Abstract

Shrimp red cherry shrimp is one of the ornamental potential developed. One of the conservation efforts can be made to increase production by optimizing keragaannya on enlargement phase. This study aims at scaling up the production of red cherry shrimp, especially in the phase of enlargement. Treatment in the form of background color is composed of (A) without colors (control), (B) white, (C) in black, and (D) red. Each treatment was repeated three times with a 45-day long research. Container maintenance in the form of an aquarium measuring 14x14x14 cm3 volume of 1 l and equipped with aeration. The prawns used were 10 fish / aquarium with a weighted average of 0.018 ± 0.21 g and the total length of the average of 0.82 ± 0.21 cm. Feeding in the form of an ad bloodworm satiation and include aquatic plant Hydrilla sp. as a source of additional food and shelter in the form of detritus. The results showed that the weight gain and the highest long background color was achieved by treatment D (red) which is equal to 0.09 ± 0.3 g and 1.62 ± 0.3 cm. Survival at each treatment reached 100%. The water quality of all treatments during the study period remained within normal limits.

Abstract

The study was based on eight specimens from a single population of Palembang pufferfish. We used a comprehensive approach comprise behavioral record, the Random Amplified Polymorphism DNA technique, exteriorly genital observation and the description of morphological coloration distinctive to recognize gender. Annotation from captivity has yielded that two genders in couple were possessed the prominent social respond in shoaling-fidelity. When the gonadal process has been released by maternal part, eggs and offspring were kept by male and there is no tolerable contact of female were given, here the female has become more cannibalism. Male adult has more brown-blackish and occasionally more flukes-dark on the half upper horizontal body it has less towering bulk and only has one genitalial hole. Female furthermore is recognizable with the present hight-bulk and has more yellow overall flukes in coloration and widely bright yellowish-dark from abdomental part to the edge of middle half of the body. Contrary, female has two genitalian holes. RAPD also has confirmed a concordance linkage what we are previously expected. We found an important mutation 176 bp for both gender. Among the scaffold obtained, scaffold 33 is a common scaffold identified within T. palembangensis and Takifugu, it has a sufficient score bit of 36.2 with a length of nucleotide 1,758,880 bp. Moreover, this scaffold is the result from primer OPP-19 in the female of T. palembangensis, we thus can finally distinguish their sex status. The scaffold 33 might relate to the gene SOX. Our attempt may hatch a new horizon for institutional developers, aquarist and conservationist in case of surety for sustainable natural population and to ensure their stock for consumption and trading ornament requirement.

Abstract

The purpose of these observations was to identify the stages of the embryo development of ikan palmas (Polypterus senegalus senegalus) and determine the length of duration of each stage. Broodstocks were cultured in aquaria 6 cm x 72 cm x 50 cm in size. The broodstock were stocked at ratio of 1:1 and fed ad libitum with earthworm, small feed fish (ting sea fish) and golden snail. The Palmas broodstocks here naturally spawned in artificial nests made of split plastic raffia in resembling the aquatic plant found in the natural habitat of ikan palmas. After 21 days of culture period, the broodstock began to lay eggs in gradually for 20 days. The average diameter of the eggs was 25 μm. The embryo developed in 24 hours after fertilization and hatched out three days after the embryo had developed.

Abstract

A case study of tumour in koi carp (Cyprinus carpio) was observed in rearing periode. This tumour occurs solitary, large, pale red, fleshy masses under the lips and dental plates on the outside, and by reason of its size, may prevent closure the mouth. Moreover, this tumour goes through into the inside of the mouth. At necropsy, there were two soft, firm, small mass at inside of the mouth and the bigger mass at outside the mouth. Samples of this tumour were fixed in 10% formalin were used for histology analysis. The clinical course of the tumour is one of relatively slow but progressive growth. The proliferative stage of the neoplastic process is preceded and accompanied by a striking vascular reaction. Intensed hyperemia invariably occurs in that region of the mucosal surface which later becomes the site of neoplastic proliferation. Neoplastic cells lied around lamina propria and submucosal. These cells were joined together to make vacuolization and the other cells become pleiomorphism with hyperchromatic nucleus and N/C ratio cells are 1:1. In some area, there were many empty holes, around the holes there were debris cells, inflammation cells, and erythrocytes.

Abstract

Penelitian bertujuan untuk mengetahui pengaruh substitusi sumber protein tepung ikan dengan tepung maggot telah diteliti terhadap ikan hias balashark. Sebanyak 1.500 ekor benih ikan balashark dengan bobot awal rata-rata 2,26 ± 0,08 g dan panjang 5,18 ± 0,06 cm ditebar dalam 15 unit bak tembok berukuran 1,2 m x 0,7 m x 0,5 m, sistem resirkulasi dan dilengkapi aerasi dengan padat penebaran 100 ekor/bak dan dipelihara selama 60 hari. Pakan buatan dengan perbedaan substitusi maggot terhadap tepung ikan sebagai pengganti protein diberikan sebagai perlakuan yaitu (a) 0%; (b) 10%; (c) 20%; (d) 30%; dan (e) 40% maggot substitusi. Perlakuan substitusi maggot nyata mempengaruhi (P<0,05) pertambahan bobot, panjang total, pertumbuhan spesifik, retensi protein, dan rasio efisiensi protein. Substitusi maggot hingga level 16,47% memberikan respons terbaik terhadap penampilan tumbuh benih ikan balashark.The objective of this research was to study the effect of maggot meal as an alternative protein source to partially substitute fish meal in artificial feed for balashark fry. This research was conducted at the Research Institute for Ornamental Fish in Depok, West Java. Fifteen concrete tanks each of 1.2 m x 0.7 m x 0.5 m, provided with aerated recirculation water system, were used as culture tanks. Balashark fry averaging 2.26±0.08 g in body weight and 5.18±0.06 cm in body length were stocked into the tanks at a density of 100 fries per tank. The dietary treatments tested were five different levels of maggot meal, namely: (a) 0% substitution; (b) 10% substitution; (c) 20% substitution; 30% substitution, and e) 40% substitution. Feeding of the fries lasted for 60 days. Results of the research showed that, based on body weight gain, total body length, specific growth rate, protein retention, protein efficiency ratio, and lipid retention, the effect of maggot meal to substitute for fish meal was significant (P<0.05). The best growth performance of the balashark fries was achieved by the feed containing maggot meal substitution for fish meal of 16.47%.

Abstract

Spesies ikan hias air tawar dari Indonesia yang diekspor oleh para eksportir terutama dari daerah Jabodetabek sangat banyak. Pasar ekspor merupakan pasar terbesar untuk ikan hias Indonesia. Negara tujuan ekspor hampir ke seluruh dunia, mulai dari Eropa, Amerika, Australia, Jepang, Cina, Hongkong, Singapura bahkan Timur Tengah seperti Iran dan Arab Saudi. Nilai ekspor yang tercatat pada tahun 2000 masih sekitar 4 juta dollar namun tahun 2003 sudah mencapai sekitar 15 juta dollar US versi Badan Pengembangan Ekspor Nasional, dan tahun 2006 sudah dicapai 130 juta dollar US. Walaupun demikian menurut versi BPEN pula Indonesia baru mengisi 9% pasar di Eropa dan 6% ke Amerika, sementara Singapura mengisi 25% dan 30%-nya. Ikan ekspor ini terdiri atas spesies-spesies ikan yang berasal dari perairan Indonesia sendiri dan ikan introduksi dari perairan negara lain seperti Amerika Selatan, Afrika, dan AsiaTenggara lainnya. Produk didapatkan dari hasil tangkapan alam maupun dari hasil budidaya. Beberapa merupakan ikan yang di re-ekspor dari negara asal ke negara pengimpor. Data jenis ikan yang telah dibuat dalam bentuk tabulasi didasarkan dari asal ikan didapatkan dari list beberapa eksportir yang berada di daerah Jakarta, Bogor, Bekasi, dan Depok. Dari data tersebut ternyata ikan asli perairan Indonesia masih banyak yang diambil dari alam (tangkapan), dan ikan introduksi yang masuk dan dibudidayakan disini justru lebih banyak.

Abstract

The Research Institute for Freshwater Ornamental Fish Culture has been conducting domestication research since 2004 on adult freshwater puffer fish or buntal broodstock in which the fish were reared in aquaria and fed with small feed fish teri (anchovy) and earthworm (Lumbricus sp.). The domestication of freshwater puffer fish or buntal has resulted in successful environmental adaptation and reproductive ability of the fish and further rearing of its fry. The adaptive ability was indicated by its high survival rate, good growth and development, and the reproductive success in spawning, egg production, hatching as well as growing of the larvae to fry stages. The mature gonad stage of the fish was reached at an average body weight of 150 g with a reproductive period of 5 months. The spawning occurred naturally and the eggs were gradually released at interval periods of 14—18 days with egg production rates of 1,000—1,900 eggs per spawning. The highest egg fertilization rate was 96%, with the highest egg hatching rate of 78.6%. Hatching process took place on the 6th to 13th days after spawning process. The surviving larvae began feeding filtered natural foods Moina sp. on the 3rd day up to the 6th day, whereas unfiltered Moina sp. was given from the 7th to 14th days. The fish were fed the live feed Culex sp. from the 15th to 30th days. In the following period the fish was fed earthworm and small feed fish teri (anchovy).
