Abstract

Fluctuating asymmetry of the bilateral meristic characteristic is one of the simple methods that can be used to determine the stability of an individual fish development. This study aims to provide quantitative information about the level of asymmetry of Nile tilapia (Oreochromis niloticus) in Dunia Air Independent Training Center Marine and Fisheries, Banyuwangi through bilateral meristic characteristic observation.  A total of 120 fish samples (5-7 cm) were measured in this study. Four bilateral meristic characters were calculated i.e. the number of soft pectoral fins, number of soft ventral fins, number of scales on the lateral line up and down. The results show that the highest value of the fluctuating asymmetry of magnitude (FAm) and fluctuating asymmetry of number (FAn) was obtained at the number of scales on the lateral line up those are 2.14 and 0.78, respectively. Meanwhile, the lowest FAm and FAn values obtained from the soft ventral fins which were 1.69 and 0.78, respectively. The sum of the total value of fluctuating asymmetry of each bilateral meristic characteristic was observed. The overall FAm value was 7.83 and the overall FAn value was 2.99.Keywords: fluctuating asymmetry, Nile tilapia, PMKP Dunia Air

Abstract

The aims of this study is to determine the number and distribution of the chromosomes of three Nile tilapia (Oreochromis niloticus) varieties as basic information in the process of identifying the characteristics of varieties in tilapia. This research was conducted in August-October 2016, at the Unair Banyuwangi PSDKU laboratory. The research procedures included rearing of test fish, immersion of test fish with colchicine solution and tissue preservation, preparation of preparations and staining, and observation. Based on the results of the study, it was found that each variety of tilapia (black, red, and white) showed a difference in the spread of chromosomes, while the number of chromosomes was the same, namely 44 pieces.

Abstract

Asymmetric fluctuations function as a measure of organ stability in pairs in an individual. This study aims to determine the value of asymmetric fluctuations in hybrid grouper hybrid fish from Situbondo and Bali. The study was conducted for 3 months, starting from July-September 2018. The grouper used in this study was 100 individuals from each region, with a size of 7-9 cm. Bilateral meristic characters measured include the pectoral fin, ventral fin and lateral line. The results showed that the ventral fin character of the grouper fish from Situbondo and Bali had a higher FA value of 0.6-0.7, while the lateral linea organ had a higher FAm value, 1.1 to 1.9. The FAgb value of the grouper originating from Situbondo has a high value compared to the grouper from Bali, which is 1.5-2.4.

Abstract

Fluctuating asymmetry of bilateral meristic characteristic is one of the simple methods that can be used to determine the stability of an individual fish development. This study aims to provide quantitative information about the level of asymmetry red tilapia (Oreochromis niloticus) in Genteng Fish Hatchery Center through bilateral meristic characteristic observation. The number of fish used in this study is 100 fish which have a measurement of 5-7 cm. Bilateral meristic characteristic observed is the number of soft pectoral fins, the number of soft pelvic fins, and the number of scales on the lateral line. The results show that the highest value of the fluctuating asymmetry magnitude (FAm) and fluctuating asymmetry number (FAn) are obtained at the number of scales on the lateral line those are 3.71 and 0.86. Furthermore, on soft pectoral fins, the FAm value obtained is 1.29 and the FAn value is 0.58. Meanwhile, the lowest FAm and FAn values obtained from the soft ventral fins which are 0.93 and 0.50. The overall FAm value is 5.93 and the overall FAn value is 1.94.

Abstract

Feed is the key to success in aquaculture, because it affects the resistance and development of larvae. There are two types of feed given to fish, namely artificial feed and natural feed. One type of natural feed that can be used as an enhancer for aquaculture feed needs is Tetraselmis sp.. So that practice is needed to learn, understand and practice directly the Tetraselmis sp. Natural feed culture techniques. laboratory scale. This research was held at the Brackish Water Aquaculture Center (BBPBAP) Jepara, Central Java for 46 days starting on December 17, 2018 until January 31, 2019. The culture technique consists of several stages including the preparation of tools and equipment, sterilization, fertilizer making, media preparation, calculation of inoculants, nutrition, seedling and maintenance. Based on observations for 16 days, Tetraselmis sp. has four growth phases consisting of adaptation, exponential, stationary and death phases. Tetraselmis sp. experienced the highest density on the tenth day with an average of 109.87 x 104 cells / ml. This shows that the growth of Tetraselmis sp. long enough than other species. After experiencing the exponential phase, Tetraselmis sp. experienced a stationary phase for 3 days and subsequently decreased density to reach 65.22 x 104 cells/ml on the sixteenth day.Keyword : Tetraselmis, Phytoplankton, Culture Technique

Abstract

Pesticides are pollutants that are found in rice fields and rivers. Pesticides that are often used by farmers in Indonesia in eradicating insects are organophosphate insecticides, where they can eradicate insects that are very toxic to fish due to strong neurotoxic substances that inhibit AchE (Acetylcholinesterase) activity. The research aims to examine the effect of organophosphate pesticides on hematology and histopathology of hematopoietic organs in silver rasbora fish. The research method used is an experimental method with a CRD. The parameters observed were hematology and histopathology hematopoietic organ (liver and kidney). The results of this study showed a hematological change in silver rasbora fish where there was a decrease in total erythrocytes (0,59±0,004) and hemoglobin (2,5±0,1) while total leukocytes increased (245,35±15,78). Also, there are differential changes in leukocytes, namely an increased in the number of monocytes (5±1) and neutrophils (24±3), but lymphocytes have decreased in number (72±1). The Histopathology of the fish liver also can found in this research, those damages that are found are erythrocyte infiltration, necrosis picnosis, and karyolysis. Histopathology of fish kidney also can found cloudy sweling, necrosis karyolysis and tubular necrosis.

Abstract

Panti asuhan merupakan suatu lembaga sosial untuk membentuk perkembangan anak-anak yang tidak memiliki keluarga atau tidak tinggal bersama keluarganya. Panti asuhan mempunyai tanggung jawab untuk memberikan pelayanan kesejahteraan sosial dan mental. Pada kenyataanya banyak panti asuhan yang masih terkendala terkait biaya operasional dalam melakukan pengembangan pembinaan anak-anak panti. Sistem akuaponik merupakan gabungan teknologi budi daya ikan dan tanaman dalam satu wadah.  Budidaya ikan lele dumbo dengan sistem akuaponik merupakan solusi alternatif dalam menunjang kemandirian panti asuhan. Tujuan yang  diharapkan  dari  kegiatan  ini  adalah adanya kegiatan usaha budidaya ikan di Panti Asuhan Yatim Budi Mulya Banyuwangi sehingga menjadikan kemandirian panti secara ekonomi semakin cepat terwujud. Fasilitas sistem akuaponik telah dibangun dan dihibahkan kepada mitra dan kemudian dilakukan kegiatan pengenalan sistem budidaya akuaponik terdiri dari cara pembuatan akuaponik dan komoditas yang dibudidayakan, sistem budidaya dan manajemen budidaya serta monitoring kegiatan budidaya. Metode sosialisasi dan diskusi dengan menggunakan daring platfom zoom. Evaluasi pelaksanaan program akuaponik dilakukan sebelum dan sesudah kegiatan. Data yang diperoleh kemudian disajikan dalam bentuk grafik serta dianalisis secara deskriptif. Kegiatan budidaya ikan lele dumbo sistem akuaponik dapat diaplikasikan pada lokasi mitra. Guna menunjang kemandirian panti asuhan,sehingga mampu mendapatkan penghasilan secara mandiri.
