Abstract

Sailfin molly, Poecilia latipinna is one of the alien ornamental fishes in Indonesia. This fish has been found in the aquaculture area in Maros Regency, south Sulawesi as a pest. The research aimed to identify species and observe aspects of reproductive biology of sailfin molly. The study was conducted in the Bosowa Isuma aquaculture area, in Maros Regency from November 2017 to April 2018. Fish was captured using a gillnet. The catches were separated for fish identifying and reproductive biology purposes. For the observation of reproductive biology, the samples were separated by sex according to external morphology. Measurement of total length and weight using calliper (mm) and analytical scales (g), respectively. The gonads preserved in the 4% formalin solution, used for determination of gonad developmental stages and fecundity. Identification results showed that the molly fish found in the ponds was Poecilia latipinna (Lesueur 1821). The length distribution of male and female fish was 26-76 and 31-66 mm with a mean of 51 and 46 mm, respectively. Overall, sex ratio and mature gonads between male and female fish were 1: 2 and 1:10; the growth patterns of male and female were negative allometrics and isometric, respectively. This fish is spawn throughout the year with the peak of spawning in January. The number of larvae to be born (larval fecundity) ranges from 12-111 individuals with an average of ± 32 larva/female. Abstrak Ikan molly, Poecilia latipinna adalah salah satu ikan hias asing di Indonesia. Ikan ini telah ditemukan masuk di areal pertambakan di Kabupaten Maros Sulawesi Selatan sebagai hama. Penelitian bertujuan untuk mengidentifikasi spesies dan mengamati aspek biologi reproduksinya. Penelitian berlangsung dari November 2017-April 2018 di areal pertambakan Bosowa Isuma Kabupaten Maros. Pengambilan sampel menggunakan jaring insang. Sampel dipisahkan untuk tujuan identifikasi dan pengamatan biologi reproduksinya. Untuk pengamatan biologi reproduksi sampel dipi-sahkan berdasarkan jenis kelamin dengan mengamati morfologi tubuh. Pengukuran panjang total menggunakan mis-tar geser dan penimbangan bobot dengan timbangan analitik. Gonad diawetkan dalam larutan formalin 4% digunakan untuk penentuan tingkat kematangan gonad dan fekunditas. Hasil identifikasi menunjukkan bahwa ikan molly yang ditemukan adalah jenis Poecilia latipinna (Lesueur 1821). Sebaran ukuran panjang ikan jantan dan betina adalah 26-76 dan 31-66 mm dengan rataan 51 dan 46 mm. Nisbah kelamin secara keseluruhan dan yang matang gonad (TKG IV) antara ikan jantan dan betina adalah 1 : 2 dan 1 : 10; pola pertumbuhan jantan dan betina adalah allometrik negatif dan isometrik; memijah sepanjang tahun dengan puncak pemijahan pada bulan Januari. Jumlah larva yang akan dila-hirkan (larval fecundity) berkisar 12-111 ekor dengan rata-rata ± 32 ekor larva/induk.

Abstract

The high exploitation pressure and decreasing environmental conditions of Lake Tempe due to pollution, sedimentation, growth of aquatic weeds, and the presence of invasive alien fish, namely suckermouth catfish, are thought to have harmed one of the native fish, namely climbing perch (Anabas testudineus). The research aims to analyze the reproductive biology of climbing perch. Fish were caught using gill nets from January to April 2021. The total length of the fish was measured using a caliper (cm), and the weight (g) was measured using an analytical balance. Fish gonads were preserved in a 4% formalin solution. Fish fecundity was calculated based on the gravimetric method. The length distribution of male and female fish was 7.5 - 15.5 and 7.5 - 17.5 cm, respectively. The maximum climbing perch caught was 17.5 cm smaller than the maximum length ever caught, which was 35.0 cm, and the average size was 9.56 cm smaller than the average length of climbing perch, which was 12.5 cm. The ratio of male and female fish as a whole was 1.1: 0.9 or 53%: 47%, while the sex ratio of males and females in spawning was 38%: 62%. Climbing perch is polygamous, i.e., male fish have several partners in one spawning season. The spawning season lasted throughout the research period, with the spawning season's peak in February with a total spawner pattern. Fecundity ranged from 253-10,237 eggs with an average value of 2,571 eggs, and the relationship between length and weight with fecundity was very strong. The growth pattern of male and female fish was negative allometric. Abstrak Tekanan eksploitasi yang tinggi dan kondisi lingkungan Danau Tempe yang semakin menurun akibat pencemaran, sedimentasi, pertumbuhan gulma air, dan hadirnya ikan asing invasif, yaitu ikan sapu-sapu, diduga telah memberikan pengaruh buruk terhadap salah satu ikan asli yaitu ikan betok (Anabas testudineus). Penelitian bertujuan untuk menganalisis kondisi biologi reproduksi ikan betok. Ikan sampel ditangkap menggunakan jaring insang dari Januari-April 2021. Panjang total ikan diukur dengan jangka sorong (cm) dan bobot ditimbang (g) dengan timbangan analitik. Gonad ikan diawetkan dalam larutan formalin 4%. Fekunditas ikan dihitung berdasarkan metode gravimetrik. Sebaran ukuran panjang ikan jantan dan betina masing-masing 7,5 - 15,5 dan 7,5 - 17,5 cm. Panjang maksimum ikan betok yang tertangkap yaitu 17,5 cm lebih kecil dari panjang maksimum yang pernah tertangkap yaitu 35,0 cm, dan panjang rata-rata yaitu 9,56 cm lebih kecil dari panjang rata-rata ikan betok yaitu 12,5 cm. Nisbah ikan jantan dan betina secara keseluruhan sebesar 1,1 : 0,9 atau 53% : 47%; sedangkan nisbah kelamin jantan dan betina dalam pemijahan yaitu 38% : 62%. Ikan betok bersifat poligami yakni ikan jantan memiliki beberapa pasangan dalam satu musim pemijahan. Musim pemijahan berlangsung sepanjang bulan penelitian dengan puncak musim pemijahan pada Februari dengan pola pemijah serentak. Fekunditas berkisar antara 253- 10.237 telur dengan nilai rata-rata 2.571 telur. Hubungan panjang dan bobot dengan fekunditas sangat kuat.Pola pertumbuhan ikan jantan dan betina adalah allometrik negatif.
