Abstract

Overfishing, the use of unfriendly-environmental fishing gears, changes of environmental water conditions and diversity of habitats are threaten the continuity of Bujuk fish (Channa lucius) and generate the morphologycal diversity. Consequently, appropriate conservation efforts are needed to preserve the fish. The first phase of these efforts were done through morphological approach. The research was held in 2010 in Singkarak Lake West Sumatera Province, in floodplain, Pematang sub-district Lindung Mendahara Ulu Regency East Tanjung Jabung, Province of Jambi, and in floodplain Mentulik Regency Kampar Kiri Hilir Riau Province. The aims of the research were to analyze the morphological characteristic of the fish with Principal Component Analysis (PCA) and to determine the range of similarity between populations of the fish. Determination of the location of fish sampling was conducted by proposive sampling in which there were 30 samples for every research location. The measurement of the specimen was done by digital calipers on the left of the body, at 4 meristic characters and 19 morphometric characters. The data obtained were analyzed by One Way ANOVA and principal component analysis using Statistical software version 13. The results showed that based on the analysis of morphological characteristics of bujuk fish, populations that exist in Lake Singkarak were different from those of Pematang Lindung floodplain sub-district Mendahara Ulu Regency East Tanjung Jabung Jambi Province and Mentulik Regency floodplain Kampar Kiri Hilir Province Riau. The meristic difference was on the number of scales along the lateral line with a value of 0.783. While the main difference on morphometric characters were the snout length with a value of 0.848, and length of upper jaw with a value of 0.847. Thus, the study showed that the fish was isolated geographically into two groups, which were Jambi-Riau population and Singkarak Lake population.

Abstract

The purpose of the research was to find out the countent of nutrition of Ara (Ficus racemosa L) wich covers : thelevel of protein, fat, water, ash, fibrous part of the fruit, calcium, phosphor, vitamine C and E as well as amino acidwhich are very useful for enrichment of fish diets. The sample of Ara fruit were collected directly in the field. Therewere two types of processing Ara fruits used in this research, namely (1) cutting the fruits into thin layer and madeit into; (2) separating the fuit from the seed, dried, and made it into flour. The level of protein, fat, fibrous part of thefruit, water, and ash was analyzed by using proximate analysis, while the level of calcium was analyzed by usingAAS methods. The level of phosphor was measured by using spectrophotometer, the level of vitamine C and E wasanalyzed by using HPLC and amino acid by gas chromatography (CG). The study found that the flesh flour of Arafruit contained protein (10,63%), fat (8,66%), water (7,08 %), ash (11,57%), fibrous part of the fruit (16,15%), calcium514,88 mg/100 g), phosphor (418,29 mg/100 g), vitamine C (475,38 mg/100 g), and amino acid (3,013 %) higher thanAra flour with protein (8,98 %), fat (6,57%), water (10,26%), ash (18,23%), fibrous part of the fruit (20,31%), calcium(0,039 mg/100g), phosphor (0,002 mg/100g), vitamin C 25,48 mg/100 g ), and amino acid (1,24%). It can be concludedthat the Ara flour can be used as on of the ingredients for fish diets especially as the source of vitamine C, calciumand phosphor to incrase reproduction ability and growth.

Abstract

The purpose of study is to know nutrition of jelawat eggs, compriseprorein, fat, calcium, phospore, essential amino acid, essential fatty acid, vitamineC and vitamine E. Method applied to get the purpose is take jelawat eggshave TKG IV ( gonad stages mature) on brood stock with 4kg, and weight wet ofgonad 600 gram at Maninjau Lake. Eggs are dried and floured. The study usesproximate-analysis to get quantity of protein, fat, calcium and phospore andHPLC methode to get the essential amino acid, fatty acid and vitamine C and E.The result show that fish jelawat floured have within it nutrition protein61,33 %, fat, 11,90 %, water content 4,88 %, ashes content 8,26 %. Quantityamino acid 52,69 %, linoleat fatty acid 7,71.%, linolenat fatty acid 0,05 %,vitamine C 0,240 % and vitamine E 0,310 %.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan ekstrak gambir terhadap kehidupan dan pertumbuhan ikan lele yang terinfeksi bakteri Aeromonas hydrophila. Ikan yang digunakan adalah 1.500 benih lele mutiara umur 35 hari dan panjang 3-5 cm. Ikan disimpan selama 22 hari dalam akuarium berukuran 80x40x35 cm. Frekuensi pemberian pakan 3 kali sehari diberikan pada pukul 08.00, 12.00, dan 17.00 WIB dengan jumlah pakan 5% dari biomassa dengan teknik pemberian secara at satiation. Metode penelitian eksperimental Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 ulangan. Dosis Perlakuan A. Pakan buatan tanpa penambahan dosis ekstrak gambir B, C, D dan E merupakan pakan buatan dengan penambahan dosis ekstrak gambir 25g, 50g, 75g dan 100g. Variabel yang diamati meliputi Survival Rate (SR), Food Conversion Ratio (FCR), pertambahan bobot mutlak, Specific Growth Rate (SGR), Thermal Growth Coefficient (TGC) dan Canibalism Rate (CR). Hasil penelitian menunjukkan bahwa penambahan ekstrak gambir dalam pakan berpengaruh nyata (P<0,05) terhadap SR, FCR, pertambahan bobot mutlak, SGR, TGC dan CR. Perlakuan terbaik adalah pada dosis 75g/kg pakan dengan nilai SR tertinggi (70,46%), FCR (1,1), pertambahan bobot mutlak (1,63 g), SGR (7,41%), TGC (6,72) dan CR (5,67). Disimpulkan bahwa penambahan ekstrak gambir dalam pakan mampu menekan tingkat kematian ikan yang disebabkan oleh bakteri Aeromonas hydrophila, meningkatkan pertumbuhan dan menekan jumlah kanibalisme.
