Abstract

Plankton is an important organism forming the food chain and material cycle in the waters. Plankton is divided into two groups, namely the group of phytoplankton (plant plankton) and zooplankton (animal plankton). These two organisms has an important role, namely as producers and consumers in one ecosystem (Aini et al., 2018). It has important role in a waters as a primary producer and bioindicator of the fertility level of a waters. The results of calculating the average value of plankton abundance in weeks 1, 2, 3, and 4 of phytoplankton are 35,523 cells/l and zooplankton are 16,327 ind/l, plankton diversity index values in weeks 1, 2, 3, and 4 of phytoplankton are 1.967 cells/l and zooplankton are 1.091 ind/l. The results of calculations using the STORET method in week 1 with a total score (-10), week 2 with a total score (-1), week 3 with a total score (0), and week 4 with a total score ( -12). The difference in these values is influenced by several factors and differences in the values of water quality measured during the study.

Abstract

Climbing perch enlargement activities are constrained by available fry, due to insufficient production. One of the unknown aquaculture factors is the best water level that can be used in spawning activities for climbing perch. The purpose of the study was to determine the effect of water level manipulation on the spawning results of climbing perch carried out naturally. The study used 3 treatments, namely water levels of 40 cm, 50 cm, and 60 cm and each treatment was repeated 4 times, while the parameters observed included fecundity, egg diameter, fertilization rete, hatching rate, survival rate, and water quality. The results showed that fecundity, egg diameter, fertilization rate, the highest hatching rate were obtained at treatment B of 26419.50 eggs, 0.63 mm, 59.50%, and 41.25%, respectively, while the highest survival rate was obtained in treatment A, which was 71.00%. Water quality during the study was still at the tolerance limit that supports the spawning of climbing perch, namely temperatures between 25.2 – 26.2oC, pH between 7.05 – 7.34, and DO between 3.77 – 4.21 mg / L. Based on diversity analysis (ANOVA) it shows that Fhitung < Ftabel is stated to be no real difference between all treatments given (receive H0) and the results of regression tests show that a water level of 45 cm is optimal for natural spawning of climbing perch Kegiatan pembesaran ikan papuyu terkendala dengan benih yang tersedia, karena produksinya yang tidak mencukupi. Salah satu faktor budidaya perairan yang belum diketahui adalah ketinggian air yang terbaik yang dapat digunakan dalam kegiatan pemijahan ikan papuyu. Tujuan penelitian untuk mengetahui pengaruh manipulasi ketinggian air terhadap hasil pemijahan ikan papuyu yang dilakukan secara alamiah. Penelitian menggunakan 3 perlakuan, yakni ketinggian air 40 cm, 50 cm, dan 60 cm serta masing-masing perlakuan diulang sebanyak 4 kali, sedangkan parameter yang diamati meliputi fekunditas, diameter telur, derajat pembuahan, derajat penetasan, survival rate, dan kualitas air. Hasil penelitian menunjukkan bahwa fekunditas, diameter telur, derajat pembuahan, derajat penetasan tertinggi diperoleh pada perlakuan B masing-masing 26419,50 butir, 0,63 mm, 59,50%, dan 41,25%, sedangkan survival rate tertinggi diperoleh pada perlakuan A, yakni 71,00%. Kualitas air selama penelitian masih berada pada batas toleransi yang menunjang pemijahan ikan papuyu yaitu suhu antara 25,2 – 26,20C, pH antara 7,05 – 7,34, dan DO antara 3,77 – 4,21 mg/L. Berdasarkan analisis keragaman (ANOVA) menunjukan bahwa Fhitung < Ftabel dinyatakan tidak berbeda nyata antara semua perlakuan yang diberikan (terima H0) dan hasil uji regresi menunjukkan bahwa ketinggian air 45 cm adalah optimal untuk pemijahan ikan papuyu secara alamiah.

Abstract

Penelitian ini bertujuan yaitu mempelajari ketersediaan belut (Monopterus albus zuieuw) yang dijual pada 5 (lima) pasar di wilayah Kotamadya Banjarbaru dan mempelajari tingkat kesegaran belut pada nelayan dan penjual di 5 (lima) pasar Kotamadya Banjarbaru. Pasar di wilayah Banjarbaru sebagai salah satu tempat penjualan belut memperoleh sumbernya dari beragam pelosok baik di wilayah Kotamadya Banjarbaru maupun sekitarnya seperti Kabupaten Banjar. Pasar yang terletak pada 5 kecamatan di Banjarbaru tidak semua menjual belut sawah, karena khususnya di Kalimantan Selatan, belut merupakan hasil dari tangkapan alam bukan dari produksi budidaya. Data tentang ketersediaan belut di pasar, suplayer belut sampai dengan habitat dari belut perlu dikaji lebih dalam untuk memastikan bahwa belut yang dijual dan timgkat kesegaran sampai ke tangan konsumen, Hasil penelitian tentang Identifikasi Keamanan Pangan Belut Sawah (Monopterus albus Zuieuw) pada tingkat suplayer pasar Banjarbaru Kalimantan Selatan dapat diambil kesimpulan adalah penjualan belut di pasar pada wilayah Kodamadya Banjarbaru hanya tersedia pada pasar tertentu saja disebabkan tidak kesukaan terhadap belut yang didominasi oleh suku jawa; tingkat kesegaran belut umumnya masih bagus karena pada proses distribusi belut masih dalam kondisi sehat dan ditangani dengan baik, serta jarak tempuh antara daerah penangkapan dengan pasar paling jauh berkisar 25 – 34 km; dan pasar dengan jumlah penjualan belut terbanyak ada pada Pasar Bauntung di Kecamatan Banjarbaru Selatan, sedangkan terbanyak kedua adalah Pasar Ulin Raya.

Abstract

Penelitian ini mengidentifikasi Tempirai Kawat (Wire Stage Trap) di Perairan Desa Manarap Kabupaten Banjar yang meliputi keragaan tempirai kawat, komposisi dan proporsi, sebaran ukuran, dan produktivitas tempirai kawat. Metode yang digunakan adalah Purposive Sampling yaitu turun langsung kelapangan dengan menentukan kriteria-kriteria tertentu yang berkaitan dengan dinamika perikanan tempirai kawat. Analisis data yang digunakan adalah deskriptif. Tempirai yang digunakan di perairan Desa Manarap berbahan kawat, memiliki prinsip seperti perangkap (trap) yaitu mempermudah ikan masuk dan mempersulit ikan untuk keluar. Pengoperasian tempirai dilakukan di daerah rawa atau daerah sawah yang digenangi air dan terdapat vegetasi rawa contohnya seperti purun, kayu duri, eceng gondok dan teratai, dengan hasil tangkapan yang didominasi oleh ikan Sepat rawa (Trichopodus trichopterus), Sepat Siam (Trichogaster pectoralis) dan Nila (Oreochromis niloticus) This study identified the Wire Stage Trap in the waters of Manarap Village, Banjar Regency, which included the performance of the wire stages, the composition and proportions, size distribution, and the productivity of the wire stages. The method used is Purposive Sampling, which is a direct measurement of the field by determining certain criteria related to the dynamics of the wire tempirai fishery. Data analysis used is descriptive. Tempirai used in the waters of Manarap Village is made of wire, has a principle like a trap, which makes it easier for fish to enter and makes it difficult for fish to get out. Tempirai operations are carried out in swamp areas or paddy fields which are flooded with water and there are swamp vegetation, for example purun, thorn wood, water hyacinth and lotus, with catches dominated by swamp Sepat (Trichopodus trichopterus), Siamese Sepat (Trichogaster pectoralis) and Tilapia (Oreochromis niloticus)

Abstract

Penelitian ini bertujuan untuk menyeleksi dan mendapatkan antigen bakteri A.hydrophila strain lokal desa Sungai Batang dan Mandiangin Kalimantan Selatan yang bersifat imunogenik terhadap ikan lele dumbo. Antigen diinaktif menggunakan metode pemanasan (heat killed). Rancangan penelitian ini menggunakan Rancangan acak lengkap (RAL) dengan 6 perlakuan 3 ulangan yang meliputi perlakuan vaksinasi dengan antigen Aeromonas hydrophila strain P5.1 (A), strain AM01 (B), strain P1.1 (C), strain P3.1 (D), strain P4.1 (E) dan kontrol diinjeksi dengan PBS pH 7,0 (K). Antigen diinjeksi secara intramuscular sebanyak 0.1 ml (kepadatan bakteri 109 sel/ml) per ekor ikan uji (A,B,C,D,E). Hasil uji imunogenisitas antigen strain lokal P5.1 dan P1.1 bersifat lebih imunogenik terhadap lele dumbo dibandingkan dengan antigen lainnya berdasarkan kemampuannya meningkatkan antibodi pasca vaksinasi. Uji reaksi silang antigen A. hydrophila strain lokal AM01, P1.1 dan P5.1 mampu bereaksi silang dengan antigen lainnya. Antigen P1.1 mampu mengenali antigen lebih banyak dibandingkan P5.1 dan AM01, sehingga dapat direkomendasikan menjadi kandidat vaksin. This study aims to select and obtain antigens of the local strain A. hydrophila bacteria in Sungai Batang and Mandiangin villages, South Kalimantan, which are immunogenic to African catfish. Antigen is inactivated using the heating method (heat killed). The design of this study used a completely randomized design (CRD) with 6 treatments and 3 replications which included vaccination with the antigen Aeromonas hydrophila strain P5.1 (A), strain AM01 (B), strain P1.1 (C), strain P3.1 ( D), strain P4.1 (E) and control were injected with PBS pH 7.0 (K). Antigen was injected intramuscularly as much as 0.1 ml (bacterial density 109 cells/ml) per test fish (A, B, C, D, E). The results of the antigen immunogenicity test of local strains P5.1 and P1.1 were more immunogenic to African catfish compared to other antigens based on their ability to increase post-vaccination antibodies. Antigen cross-reaction test A. hydrophila local strains AM01, P1.1 and P5.1 are capable of cross-reacting with other antigens. P1.1 antigen is able to recognize more antigens than P5.1 and AM01, so it can be recommended as a vaccine candidate.
