Pendugaan Fungsi Keuntungan Dan Skala Usaha Budidaya Pembesaran Ikan Bandeng Di Kecamatan Palang Kabupaten Tuban Jawa Timur

The Chanos chanos Forsk fish culture, at the present time has been growing and made important role in economic. This paper purposed to examine factors affected on the profit rate earned form Chanos chanos Forsk fish cultured, achievements of the short run profit maximization, and conducted resulted from the culture\u27s return to scale. The research was conducted in Palang Sub District Tuban District, South Java during July to September 2003. The area sample was selected by purposively and the respondent of fish farmer was selected by stratified random sampling. The result of study show that simultaneously the fish seed, feed seed, human labor, culture area wide and investment capitals were affected the profit earned for fish farmers with highly significant levels. Result was also indicate that the farms in location research were hardly provide the maximum profit and the return to scale was calculated to be increased. Considered with the phenomena\u27s, the development of Chanos chanos Forsk fish culture in Palang Sub District Tuban District, Shout Java suggested to be done by culture intensive method

Histological analysis of Milkfish (Chanos chanos, Forskal) which was stunting

Ikan bandeng ( Chanos chanos ) merupakan ikan penting yang bernilai ekonomi. Ikan bandeng banyak dikonsumsi karena memiliki nilai gizi yang tinggi. Ikan bandeng juga digunakan sebagai umpan hidup untuk memancing. Dalam sistem budidaya ikan bandeng peningkatan produksi merupakan faktor yang sangat penting. Salah satu upaya untuk meningkatkan produksi dalam sistem budidaya ikan adalah dengan menerapkan padat tebar yang tinggi. Kendala penerapan padat tebar yang tinggi menyebabkan pertumbuhan bandeng tidak merata, bahkan ada yang kerdil, yaitu kondisi ikan mengalami pertumbuhan yang lambat. Penelitian bertujuan untuk mengamati kondisi jaringan bandeng dengan ikan tidak kerdil dan kerdil. Ikan bandeng ( Chanos chanos) yang digunakan adalah ikan yang sudah dipelihara selama 6 bulan. Organ ikan yang menjadi sampel observasi adalah ikan stunting dan non stunting. Organ yang diamati adalah insang, otot, dan usus. Hasil penelitian menunjukkan bahwa bandeng ( Chanos chanos ) yang mengalami stunting mempengaruhi kondisi insang, otot dan jaringan usus. Insang mengalami edema dan nekrosis. Otot mengamati edema, merosot serat otot, dan nekrosis. Usus mengalami nekrosis atau kematian sel

Temperature and Salinity Effects on Bioaccumulation, Gill Structure, and Radiation Dose Estimation in the Milkfish Chanos chanos Exposed to 137Cs

The present trend of global warming has led to an increase in seawater temperature and salinity. The effects of increasing salinity and temperature on the accumulation of 137Cs by milkfish Chanos chanos was studied under laboratory conditions to obtain information on Chanos chanos adaptability under environmental changes. The uptake of radioactive cesium by Chanos chanos increased with temperature of seawater. The concentration factors (CF) of 137Cs for temperatures of 25°C, 27°C, 29°C, and 31°C at steady state period were 5.25, 5.91, 6.78, and 9.98 mL g-1 for the whole-body of Chanos chanos. The concentration factors at steady state (CFss) of 137Cs for salinities of 26‰, 29‰, 32‰, and 35‰ were 6.23, 9.93, 9.24, and 6.86 mL g-1, respectively. After temperature exposure to 31°C, the fish gills showed hyperplasia of epithelial cells in branchial secondary lamellae, congestion of blood vessels, and hypertrophy of pillar cells. The fish from the treatment group exhibited hemorrhage between the branchial secondary lamellae and an abundance of mucous substance in comparison with control group. This study links radionuclide bioaccumulation data and monitoring data obtained in the field and laboratory experiment with radiation dose determined by ERICA Tools, an approach that will enable better linkages to be made between exposure and dose in Chanos chanos and its marine food web.Received: 2 November 2015; Revised: 1 July 2016; Accepted: 17 July 201

Histological Observation Of Milkfish Organs With Stunting Phenomenon

Milkfish (Chanos chanos) is an important economic fish. Milkfish is widely consumed because it has high nutritional value. Milkfish is also used as live bait for fishing. In the milkfish cultivation system, increasing production is a very important factor. One of the efforts to increase production in fish farming systems is the application of high stocking density. Constraints to the application of the high stocking density cause the growth of milkfish to be non-uniform, some of them even experience stunting, which is a condition in which the fish experience slow growth. This study aims to observe the condition of the milkfish tissue with normal growth and stunted fish. Milkfish (Chanos chanos) used are fish that have been reared for 6 months. Fish organs that were sampled for observation were stunted and normal (non-stunting) fish. The organs observed were the gills, muscles, and intestines. The results showed that stunted milkfish (Chanos chanos) affected the condition of the gill tissue, muscles, and intestines. The gills are edema and necrosis. Muscles undergo edema, degeneration of muscle fibers, and necrosis. The intestine experiences necrosis or cell death.Keywords: Milkfish; Stunting; Histology.AbstrakIkan Bandeng (Chanos chanos) merupakan ikan bernilai ekonomis penting.
