Pengaruh Penangkaran terhadap Profil Eritrosit Lumba-lumba Hidung Botol dari Perairan Laut J awa = The Influence of the Captivity in Bottlenose Dolphin Erythrocytes Profile from The Waters of The Java Sea

Abstract

Di laut Jawa banyak populasi lumba-lumba yang sering tersangkutjala para nelayan saat mencari ikan di laut. Di Indonesia, lumba lumba hidung botol merupakan mamalia air yang dilindungi. Penelitian ini bertujuan untuk mengetahui profil eritrosit bottlenose dolphin (lumba-lumba hidung botol) sebeluni dan setelah penangkaran. Tujuh ekor lumba-lumba digunakan dalam penelitian ini. Sampel darah diambil melalui vena superfisialis sirip ekor guna pemeriksaan eritrosit, meliputi jumlah, morfologi, kadar hemoglobin dan hematokrit. Pengambilan sampel dilakukan saat lumba-lumba diangkat dari perairan Laut Jawa dan setelah lumba-lumba mengalami penangkaran di PT. WSI, Kendal, Jawa Tengah. Data sebelum dan sesudah penangkaran dibandingkan dan diuji dengan analisis statistik t-test berpasangan pada tingkat signifikasi 95%. Hasil penelitian menunjukkan adanya peningkatan jumlah eritrosit, kadar hemoglobin dan nilai hematokrit secara signifikan. Dari hasil penelitian ini dapat disimpulkan bahwa penangkaran yang dilakukan oleh PT.WSI, Kendal, Jawa Tengahmeningkatkan profil eritrositlumba-lumba hidungbotol. In the Java Sea, there are a lot of dolphins, that often snagged fishing nets. While In Indonesia, bottlenose dolphins are mammals protected water. The aims of this research was to study the erythrocytes profile in bottlenose dolphins before and after the captivity. Seven dolphins were used in this research. Blood samples were\u27 taken out from the superficial vein of tail for examination of the number of erythrocytes, hemoglobin levels and value ofhematokrit. Sampling was done when the dolphins appointed from the waters of the Java Sea and after experiencing dolphin captivity in PT. WSI, Kendal, Central Java. The data before and after captivity were compared and tested with the statistical analysis on the level of significance of the paired t-test 95%. The results showed the significant increase in the number of erythrocytes, hemoglobin levels and the values ofhematokrit significantly. It was concluded that captivity done by WSI Corporation, Kendal, Central Java did increase the profile of erythrocytes inbottlenose dolphins
