High total plate count (TPC) and the presence of Salmonella spp. in food products can cause health problems for consumers. De-boned milkfish products are popular with consumers in Palu City, Central Sulawesi, Indonesia, but there is a lack of data on their safety. Therefore, this study aimed to investigate TPC levels and detect contamination by Salmonella spp. in these products. Samples of fresh and processed milkfish were collected from two de-boned milkfish processing sites: the Technical Implementation Unit for the Application of Fishery Product Quality Control (TIU-AQFP) and the Melona Micro, Small and Medium Enterprise (MSME) Group in Palu City. Microbiological assays included counting the number of bacterial colonies (TPC) as well as the isolation and identification of Salmonella spp. through biochemical tests. The study applied a completely randomized factorial design with three replicates per site and per product (12 experimental units). De-boning had a significant (P0.05) effect on TPC (1.26×103 to 2.20×103 CFU/g for de-boned milkfish compared to 4.28×103 to 2.94×104 CFU/g for fresh unprocessed milkfish). However, the types of bacteria identified in fresh and de-boned milkfish, including Klebsiella, Enterobacter and Citrobacter, were present at non-pathogenic levels. No Salmonella spp. contamination was found in the test samples. These results indicate that de-boned milkfish products from the TIU-AQFP and Melona MSME Group in Palu City are safe and suitable for human consumption.Keywords:Bone-free milkfishBacterial contaminationPathogen assayFish processingFood safety

Penelitian bertujuan untuk mendapatkan dosis optimum ekstrak daun senggani dalam menghasilkan persentase jantan tertinggi pada ikan nila (Oreochromis niloticus). Penelitian didesain menggunakan rancangan acak lengkap yang teridiri dari 5 perlakuan dan 4 ulangan. Perlakuan yang diujikan yakni dosis ekstrak daun senggani; 0 (A/kontrol); 20 (B); 40 (C); 60 (D); 80 ppm (E). Larva ikan nila umur 7 hari direndam dalam air yang berisi ekstrak daun senggani sesuai dosis perlakuan selama 4 jam. Pasca perendaman, larva ikan nila dipelihara selama 60 hari. Pakan berupa cacing sutera diberikan selama 30 hari pertama dan selebihnya diberi pellet. Frekuensi pemberian pakan sebanyak 3 kali sehari (pukul 07.30-08.00, 12.30-13.00, dan 17.30-18.00 Wita). Hasil penelitian menunjukkan persentase kelamin jantan (KJ) pada perlakuan A, B, C, D, dan E secara berurut masing-masing sebesar 45%, 65%, 72%, 77,5%, dan 80%. Laju pertumbuhan harian (LPH) dan kelangsungan hidup (KH) untuk semua perlakuan berkisar antara 7,28-7,58 %/hari dan 85-95%. Hasil analisis menunjukkan persentase KJ ikan nila tertinggi terdapat pada perlakuan 80 ppm yakni sebesar 80%. LPH dan KH tidak berbeda secara signifikan antar semua perlakuan (P>0,05). Kesimpulan, ekstrak daun senggani (M. candidum) dengan dosis 80 ppm menghasilkan persentase jantan tertinggi (80%) pada ikan nila.

The Banggai cardinalfish Pterapogon kauderni is the Indonesian national marine ornamental fish mascot, and an object of national and international conservation concern. The endemic population of this species is limited to the Banggai Archipelago in Central Sulawesi, Indonesia and a few nearby islands in North Maluku. In addition, introduced populations have become established, mainly along ornamental fish trade routes. The National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) calls for monitoring and management of all P. kauderni populations. A survey of the Luwuk introduced P. kauderni population was carried out in October 2021. Data were collected at three sites with established P. kauderni populations: the ferry harbour, public harbour (Teluk Lalong) and a recreational area on the nearby coast (Kilo 5). P. kauderni were recorded by microhabitat association and size class (recruits, juveniles, adults). Data collected were compared with data from previous surveys where available. With the exception of one group in a sea anemone at Kilo 5, all P. kauderni were associated with Diadema sea urchins (D. setosum at all sites; D. savignyi at Kilo 5). At Kilo 5 P. kauderni the population structure indicates the possible capture of market-sized juveniles. Overall abundance was also lower compared to the polluted but unfished harbours. The proportion of recruits was significantly negatively correlated with the ratio of adult P. kauderni to Diadema urchins. The results will inform regional legislation currently in preparation to support sustainable management of P. kauderni populations, habitat and microhabitat in Central Sulawesi, as well as contributing to NAP-BCFC targets.Keywords:Banggai cardinalfishEndangered speciesDiademaMicrohabitat,MonitoringOrnamental fisheryLocal regulation

Salah satu faktor penting dalam kegiatan akuakultur, namun memiliki dana operasional termahal adalah pakan. Sebagai upaya akuakultur berkelanjutan dan jaminan harga pakan yang terjangkau adalah melalui pemanfaatan bahan baku yang melimpah dan tidak bernilai ekonomis. Kelapa sawit dikenal sebagai tanaman multiguna, seperti pelepah sawit yang sebelumnya diketahui sebagai limbah perkebunan kelapa sawit jumlahnya melimpah dan tidak bernilai ekonomis. Bahan inovatif yang dapat dikembangkan menjadi olahan adalah tepung sebagai sumber nutrien bagi organisme budidaya termasuk pada ikan nila. Akan tetapi, bahan tersebut memiliki zat antinutrisi yang membutuhkan pengolahan lebih lanjut. Penelitian ini bertujuan untuk mendapatkan jenis probiotik yang sesuai sebagai bahan fermentasi dalam menurunkan kandungan zat antinutrisi tepung pelepah sawit yang diamati melalui respons pertumbuhan yang dihasilkan. Penelitian mengujikan jenis probiotik A (Effective Microorganisms/EM-4), B (Boster), C (Raja lele), dan D (Ragi tempe) masing-masing pada benih ikan nila. Setiap perlakuan diberi tiga kali ulangan. Benih ikan nila yang diberi pakan perlakuan berbahan baku tepung pelepah sawit yang difermenatsi dengan probiotik EM-4, Boster, Raja lele, dan ragi tempe menunjukkan respons pertumbuhan (laju pertumbuhan spesifik harian dan pertambahan bobot individu) masing-masing sebesar 6,01%; 5,87%; 7,71%; 3,75% dan 7,34g; 7,03g; 9,95g; 3,75g. Rasio konversi pakan dan kelangsungan hidup masing-masing sebesar 1,09; 1,11; 0,92; 2,11 dan 70%; 73,3%;80%; 50%. Hasil analisis menunjukkan respons pertumbuhan dan kelangsungan hidup lebih tinggi dan rasio konversi pakan lebih rendah (P<0,05) pada ikan hasil perlakuan pakan berbahan baku tepung pelepah sawit yang difermentasi dengan probiotik Raja lele. Fermentasi tepung pelepah sawit sebagai bahan baku pakan menggunakan probiotik Raja lele memberikan respons pertumbuhan tertinggi.

The Banggai cardinalfish (Pterapogon kauderni Koumans, 1933) is a conservation priority species in Indonesia. To date there has been no effort to rear Banggai cardinalfish on a commercial scale, so that fish are still mainly captured from the wild. Therefore, efforts are being made to develop ex-situ Banggai cardinalfish culture using different types of natural feed. This research aimed to determine the best type of natural feed to promote the growth and survival of juvenile Banggai cardinalfish. The research was conducted during December 2021-January 2022, at the Central Sulawesi Provincial Marine Affairs and Fisheries Service Hatchery, in Mamboro Village, Palu City. The study used 3 treatments with 6 replicates each: A (Artemia), B (Cullex), and C (Tubifex). The use of different natural feeds had a significant effect on net weight gain but did not have a significant effect on daily growth rate and net growth in length. Treatment B (Cullex) gave the highest net weight gain and daily growth rate of 0.08 ± 0.3 g and 0.25 ± 0.1 % respectively; treatment A (Artemia) gave the highest net growth in length of 0.5 ± 0.2; and survival rate was highest (100%) under treatment B (Cullex).

Nile tilapia (Oreochromis niloticus) is one of the freshwater fish commodities in Indonesia. In aquaculture, Nile tilapia often uncontrolled spawning, leading to inhibited growth, varied harvest sizes, and prolonged harvesting time to achieve the target production size of >250 g/fish. Application of sex reversal on larval stages (1-2 weeks old) and the sorting of Nile tilapia fingerlings (1-2 months old) are efforts that can be undertaken to address these issues. However, generally, the fish farming community in Tulo Rantea Village, Dolo District, Sigi Regency, Central Sulawesi Province, lacks a detailed understanding of the implementation of these technologies. The aim is to facilitate local community in applying the conveyed technology to contribute improvement of local economy. Simulation of the sex reversal method on larvae is conducted using a honey solution at a dosage of 10 mL/L of medium. Meanwhile, the sorting simulation employs a methylene blue solution. Implementation of these activities proceeds smoothly, and enthusiasm of community is notably high. In conclusion, the technology transfer, particularly in preventing uncontrolled spawning in Nile tilapia cultivation to expedite the harvest time, proves effective through simulation. This allows the community to easily understand and apply methods.
