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 was to know nutrient content of bilih fish Mystacoleucus padangenesis Blkr eggs meal to provide basic information for local material based fish feed development. The eggs were collected from fishermen. Parameters observed were proximate (protein, fat, moisture and ash), minerals (mangan and zinc), amino acid total, fatty acid, and vitamins (A, C and E) levels. The study showed that bilih fish eggs meal contained protein 22,44-59,90%, fat 12,67-18,09%, moisture 7,33-10,62%, ash 3,25-5,43%, amino acid total 14,57-27, 50%, fatty acid 0,24-0,53%, mangan 1,38-1,66 mg/100 g, zinc 22,39-24,73 mg/ 100 g, vitamin  A 188,95-218,44 mg/100 g, vitamin C  10,42-18,08  mg/100 g and  vitamin  E 8,64-10,39 mg/100 g samples.

Abstract

Pesatnya kegiatan penangkapan ikan bilih endemik di Danau Singkarak, sudah mengindikasikan penurunan populasi dan ukuran ikan tersebut. Oleh karena itu perlu dikelola agar dapat dimanfaatkan secara berkelanjutan. Salah satu alternatif pengelolaannya adalah berbasis kearifan lokal. Untuk itu diperlukan kebijakan pengelolaan ikan bilih berbasis kearifan lokal yang ada pada masyarakat nelayan. berdasarkan analisis SWOT dari sembilan strategi yang diperoleh, maka tiga strategi yang menjadi prioritas utama pengelolaan ikan bilih yaitu (1) pengelolaan penangkapan ikan berbasis kearifan lokal dengan nilai manfaat 0,518, (2) pengelolaan habitat ikan melalui pembuatan reservat secara ko-manajemen dengan nilai manfaat 0,280 dan (3) pengelolaan populasi ikan melalui pembenihan dan restoking dengan nilai manfaat 0,202. Peraturan yang lebih baikdalam pengelolaan dan pelestarian ikan bilih adalah dengan hukum adat dengan nilai manfaat 0,095.Overfishing of bilih fish endemic in Singkarak lake indicated a decrease in population and size of the fish. Therefore, it is necessary to do a management in order a sustainable. One of the alternative management is based on local wisdom.

The aim of the study is to investigate the reproduction aspects of Hampala sp and Osteochilus vittatus', wich is relationship between weight and lengths, maturity of the gonad, gonado somatic index (GSI) and fecundity. The research conducted from April to July 1997. The 49 sample of Hampala sp 21 sample was females and 28 sample was males . The length of Hampala sp female ranged 310 -410 mm, the weight ranged 320 - 753 gram. The male Hampala sp is length ranged 170 - 355 mm, the weight ranged 115 - 504 gram. The growth pattern of both is “isometric”. The first matured gonad was found at of 310 -330 mm length for female and 200.84-231.67 mm for male. Gonado Somatic Index for female ranged from 2.95 % - 7.74 % and for male ranged from 2.21 % - 3.07 %. The total ranged 88,442 -143,617 eggs. Nisbi fecundity was 4057 eggs/ gram of gonado weight. The 38 sample of Osteochilus vittatus 27 sample was female, the length ranged from 162 - 283 mm and weight ranged from 381.1 — 315.0 gram, 11 male at length ranged from 145 -226 mm and weight ranged 25.4 - 135.9 gram. The growth pattern for Osteochilus vittatus both is “isometric” .The first matured of the gonad was at of 182.18 - 202.35 mm length for female and at 145.00 - 165.25 mm for male.

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.
