heckel, 1843) in Atatürk Dam Lake, Şanlıurfa

Abstract

The aim of this study was to determine the spermatological characteristics in male L. abu during the spawning season. Semen was collected weekly by abdominal massage from 26 males in March. In collected semen, volume, motility, duration of motility, concentration and pH were determined. In the L. abu sperm, volume (microl), motility (%), duration of motility (s), concentration (x10(9)/ml), and pH values were found 45.76 +/- 3.55, 54.25 +/- 2.93, 330.15 +/- 37.92, 4.27 +/- 0.40 and 7.87 +/- 0.05, respectively. A correlation was found between semen volume and semen pH. Semen volume and the duration of sperm motility were higher in the 2nd and 3rd sampling dates than in the 1st and 4th sampling dates (P < 0.05; P < 0.01, respectively). Neither sperm motility nor sperm concentration was affected by sampling dates. Major changes in semen pH were observed in the 4th sampling date (P < 0.001). The Pearson correlation test presented significant relationships with the duration of motility, semen volume, and motility. Semen pH values were significantly correlated with the sperm concentration and semen volume. Sperm concentration was inversely correlated with semen volume. Sperm motility and duration significantly correlated with total weight. Total length significantly correlated with the duration of motility and total weight. In conclusion, these characteristics represent a valuable baseline dataset for establishing a semen quality standard and provide background information that may be useful for assisted breeding programs in this species.

Fertilization by refrigerator stored sperm of the Indian major carp,Labeo calbasu(Hamilton, 1822)

“…Similar results have been found for other carp species (Khanam, Nahiduzzaman, Hassan, Sultana, Rafiquzzaman & Hossain 2008;Verma et al 2009). Seminal plasma pH of L. calbasu was slightly alkaline and is similar to other teleosts, including Puntius sarana (Khanam et al 2008), Liza abu (Sahinoz, Aral & Dogu 2008) and Ctenopharyngodon idella (Bozkurt, Ogretmen, Ercin & Yildiz 2008).…”

Changes of sperm quality parameters in Caspian roach (Rutilus rutilus caspicus) during spawning migration

“…Seminal plasma pH may affect final maturation of spermatozoa. Also, duration of sperm motility in males could be influenced by the changes of semen pH (Sahinoz et al, 2008). In cyprinids, it has been shown that extracellular and intracellular pH as well as the ionic composition of the seminal plasma influence the initiation and duration of sperm motility (Marian et al, 1997).…”

Some aspects of the biology of Abu mullet Liza abu (Heckel, 1843) in the Orontes River, Turkey

“…Deviations from 1:1 null hypothesis were statistically tested using the chi-square analysis ( 2 -test) (Av ar, 1995). The von Bertalanffy growth equations were used to describe growth of the species (Sparre and Venema, 1992):…”

“…It is a target of a commercial fishery because of high economic importance (Abd et al, 2009). Despite intensive investigations of the growth, reproduction and ecology of abu mullet in the Tigris and Euphrates Rivers (Al-Nasırı and Sirajul, 1978;Al-Yamour et al, 1988;Ünlü et al, 2000;ahinöz et al, 2008;Chelemal et al, 2009;Kaya, 2010;ahinöz et al, 2010) and other places in the Arabian Gulf and marshes (Nasır and Naama, 1988;Naama and Muhsen, 1986), information on growth, age and reproduction of abu mullet in the Orontes River is still not available. The aim of this study is to provide information on the biological aspects of abu mullet inhabiting the Orontes River basin.…”
