UJI COBA PENANGKAPAN MENGGUNAKAN AYUNAN DENGAN BENTUK YANG BERBEDA (EXPERIMENTAL FISHING USING AYUNAN WITH DIFFERENT FORMS)
Get PDFAyunan is the trap most widely used by public Sungai Batang Village, inaddition to the unique shape of this tool also has an extensive capacity toaccommodate good catches of shrimp and fish species. In addition to the village ofSungai Batang, at the Hulu Sungai region there is also the ayunan that looks differentfrom contained in Sungai Batang Village.This study aims to (1) know the difference between shrimp of catch amorayunan and box ayunan, and (2) to determine the catch other than shrimp. Theresults of research, treatment A (amor ayunan) shrimp catches as many as 1464 ,with a total weight of 9100 grams. Treatment B (box ayunan), shrimp catches asmany as 1443 , with a total weight of 7730 grams. Type of main haul shrimp(Macrobrachium rosenbergii de Man) and Freshwater Shrimp (Palaemon sp), with bycatches are Lundu (Mystus gulio) with a total of 18 and total weight of 215 grams,sapu-sapu (Hypostomus plecostomus ) 2 , weighing a total of 560 grams, Puyau(Osteochilus hasselti) 3 , weighing a total of 35 grams, telan (Macrognathusaculeatus) 2 , weighing 810 grams.Bamboo and rattan as materials to make the ayunan has a weaknessbecause odor (smell) is not good (bangai) and therefore contributes to the catch. Toovercome this weakness it is advisable to replace the wire with the basic material

PENGARUH PERBEDAAN TINGKAT PROTEIN DAN RASIO PROTEIN PAKAN TERHADAP PERTUMBUHAN IKAN SEPAT (Trichogaster pectoralis)
Get PDFTujuan penelitian ini untuk mengetahui tingkat protein dan energi pakanterbaik pada ikan sepat. Manfaat penelitian ini untuk dapat dijadikan informasi dasar mengenai tingkat protein dan energi yang sesuai bagi kebutuhan konsumsi pakan danpertumbuhan benih ikan sepat. Ikan uji yang digunakan ikan sepat (Trichogasterpectoralis) dengan bobot individu berkisar antara 5±2 gram dan panjang baku berkisar5±3 cm. Penelitian dilakukan secara eksperimen, menggunakan Rancangan AcakLengkap (RAL) dengan 6 macam perlakuan dan masing-masing diulang sebanyak 3kali. Perlakuan yang diberikan terdiri atas tingkat energi protein yang berbeda, yaitu perlakuan A (2800 kkal/35%), perlakuan B (3150 kkal/35%), perlakuan C (3150kkal/40%), perlakuan D (3600 kkal/ 40%), perlakuan E (3600 kkal/45%), dan perlakuan F (4050 kkal/45%). Parameter yang diamati meliputi pertumbuhan mutlak,laju pertumbuhan relatif, konversi pakan, efisiensi pakan, kelangsungan hidup, dankualitas air. Hasil penelitian menunjukkan bahwa pakan dengan tingkat protein 40%dan energi 3150 kkal/kg menghasilkan pertumbuhan mutlak, laju pertumbuhan relatif,konversi pakan, dan efisiensi pemberian pakan yang terbaik dibandingkan dengan perlakuan lainnya. Kelangsungan hidup ikan sepat berkisar antar 96,67-100%. Kualitas air (suhu, pH, DO, NH3, dan CO2) pada tiap perlakuan masih memenuhi standar untuk kehidupan ikan sepat

Get PDFDecreasing area of coastal swamp ecosystem causing stress to aquatic biota whichliving in those habitat, and give impact to fishermen’s prosperity level. Study of coastal swamp’s condition really important, with aim as consideration to decide policies that needed to reach environmental balancing and sustainibility of exploitation. Study was done to both primary and secundary data, which include tabulative, graphical, qualitative and quantitative/statistics and computative, both description and inferential, and so spatial analysis for reach locally information of mangrove area’s degradation, and temporal information of comparation with secondary data. Condition of ecosystem of coastal swamp in Jorong subdistrict, which representated by condition of ecosystem of mangrove showing damaged to really damaged condition. Rate of decreasing of mangrove areas in Jorong subdistrict reach of 614,49 ha, or average rate of areas decreasing were 38,41 ha/year. Factors that caused damaged/degradation process of coastal swamp in Jorong subdistrict, Tanah Laut Regency dominated by wave activities and area’s converted
PENAMBAHAN EKSTRAK KEPALA UDANG GALAH (Macrobrachium rosenbergii de man) UNTUK MENINGKATKAN KANDUNGAN PROTEIN PADA PRODUK OLAHAN STICK
Get PDFThis research aims to obtain an exact comparison between the volume of water and the weight of the giant freshwater prawn head (Macrobrachium rosenbergii de man) so as to increase the protein content in the processed products of sticks. The design used in the research was Completely Randomized Design (RAL) with 1: 1, 1: 2 treatment and without the addition of shrimp head extract (control). The parameters observed were organoleptic test, protein content, and water content. The result of this research showed that the extract of shrimp head with ratio 1: 1 resulted stick protein product 12,67%, while the treatment of prawns extract of prawn with ratio 1: 2 protein content was 13,24% and treatment without giving of shrimp head extract pole protein content only produce stick products with a protein content of 6, 21%. The addition extract of giant freshwater prawn head also yields a preferred flavor of the panelists compared to the treatment without the addition of a giant freshwter prawns head extract

INTERVENSI FOLICLE STIMULATING HORMONE (FSH) DALAM PROSES REMATURASI INDUK IKAN GABUS HARUAN Channa Striata Blkr DIDALAM WADAH BUDIDAYA
Get PDFSnakehead and other fish species in waters of the swamp doing spawning at the beginning or in the middle of the rainy season. Gonadal maturation process so as to returntime is limited. Aquaculture development is highly dependent on the availability of seeds that meet the timeliness, quality and quantity. The seeds can be produced continuously if supported by the availability of mature broodstock with good quality eggs. Some research about the role of hormones and or the use of stimulants to the success in support of gonad development and spawning, such as; Siam Jambal fish, Pangasius hypophthalmus (Ernawati 1999), Catfish, Clarias batrachus (Zairin et al. 2001), and catfish, Hemibagrusnemurus (Supriyadi 2005). By because they were with potential to take advantage of folicle Stimulating Hormone (FSH) that serves as the control at the start of the reproductive cycle up to ovulation and spermiasi in fish. The aim of this study was to determine the effect ofthe injection folicle Stimulating Hormone (FSH) in the parent rematurisasi catfish. Results from the start 17007-52327 item, 0,63-1,07 mm egg diameter, IGS range of 4, 13 to8.50%, and ranged from 0.86 2.4% IHS. Based on the results of the study injection folicle Stimulating Hormone (FSH) capable shorten rematurasi processing time
