This paper (in Indonesian) was presented at the Simposium Nasional Pengelolaan Perikanan Ikan Karang Berkelanjutan Indonesia, Bali 25-26 Novermber 2015, a national conference on sustainaable reef fisheries. The paper is published in the Proceedings (pp. 317-334), the full version (> 100 MB) is available at http://bit.ly/ProsidingSimnasIkanKarang. The paper discusses the potential and suggests options for sustainable management of the Banggai cardinalfish (Pterapogon kauderni). This small shallow-water fish, popular in the marine aquarium trade, has an extremely restrictied native (endemic) distribution and is listed as Endangered in the IUCN Red List. The Banggai cardinalfish is a national priority species for marine and fisheries conservation, a CTI fisheries management target (sustainable ornamental fishery), and (now twice, at the time once) proposed for listing under CITES Appendix II. The paper includes key results from an EAFM (Ecosystems Approach to Fisheries Management) evaluation in 2014 (supported by WWF Indonesia), reviews several initiatives from 2004-2015. The conclusions stress the importance of a holistic approach, in particular attention to habitat and microhabitat conservation and stakeholder engagement.

The climbing perch, Anabas testudineus Bloch 1972, is a valued freshwater fish with a wide distribution in South and Southeast Asia. This study examined the meristic counts and length-weight relation of climbing perch from Sigi District, Central Sulawesi, Indonesia, close to the eastern extremity of the species distribution. Specimens collected from wetlands in Sigi District were weighed and measured (total length) to derive length–weight relation (n = 265) and meristic counts (n = 140). Length (L, in mm) – weight (W, in g) relation (W = a·Lb) parameter b = 2.98 overall; for females b = 3.06 while for males b = 2.88. Maximum length Lmax was 163 mm. The meristic formula using median values was D, XVII+8; A, X+9; P, 13; V, I+5; C, 16. Mean scale counts for both male and female climbing perch were: longitudinal 31 and vertical 15. There was no significant between-sex difference in meristic characters. Although the average growth pattern was isometric, males exhibited a slight allometric negative tendency. Low maximum size is consonant with other indications of a population under pressure, reinforcing the need for sustainable, holistic wetland management. In the context of domestication, high variability in meristic characters may indicate high genetic diversity and/or plasticity, which could provide scope for selective breeding.

The research was conducted to study the effect of salinity on the growth of Banggai Cardinalfish Pterapogon kauderni. The research was set up in completely randomized design with different salinity as the main variable, i.e. 27, 29, 31, 33 and 35 ppt with 4 replications. The result showed that the lowest salinity (27 ppt) resulted in the highest fish growth (1.625 g).Keywords: Growth, salinity, Banggai Cardinalfish. ABSTRAKPenelitian telah dilakukan untuk mengetahui pengaruh salinitas terhadap pertumbuhan ikan kardinal banggai Pterapogon kauderni yang dipelihara dalam akuarium. Penelitian menggunakan Rancangan Acak Lengkap dengan 5 perlakuan salinitas, yaitu 27, 29, 31, 33 dan 35 ppt, masing-masing 4 kali ulangan. Hasil penelitian menunjukkan bahwa pertumbuhan berat mutlak (1,625 g) tertinggi diperoleh pada salinitas 27 ppt.Kata kunci: Pertumbuhan, salinitas, Kardinal Banggai.

Penelitian ini bertujuan untuk mengetahui pemberian pakan berbahan baku tepung maggot (Hermetia illucens) dengan feeding rate berbeda terhadap pertumbuhan dan kelangsungan hidup ikan nila (Oreochromis niloticus). Organisme uji yang digunakan adalah benih ikan nila (O. nilaticus) dengan bobot 1,53 - 2,03 g sebanyak 200 ekor. Benih ikan nila diperoleh dari Pembudidaya di Desa Potoya, Kecamatan Dolo, Kabupaten Sigi, Sulawesi Tengah. Penelitian ini didesain menggunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dan 5 ulangan sehingga terdapat 20 unit percobaan. Perlakuan dalam penelitian ini yakni pemberian pakan dengan feeding rate berbeda yaitu: A (4% dari biomassa ikan); B (5% dari biomassa ikan); C (6% dari biomassa ikan); dan D (7% dari biomassa ikan). Hasil penelitian menunjukkan bahwa pemberian pakan berbahan baku tepung maggot dengan feeding rate berbeda berpengaruh nyata terhadap pertumbuhan bobot mutlak ikan nila. Pertumbuhan bobot dan kelangsungan hidup ikan nila tertinggi (p<0,05) diperoleh pada perlakuan feeding rate 7%.
