Abstract

Turtles are one of the living fossils whose population conditions are currently in a worrying state. Several factors that threaten the turtle population include illegal trade, water pollution, global climate change, and fishing activities. TCEC is a non-governmental institution that has a turtle rescue program as a conservation effort. TCEC has rescued turtles from various threats. The purpose of this study was to determine the types of threats, types of threatened turtles, the number of turtles rescued and the appropriate medical actions in efforts to rescue and rehabilitate turtles carried out by TCEC. Turtle rescue data was inventoried from 2015 - April 2025. Data analysis carried out included the number, types of turtles rescued and the types of threats for each year. This data can provide an overview of the background and context that are important for understanding cases of turtle rescue from various threats encountered by TCEC. The number of turtles successfully rescued by TCEC was 287. The number of turtles rescued from the threat of bycatch was 4 individuals, stranded as many as 43 individuals and from illegal trade as many as 238 individuals. Each rescued turtle will receive medical treatment appropriate to the turtle's condition from a veterinarian and after its condition has recovered, it will be released into its habitat. Illegal trade is still a very big threat to the turtle population. These results indicate that turtle conservation stakeholders must continue to run campaigns related to the eradication of turtle trade and educate the public to raise awareness to stop consuming turtles.

Abstract

Ikan tawes (Barbonymus gonionotus) merupakan spesies asli Indonesia yang diintroduksi ke perairan Danau Batur. Informasi terkait ikan tawes di perairan Danau Batur belum ada sebelumnya, meski penelitian terhadap spesies ikan ini di ekosistem perairan lainnya sudah banyak dipublikasikan. Tujuan dari penelitian ini adalah untuk mengungkapkan hubungan karakter panjang, pola pertumbuhan dan kondisi ikan tawes di Danau Batur. Pengambilan contoh ikan dilakukan selama tiga kali selama periode bulan Oktober 2017–Juni 2018 dengan interval tiga bulan. Pengambilan contoh ikan dilakukan dengan jaring insang eksperimental. Total sampel ikan tawes yang berhasil tertangkap adalah 577 ekor. Kisaran ukuran panjang total, panjang cagak dan panjang baku ikan tawes di Danau Batur masing-masing adalah 50–178 mm, 45–158 mm dan 37–142 mm. Hubungan antar karakter panjang memiliki korelasi yang kuat dan ketiganya dapat digunakan untuk menduga bobot ikan tawes dengan presisi yang tinggi. Pola pertumbuhan ikan tawes di Danau Batur adalah allometrik positif. Ikan tawes di Danau Batur berada dalam kondisi yang baik dengan kisaran nilai faktor kondisi antara 0,78–1,80.
