"kan Bada (Rasbora argyrotaenia) merupakan salah satu komoditas ikan asli di Danau Maninjau-Sumatera Barat. Ikan tersebut memiliki nilai ekonomis sebagai sumber protein masyarakat lokal, dan juga sangat berpotensi sebagai ikan hias. Kebutuhan terhadapnya selama ini masih mengandalkan hasil penangkapan, yang tentu saja sangat terbatas dan dikhawatirkan dapat menyebabkan penurunan populasi ataupun kepunahan bila tidak diimbangi dengan upaya pelestariannya. Usaha pelestariannya telah mulai dirintis dengan mencoba mengembangkannya. Penelitian ini ingin mengetahui kemampuan adaptasi ikan tersebut pada beberapa tingkat suhu media pemeliharaan, guna memprediksi kemampuannya dalam menghadapi pemanasan global apabila benar-benar berlangsung dan juga untuk mengetahi suhu terbaik untuk pengembangannya. Penelitian dilakukan pada bulan JuliOktober 2009 di Pusat Penelitian Limnologi-LIPI, Cibinong. Masing-masing 30 individu anak ikan bada umur 1,5 bulan dipelihara pada beberapa kisaran suhu air pemeliharaan yaitu: 24,526,0oC (kontrol);>2628 oC; >2830 oC; >3032 oC; dan >3234oC. Parameter adaptasi yang dianalisis yaitu ketahanan hidup dan pertumbuhannya. Hasil menunjukkan bahwa ikan bada mampu beradaptasi untuk hidup pada empat kisaran suhu dengan sintasan akhir antara 6070 persen, sedangkan pada kisaran suhu >3234oC ikan hanya mampu hidup selama 1 bulan dengan sintasan sebesar 19,85 persen, Pertumbuhan terbaik diperoleh pada kisaran suhu normal (kontrol) dengan pertumbuhan mencapai 30,74 mm atau pertumbuhan harian 0,256 mm/hari."

"ABSTRAKPenelitian mengenai dampak masuknya ikan asing telah dilakukan di Situ Kenanga, Agathis, Mahoni, Puspa, Ulin dan Situ Salam Universitas Indonesia, Depok, Jawa Barat pada bulan Maret ? April 2016. Penelitian bertujuan untuk mengkaji dampak masuknya ikan asing terhadap ikan lokal di Situ Kampus UI. Pengambilan sampel ikan dilakukan dengan menggunakan metode sampling bebas menggunakan Electrofishing gear, push net mata jaring 2,5 cm dan lift net. Hasil penelitian menunjukkan bahwa terjadi penurunan jumlah ikan lokal dan penambahan ikan asing yaitu ikan red devil (Amphilophus citrinellus) dan ikan aligator (Atractosteus spatula). Ikan red devil merupakan kompetitor bagi Aplocheilus panchax, Barbodes binotatus, Clarias batrachus, Oreochromis mossambicus, Oreochromis niloticus, Pterygoplichthys pardalis, Trichopodus pectoralis dan Trichopsis vittata sedangkan ikan aligator (Atractosteus spatula) merupakan predator yang rakus yang memangsa semua jenis ikan. Kedua jenis ikan tersebut berpotensi menjadi invasif karena memenuhi karakter sebagai invader sukses.

ABSTRAKA research study on the impact of introduced fish has been carried out in Lake Kenanga, Agathis, Mahoni, Puspa, Ulin and Salam at The University Of Indonesia, West Java from March to April 2016. The study aims to assess the impact of introduced fishes towards the native fishes that are living in those lakes. Fish sampling was conducted through a free sampling method by using an electrofishing gear, a push net with a 2,5 cm mesh and a lift net. The results showed that there was a decline in the number of native fishes and an increase of introduced fishes which are The Red Devil (Amphilophus citrinellus) and the aligator gar (Atractosteus spatula). The red devil is a competitor for Aplocheilus panchax, Barbodes binotatus, Clarias batrachus, Oreochromis mossambicus, Oreochromis niloticus, Pterygoplichthys pardalis, Trichopodus pectoralis and Trichopsis vittata while the aligator gar is a predator that preys on all kinds of fish. Both types of fish can potentially become invasive because they have many characteristics that make them a successful invader."

The research of fish community and its correlation with the production of mangrove forest litter in Panjang Island, Banten Bay had been conducted from October to December 2014 while spring tide. The research?s aim was to know the fish diversity and fish community, to identify mangrove litter?s value to the sea and correlation between C, N, P of mangrove litter and C, N, P of Chandidae (the biggest fish family captured). The method was used push net manually active and also water pipes were put to captured mangrove?s litter to the sea at Station 1 and 2. In total, 1770 species were captured (14 families, 16 genera, and 22 species), the most large number were at Station 1 and in November (1.213 and 749 individus). H? value at Station 1 was low (0,71), meanwhile at Station 2 was moderate (0,81). It supported by low E value. 51% fish captured was Ambassis gymnocephalus from Chandidae family. Economic value fish captured were Mugilidae and Serranidae. Mostly fish captured also were true resident fish (1.248). The biggest biomass of mangrove litter was been at Station 1 (162,99 g), while Chandidae was been at Station 2 (19,14 g). The biggest removed mangrove litter to the sea water was in December and Station 1 (47,47 g/m³/s). The Pearson correlation from C, N, P of mangrove litter and C, N, P of Chandidae gave the same value (0,999). The model of Linear Regression were Chandidae = 0,889 C Mangrove litter, Chandidae = 11,367 N Mangrove litter, dan Chandidae = 5,407 P Mangrove litter."

"[Ikan layur merupakan salah satu komoditas penting dalam perikanan tangkap di Palabuhanratu. Penelitian ini bertujuan menentukan populasi dan potensi ikan layur. Metode yang digunakan ialah data surplus produksi. Data ikan dibutuhkan untuk menggambarkan dinamika suatu populasi ikan yang dipengaruhi oleh pertumbuhan, mortalitas, dan migrasi ikan. Dinamika populasi dianalisis dengan paket perangkat lunak FISAT II dan pengkajian potensi lestari dianalisis denganmodel surplus produksi MSY. Hasil pengamatan Agustus-September 2014 menunjukkan perubahan kisaran panjang ikan dari kisaran 44,00?96,80 cm menjadi 47,00?97,99 cm dan berat rata-rata ikan berubah dari 285,33 gram menjadi 309,00gram. Perubahan panjang ikan ini karena ikan mengalami proses pemijahan. Hasil estimasi pada waktu pengamatan memperlihatkan bahwa laju eksploitasi populasi ikan layur belum mencapai tangkap lebih (overfishing) dengan nilai batas tingkat penangkapan dibawah optimum 0,50. Dalam rangka mewujudkan perikanan layur berkelanjutan, disarankan menetapkan musim penangkapan, penambahan upaya dan wilayah tangkapan, serta pendataan berbasis spesies.

Hairtail is one of the important fish catches in Palabuhanratu waters. This

study aims to determine the populations and potential of hairtail. To achieve these

objectives, it required accuracy and precision data. Data of fish are needed to describe

the dynamics of a fish population which influenced by fish growth, mortality, and

migration. The population dynamics is analyzed with FISAT II software package and potential sustainable surplus production is analyzed with MSY production surplus model. The observation result from August to September 2014 showed that fish length range has changed from 44.00-96.8 cm to 47.00-97.99 cm. In similar period, the average weight also changed from 285.33 gram to 309.00 gram. The length changes are apparently due to the process of spawning. Based on the observation, the estimation result shows that the speed of exploitation of hairtail population is yet to reach overfishing fisheries, suggested to fix the fishing season, adding the efforts and fishing zone, also data collection based on species.

Cilacap and surrounding waters is one of the potential fishing ground of banana prawn in south of Java sea. Abundance stock index of banana prawn in Cilacap and surrounding waters tend to decline in 2004-2010. It was apprehension for the banana prawn sustainability, when no appropriate management and utilization for this species. This research conducted in Cilacap and other shrimp fisheries centers in Cilacap District begin from January until November 2013. Data collected through a survey and interview methods. The method of analysis consists of : an analytical method by FiSAT II program, and surplus production models. Most of Banana prawn caught dominantly in the mid length 31 mm, 33 mm, and 35 mm, and generally immature. Value factor condition banana prawn females and males respectively ranged from 37.36-648.87 and 15.55-319.05. Growth rate (K) of banana prawn female was 1.10 per year and banana prawn male was 1.00 per year. The exploitation rate (E) of banana prawn female was 0.36 per year and banana prawn male was 0.56 per year. Total mortality rate (Z) of banana prawn female was 1.69 per year and banana prawn male was 2.46 per year. The pattern of recruitment showed two models in one year, with the peak season occur in the period of March-April and July-August.
