Abstract

Konsumsi protein hewani masyarakat yang rendah, perlu ditingkatkan dengan menyediakan sumber protein yang berkualitas dan harga terjangkau. Ikan lele, dengan budidaya sistem intensif, dapat menjawab 2 tentangan tersebut, sumber protein berkualitas dan murah. Budidaya sistem bioflok memungkinkan terjadinya efisiensi penggunaan pakan sekaligus menaikan padat tebar ikan, sehingga cocok dilakukan di perkotaan dengan keterbatasan lahan. Budidaya sistem bioflok dilakukan dengan menumbuhkan mikroba yang akan mengurai amonnia hasil feses dan sisa pakan yang kemudian berguna sebagai sumber pakan alami bagi ikan. Analisa usaha lele sistem bioflok apabila dilakukan selama 10 periode dengan padat tebar pertama sebanyak 500 ekor per m3 kemudian kenaikan padat tebar sebesar 20% tiap periode selama 10 periode pemeliharaan akan menghasilkan keuntungan bersih sebesar Rp. 12.405.000 (pembulatan) dengan modal awal sebesar Rp.5.650.000.

Abstract

ABSTRACTAs a common properti, fisheries management in swamps need to be made to provides economic benefits for the parties on the one side (especially the community), and the sustainability of the ecosystem itself on the other side. Current conditions need to be obtained to formulate swamp resource management in a sustainable manner by reducing fishing activities with aquaculture activities. Aquaculture, besides providing greater income, can also control fishing activities and reduce pressure on the swamp ecosystem. The study was conducted in Rawa Deling, Deling Village, Pangkalan Lampam Sub-District, OKI District. Water quality measurements are carried out for 5 months, from March 2018 to July 2018 in 4 stations with differences depth and vegetation. Water quality analysis is carried out to get an overview of the swamp condition. Water quality data will determine the feasibility and treatment needed for aquaculture. The results of water quality measurements showed that temperature parameter values ranging from 28.1 - 32.2 oC, depths of 0.7 - 5 m, brightness of 20 - 50 cm, TDS 17 - 35 mgL-1, pH 4.1 - 5, DO 1 , 7 - 4.1 mgL-1, phosphate <0.060 - <0.090 mgL-1, total nitrogen 12.50 - 38.90 mgL-1, ammonia 0.68 - 0.93 mgL-1. Measuring water quality shows the potential for deling swamps to be developed in an effort to increase fish stocks and aquaculture activities.Keywords : lebak lebung swamps, sustainable fisheries management, swamp water quality

Abstract

Pemanfaatan Keramba Jaring Apung (KJA) pada perairan merupakan salah satu teknik akuakultur yang dapat dijadikan sebagai sumber perekonomian dan pemenuhan akan ikan. Lokasi budidaya ikan harus sesuai agar pengelolaan budidaya ikan dapat berjalan dengan maksimal. Penelitian bertujuan untuk mengetahui kesesuaian lokasi budidaya ikan menggunakan KJA dengan metode skoring atau penilaian. Lokasi pengamatan berada di Kabupaten Banyuasin yang terdiri dari Sungai Komering dan anak Sungai Komering (Sungai Rok Kemang, Sungai Aluran dan Sungai Pulau Tigo). Lokasi pengamatan ditentukan dengan metode purposive random sampling berdasarkan spesifikasi kondisi lokasi sungai. Pengamatan dilakukan pada bulan September, Oktober dan November tahun 2019. Sampel air diambil setiap bulan dan dianalisis secara insitu untuk suhu, kecerahan, kedalaman, kecepatan arus, pH, dan oksigen terlarut. Sedangkan untuk fosfat dan amonia dianalisis secara eksitu di laboratorium kimia perairan BRPPU Palembang. Hasil skoring atau penilaian di keempat lokasi, hanya Sungai Komering yang berpotensial untuk lokasi budidaya ikan (sesuai) tetapi kualitas perairan perlu dimonitor secara berkala terutama pada oksigen terlarut dan fosfat. Sungai Rok Kemang, Sungai Aluran dan Sungai Pulau Tigo tidak dapat dijadikan sebagai lokasi kegiatan budidaya ikan karena kedalaman, kecepatan arus, oksigen terlarut dan fosfat tidak mendukung.

Abstract

The research was conducted to determine the abundance, diversity, uniformity, and dominance of plankton in fish stomachs and waters that are expected to provide information about water productivity. The research was carried out in a tributary of the Ogan River, Indralaya District, Ogan Ilir Regency, South Sumatra at three stations, namely Indralaya Mulya Village, Tanjung Seteko Village and Muara Penimbung Village. The method used field surveys and location determination using purposive sampling with fish stomach contents, water samples for plankton observations, and water quality parameters. Fish sampling was carried out six times in 3 months, and water samples for plankton observations were one time per month, from April to June 2018. Plankton is found in fish stomachs and waters with a total abundance of 35.6 - 448.12 ind/l plankton consisting of 8 divisions with 11 classes. The plankton diversity index has moderate diversity and moderate community stability with a value between 1.11 - 1.45. The uniformity index of plankton in the fish stomach showed small uniformity of plankton (0.41-0.67), while in the waters, at station three and station 1 in April, the uniformity was high (E values 0.72 and E 0.93). The value of the plankton dominance index is in the range of 0.27-0.37. No species dominate other species or D = 0 (0.5), with moderately polluted water quality

Abstract

Research on the diversity of fish fauna has been widely carried out, especially in Indonesia, even in some areas has decreased, especially in rivers due to many factors. The Ogan River that flows through Ogan Ilir Regency is a multipurpose river for the community, not only for daily needs, transportation, aquaculture activities, and capture fisheries. Currently, information on fish fauna in the Ogan River in Ogan Ilir Regency has not been verified and has not been published in detail. The study aims to determine the types of fish caught, diversity index, uniformity index, abundance index, and dominance index. The research was conducted in the Ogan River, South Pemulutan Subdistrict, Ogan Ilir Regency with a survey method that determines the station point by purposive sampling and produces three stations with different characteristics. Sampling of fish was done 8 times for three months using a gill net. The results showed that in the Ogan River 24 species of fish were found with a total catch of 276 fish classified into 14 families, namely dukang fish, dukang yellow fish, long whiskers catfish, asian redtail catfish, marble goby, milkfish, duskyfin glassy perchlet, striped snakehead, nile tilapia, long tongue sole, silver barb, tinfoil barb, beardless barb, black sharkminnow, bonylip barb, umbut fish, sleepy goby, kissing gourami, amazon sailfin catfish, giant prawn, giant gourami, pangasius juaro, malayan leaffish, and lais fish. All stations show a moderate diversity index value of 1.72-2.842, the uniformity index value shows evenly distributed at all stations, namely 0.898 - 1.816, the abundance index value is 1 which indicates less abundant at all stations and the dominance index shows a low value that ranges from 0.068-0.094 or no dominating species.

Abstract

Belanti village used to be land before the entry of the palm oil company, which caused the canalization to form a lake or swamp. The company's canalization blocked the flow of a natural river in Ulak Pati, Pampangan sub-district, preventing water from flowing and causing it to pool in what was once open land. The result of this canalization caused changes to the ecosystem in the village of Rawa Belanti, which had an impact on the growth factors of aquatic organisms that formed along with the formation of the lake/swamp. This study focuses on collecting data and information about the growth of cork fish that are found in many communities in rawa belanti through the sampling method. The study was conducted for 4 months with sampling intervals every 10 days. Calculation of length-weight and condition factor used all cork fish caught during the sampling.The growth factors assessed were the correlation between length and weight, and the condition factor of the gourami fish caught in the swamp. Based on the results of the study, the correlation of length and weight growth is negative allometric, which means that weight growth is slower than the growth of fish length. Assessment of the condition factor of cork fish shows an average value of 1, which means that the fish is in good body condition. Water quality assessment was also conducted in order to support growth data.

Abstract

Environmental factors play an important role in the growth and survival of fish, both directly and indirectly. This role is not limited to determining the success of fish growth in terms of length and weight; fish behavior, feeding patterns, and metabolism are also affected. Photoperiod itself is defined as the length of time of light and dark exposure. This study aims to evaluate the effect of photoperiodism on the growth rate and physiological response of red tilapia (Oreochromis niloticus). The study was conducted in Gandus District, Palembang City. Data and analysis were performed using a completely randomized design (CRD) with several parameters such as growth rate, weight gain, survival rate, and behavior of red tilapia observed qualitatively in response to treatment with varying light exposure times. The treatments given were 3 variations of light and dark exposure and 5 repetitions with variations P1: 20 hours of light: 4 hours of dark (20T; 4G) P2: 16 hours of light: 8 hours of dark (16T; 8G), and P3: 12 hours light : 12 hours dark (12T; 12G). The analysis results showed that red tilapia had a positive growth response, characterized by an increase in fish length and weight, caused by increased metabolism due to an increase in feed consumption rate. Fish behavior changed compared to the control group due to physiological stress caused by prolonged exposure to light.
