Abstract

Penyu adalah satwa yang terancam punah, sehingga upaya konservasinya perlu ditingkatkan. Kegiatan yang berhubungan dengan konservasi dimaksud adalah rehabilitasi penyu pascamengalami periode out of the water sebelum dilepasliarkan kembali ke alam bebas. Penelitian ini bertujuan untuk mengetahui perbedaan profil dan indeks eritrosit penyu hijau (Chelonia mydas) sebelum dan sesudah mengalami rehabilitasi di Turtle Conservation and Education Center (TCEC) di Pulau Serangan, Denpasar. Penelitian ini menggunakan sampel Sembilan ekor penyu hijau hasil sitaan Polisi Sektor Kuta, Badung, Bali. Sebanyak 2,5 mL darah perifer penyu hijau diambil dari sinus cervicalis dorsalis disimpan di tabung berisikan antikoagulan litium heparin dan dilanjutkan dengan pemeriksaan hematologi. Penentuan nilai total eritrosit dihitung dengan hemositometer. Kadar hemoglobin (Hb) diukur menggunakan Hemoglobinometer Sahli, sedangkan kadar Packed Cell Volume (PCV) ditentukan dengan metode mikrohematokrit. Indeks eritrosit yang meliputi Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) dan Mean Corpuscular Haemoglobin Concentration (MCHC) dihitung dengan rumus konvensional yang ditentukan untuk itu. Data hasil penelitian dianalisis secara deskriptif kuantitatif menggunakan uji T berpasangan. Nilai profil darah (Packed Cell Volume, total eritrosit, Hemoglobin) mengalami peningkatan signifikan pasca rehabilitasi dengan nilai rerata hematokrit sebelum rehabilitasi sebesar 28,4±3,09 menjadi 31,7±2,87, nilai total eritrosit sebelum rehabilitasi sebesar 0,44±0,10 menjadi 0,56±0,15, nilai Hemoglobin sebelum rehabilitasi sebesar 6,3±1,28 menjadi 7,53±0,73 serta hasil perhitungan secara statistika dengan uji T-berpasangan menunjukkan profil darah penyu hijau sebelum dan sesudah rehabilitasi memiliki perbedaan yang signifikan yang berarti proses rehabilitas yang dilakukan di Turtle Conservation and Education Center, Serangan berhasil.

Abstract

This study aimed to evaluate the effects of ex-situ habitat transfer on physiological and behavioral stress responses in Indo-Pacific bottlenose dolphins (Tursiops aduncus) and to assess the effectiveness of environmental enrichment in mitigating stress and enhancing welfare. Seven dolphins were monitored across four periods: before transfer, immediately upon arrival at the new facility, after 15 days of adaptation, and following 30 days of environmental enrichment using interactive toys. Parameters measured included neutrophil-to-lymphocyte (N/L) ratio, respiratory rate, frequency of stereotypic behaviors, food intake, social interactions, and compliance with trainer commands. The results demonstrated that habitat transfer induced significant increases in N/L ratio and respiratory rate. A 15-day adaptation period was insufficient to restore physiological and behavioral parameters to baseline levels. However, after 30 days of environmental enrichment, stress indicators improved markedly, with decreased N/L ratios, normalized respiratory rates, reduced stereotypic behaviors, and increased food intake, social interactions, and compliance. These findings underscore the importance of integrating structured environmental enrichment strategies into ex-situ conservation and management programs to support optimal welfare in captive dolphins.
