Abstract

Research on the reproductive biology of fish can provide information on spawning frequency, spawning success, spawning time, and size at first maturity. This research aimed to determine the reproductive biology of common dolphinfish (Coryphaena hippurus Linnaeus, 1758) landed at the fish landing site (PPI) Kedonganan, Badung, Bali. Sampling was conducted in May - September 2018. A total of 42 female common dolphinfish with length ranged between 41-110 cm FL were obtained from hand-line fishery based on FADs. Ovaries were prepared using the paraffin method and Harris Haematoxylin-Eosin staining for histological observation. The results showed that the gonad maturity level in adult females was: spawning (38.10%), spawning capable (35.71%), regressing-potentially reproductive (4.76%), regressed 1 (2.38%), regressed 2 (2.38%), and regenerating (2.38%). Immature female: immature (9.52%) and developing (4.76%). Oocyte diameter ranged between 43,20 – 864,66 µm with an average of 430,99 µm. Fecundity in fish size 49-75 cm FL ranged from 30,720-433,080 eggs / fish with an average of 129,594 eggs / fish. The difference in the level of oocytes in the ovaries at the same time showed that female common dolphinfish in the southern Bali waters has an asynchronous ovary development and indeterminant fecundity with multiple spawning strategies and size at first maturity (Lm50) was 43.2 cm FL. Keywords: common dolphinfish, gonad histology, size at maturity

Abstract

Fenomena migrasi burung pemangsa merupakan fenomena yang terjadi dua kali setiap tahun, yaitu migrasi musim gugur (autumn migration) dan migrasi musim semi (spring migration). Di Indonesia, migrasi musim gugur dikenal juga dengan istilah migrasi arus datang, sedangkan migrasi musim semi dikenal dengan istilah migrasi arus balik. Penelitian ini bertujuan untuk mengetahui jenis burung pemangsa yang melintas di Gunung Sega, Karangasem Bali pada migrasi arus datang tahun 2018. Penelitian dilakukan pada tanggal 1 Oktober – 30 November 2018 di Gunung Sega Karangasem Bali dengan menggunakan metode dari Hume (1993). Jenis burung pemangsa yang tercatat adalah 7 jenis, yang terdiri dari 5 jenis migran dan 2 jenis penetap. Jenis migran yaitu elang-alap cina (Accipiter soloensis), elang-alap nipon (Accipiter gularis), elang sikep madu asia (Pernis ptilorhynchus), alap-alap kawah (Falco perigrinus) dan elang ular jari pendek (Circaetus gallicus). Burung pemangsa jenis penetap yang tercatat yaitu elang ular bido (Spilornis cheela) dan alap-alap sapi (Falco moluccensis). Kata kunci: Accipiter, burung pemangsa, Gunung Sega, migrasi

Abstract

Bali Starling (Leucopsar rothschildi Stresemann, 1912) is an endemic bird in Bali, which is categorized as critical (Critically endangered). Starting in 2006 Bali starling conservation efforts were also carried out in the Nusa Penida Islands. This study aims to study contribution of the customary village regulation (awig-awig) to the success of the conservation of Bali Starling in the Nusa Penida Islands. Methods used included calculation of the Bali starling population directly with concentrated methods and the awig-awig implementation in the community obtained using AHP (Analytical Hierarchy Process). Results of the study showed that the population of Bali Starling in 2006 was 49, while in 2015 there were 66 individuals. Awig-awig has been the most important alternative to protect Bali starling. The conclusion of this study is that the Bali Starling population is increasing, and the Nusa Penida Islands community has a perception, and good participation in the awig-awig who protect the Bali Starling.

Abstract

Tongkol lisong (Auxis rochei Risso, 1810) adalah satu jenis ikan tuna neritik yang terdapat di perairan Samudera Hindia selatan Jawa. Tingkat pemanfaatan pada saat ini diduga telah mencapai fully exploited. Penelitian tongkol lisong dilakukan untuk memperoleh data biologi reproduksi meliputi perkembangan gonad betina, fekunditas dan pemijahan di perairan selatan Bali sebagai bahan masukan bagi pengelolaan. Penelitian dilakukan pada bulan Juni-November 2021, melalui pengambilan contoh dari hasil tangkapan yang didaratkan di PPI Kedonganan, Bali. Sebanyak 151 ekor ikan betina dari total sampel 317 ekor (panjang 15-35 cmFL) telah diteliti. Sampel gonad segar difiksasi dan dianalisis secara histologis melalui metode parafin dengan pewarnaan Harris-Haemotoxilin dan Eosin. Tongkol lisong mempunyai tipe pemijahan ganda dengan kematangan oosit tidak seragam, ditandai adanya beberapa tingkat kematangan oosit dalam satu ovarium. Tongkol lisong betina yang belum matang gonad memiliki oosit unyolked dan early yolked berdiameter antara 41-179 µm; gonad ikan betina dewasa memiliki oosit lebih matang yaitu advanced yolked (AY) berdiameter antara 275-328 µm, mempunyai migratory nucleus berdiameter antara 475-514 µm dan hydrated berdiameter sekitar 554 µm. Secara makroskopis tongkol lisong betina berpijah sejak bulan Juli dengan kontribusi 32%. Pengamatan mikroskopis menunjukkan pemijahan telah berlangsung sejak Juni hingga Oktober, puncak pemijahan Juli-Agustus denga kontribusi 52% dari total ikan betina yang diamati. Dugaan fekunditas dengan oosit migratory nucleus dan hydrated yang dikeluarkan berkisar antara 5.062-229.707 butir telur/ekor atau rata-rata 81.351 butir/ekor.Bullet tuna (Auxis rochei) is one of the neritic tuna species in the Indian Ocean south of Java. At present, its exploitation rate of its has reached fully exploited. This study was conducted to obtain the data on reproductive biology related to the gonadal (ovaries) development, fecundity and spawning in the southern waters off Bali as the input for management. The research was conducted from June to November 2021 by biological fish sampling from the catch landed. About 151 females fish from a total of 317 fishes ranging between 15-35 cm FL could be observed. The fresh gonad samples were fixed and analyzed histologically by the paraffin method with Harris-Haemotoxilin and Eosin’s staining. Bullet tuna is a multiple spawner type with asynchronous oocyte development. The immature female fish have an unlocked and early yolked oocytes with 41-179 µm in diameter; the mature ovaries have oocytes in a higher level of maturity, namely advanced yolked (275-328 µm in diameter), migratory nucleus (475-514 µm in diameter), and hydrated oocytes (about 554 µm in diameter). Macroscopically, the female bullet tuna spawned in July, characterized by decreasing GSI value and the presence of ovaries in the maturity stage IV (mature) and V (spent), with a contribution of 32% of total females landed. The microscopic observations during the sampling periods showed that spawning, characterized by the emergence of spawning development classes, took place from June to October. The peak of spawning was around July-August, where 52% of the total females landed—estimating fecundity (number of mature eggs released during spawning) with that migratory nucleus and hydrated oocytes in between 5,062-229,707 eggs/individual with an average of 81,351 eggs/individual.

Abstract

Burung Kasuari Gelambir Ganda (Casuarius casuarius Linnaeus, 1758) merupakan satwa endemik yang keberadaannya memiliki pengaruh besar dalam ekologi hutan di Papua. Sebagai frugivora, burung ini berperan untukmenyebarkan biji pohon buah-buahan yang merupakan 90% dari spesies pohon di hutan Papua. Namun populasi burung ini di habitat alaminya mengalami penurunan akibat konversi hutan seiring perkembangan penduduk, dan diperparah oleh perburuan oleh masyarakat setempat. Konservasi ex-situ dilakukan dengan tujuan untuk mengembangbiakkan satwa di luar habitat aslinya, sehingga penelitian aktivitas harian spesies burung Kasuari Gelambir Ganda perlu dilaksanakan. Penelitian dilakukan dari tanggal 10 Januari sampai 21 Februari 2022 terhadap lima individu burung Kasuari Gelambir Ganda di Bali Zoo. Metode yang digunakan yaitu focal animal sampling dengan instantaneous recording selama 30 menitdengan interval waktu satu menit. Data yang diperoleh ditabulasi dan dianalisis menggunakan Microsoft Excel, kemudian dijabarkan secara deskriptif. Aktivitas yang paling banyak dilakukan oleh burung Kasuari Gelambir Ganda di Bali Zoo adalah istirahat (35,69%), dilanjutkan dengan aktivitas bergerak (19,69%), mencari makan (18,58%), menelisik bulu (16,74%), waspada (6,69%), vokalisasi (1,19%), defekasi (0,48%), dan urinasi (0,14%). ini menunjukan bahwa burung Kasuari Gelambir Ganda dapat merefleksikan aktivitas hariannya secara alami selama berada di lembaga konservasi Bali Zoo yang mengindikasikan kesejahteraan satwa terpenuhi.
