Abstract

This research was aimed to study not only on gross morphologically but also on the histological structure of the Tetraodon lunaris digestive apparatus. The fish samples were obtained from a fisherman at the fish auction in Pelabuhan Ratu, from August 2005 until March 2006. The ratio between intestine and length/body length represented that this fish is carnivorous. The esophagus is short and the gastric forms a simple pouch with two of small diverticula. The intestine consists of a single loop. The esophagus and gastric mucous layer is covered with epithelial stratified cells. The intestine mucous layer has covered with a layer of columnar epithelial cells. The esophagus and gastric muscular layer consist of striated muscle. The sphincter pylorica and the intestine muscular layer consist of smooth muscle. The anus mucous layer consits of epithelial cuboid and it has the muscular layer of striated muscles. The liver has oval-shaped greenish vesica fellea with ductus choledochus emptied at the anterior part of intestine. The hepatocyt cells have a polygonal shape with lipid droplets in its. The exocrine glands of the pancreas tissue showed a set of acinar cells in the liver parencyhm, around portal vein, hepatic artery and biliary ductules.
PENGARUH ALKALINITAS TERHADAP KELANGSUNGAN HIDUP DAN PERTUMBUHAN IKAN LALAWAK Barbodes sp. [Effect of Alkalinity on the Survival Rate and Growth of Lalawak Fish, Barb odes sp.] Yulfiperius Yulfiperius; Mozes R. Toelihere; Ridwan Affandi; Djadja Subardja Sjafei

Abstract

This experiment was conducted to determine the effect of alkalinity on the survival rate and daily growth rate of Barbodes sp. The fishes were reared in 12 aquariums with four different alkalinity levels 48, 78, 108 and 138 ppm. Each aquarium filled with 10 fish at the average weight of 12.25 to 12.64 g attempt. The treatment lasted for 75 days. During the experiment, the fish were given commercial diet (pellet) with the dose of 5% of biomass weight at the frequency of three times a day. Result of the experiment showed that the survival rate for all treatments was 100%, while the alkalinity which suitable for daily growth rate of the fish was 80 ppm C’aCOr 
PENGARUH PEMBERIAN SELULOSA DALAM PAKAN TERHADAP KONDISI BIOLOGIS BENIH IKAN GURAMI (Osphronemm gourami Lac) [Effect of sellulose in dietary on the biological condition of giant gouramy fry (Osphronemus gourami Lac)] Zulfa Yandes; Ridwan Affandi; Ing Mokoginta

Abstract

An experiment was conducted to evaluate the effect of different dietary level of cellulose on the biological condition such as protease activity in intestine (APU) and stomach (APL), intestine somatic index (ISI), intestine-body length ratio (PU/PT), the chemical composition of giant gouramy fry stomach-body weigh ratio (BL/BT), and growth rate (DGR), and of giant gouramy fry. Two isonitrogenous (41.942.2% crude protein) and isocaloric (3084.9-3128.9 kcal digestible energy/kg of feed) practical diets contained either 2.6% and 19.3% cellulose/kg of feed respectively, were fed to giant gouramy to giant gouramy fry. Types were fed on the experimental diet at satiation, three times daily for 60 days. Fish fry were placed in each aquarium (60 x 40 x 30 cm in size). The result showed that feed containing 19.3% of cellulose affected in proease activity in intestine (APU) and stomach (APL), intestine somatic index (ISI), intestine-body length ratio (PU/PT), stomach-body weigh ratio (BL/BT) (p<0.05) but it did not affect the specific growth rate (DGR) (p>0.05). AbstrakPercobaan dilakukan untuk mengetahui pengaruh dari pemberian selulosa dalam pakan terhadap kondisi biologis yaitu aktivitas endoenzim (protease) di usus dan lambung (APU dan APL), intestine somatik indek (ISI), hepato somatik indek (HSI), rasio panjang usus/panjang tubuh (PU/PT), rasio berat lambung/berat tubuh (BL/BT), laju pertumbuhan harian (DGR) dan komposisi kimia tubuh benih ikan gurami. Dua macam pakan yang digunakan yaitu yang mengandung protein dan energi yang relatif sama yaitu berturut-turut 41.88-42.25% dan 3084.9-3128.9 kkal/kg pakan, dengan kandungan selulosa yang digunakan dalam pakan masing-masing adalah 2,6 % dan 19,3 %. Ikan di pelihara dalam akuarium dengan menggunakan sistem resirkulasi. Masing-masing akuarium diisi ikan sebanyak 50 ekor dengan bobot awal 0.6-0.8 gram. Selama pemeliharaan ikan diberi pakan sampai kenyang. Ikan diberi pakan tiga kali sehari yaitu pukul 8 pagi, 12 siang dan 4 sore. Setelah 60 hari pemeliharaan (pada akhir percobaan) dilakukan evaluasi pengaruh selulosa terhadap kondisi biologis benih ikan gurami yaitu APU dan APL, ISI, HSI, PU/PT, BL/BT, DGR dan komposisi kimia tubuh. Hasil percobaan menunjukan bahwa penambahan selulosa sebesar 19,3% dalam pakan memberi pengaruh terhadap APU, APL, ISI, HSI, PU/PT, dan BL/BT (P<0.05), namun tidak meningkatkan laju pertumbuhan benih ikan gurami (P>0.05).
