Abstract

Candi Borobudur adalah salah satu situs warisan budaya dunia yang memiliki 1460 relief yang memuat kehidupan pada zaman itu. Mempelajari relief-relief di Candi Borobudur, diharapkan dapat memperoleh informasi mengenai aktivitas perikanan pada masa lalu dan dapat diterapkan pada saat ini. Penelitian ini dilakukan dengan metode eksplorasi secara langsung pada relief Candi Borobudur. Berdasarkan pengamatan didapatkan beberapa aktivitas penangkapan ikan yang umum dilakukan di Indonesia, yaitu menangkap ikan menggunakan bubu, jaring, dan pancing. Menangkap ikan menggunakan jaring cenderung kurang selektif dan dapat mengakibatkan penangkapan ikan yang tidak diinginkan atau yang belum mencapai ukuran dewasa, menangkap ikan menggunakan bubu dan pancing dianggap lebih ramah lingkungan dan selektif, karena nelayan dapat memilih jenis ikan yang ingin ditangkap dan melepas kembali ikan yang tidak diinginkan.

Abstract

Spiny Eel (Mastacembelidae family) is a freshwater fish that lives in various types of waters. Spiny eel is a potential fish that is still very rarely researched and developed. Continuous fishing has resulted decreasing number on spiny eel in the nature. This study aims to find out how the ecological and biological aspect of spiny eel in the Elo River, Magelang City, Central Java. This study used a random sampling method with minimum sample of 30 spiny eel from the wild. Data collection techniques were carried out by direct observation and by conducting a review of previous research literatures. The research results showed that the habitat of the spiny eel in the Elo River was suitable for the spiny eel to live in. There were three types of spiny eel obtained, namely Macrognathus circumcinctus, Macrognatus maculatus dan Mastacembelus unicolor with a total number of 36. Spiny eel has a negative allometric length growth pattern. The sex ratio of the spiny eel is 1.4:1. The majority of gonadal maturity level are in second stage. The average of GSI (gonadosomatic index) of male and female were 0.727% and 1.621%. Fecundity of female fish ranged from 2614 – 46233 eggs. Theoritical age is divided into three, Macrognathus circumcinctus, Macrognatus maculatus dan Mastacembelus unicolor have the average of 3.8, 7.27 and 4.67 months. Spiny eel really loved worms and crustaceans (crab and shrimp / prawn) as their main feed (IP 38.83%) and (IP 39.67%) then shrimp / prawn as their complementary feed (IP 14,63%) aquatic microinvertebratae for their additional feed (IP 4.73%) and left with unidentified feed (IP 1.15%).
