ABSTRACT

Digestibility of carbohydrates in fish is relatively low because of the availability andactivity of the amylase enzyme  in the digestive tract of fish is quite small. This study aimed at evaluating the role of probiotics in the addition of a high carbohydrate-based feed to improve growthperformance of tilapia(Oreochromisniloticus).This study consisted of 4 treatmentswith 3 replicates,namely controls, 0.5% ; 1%  and 1.5%probiotics.  The results  showed that the greatest specific growth rate was found in the probiotic treatment of 1%, followed by that of 1.5%, 0.5% and the control, respectively. Similar results were also found in the feed efficiency, feed consumption, the population of bacteriain the digestive tract and the retention of feed, where the largest value contained in the probiotic treatment 1%,then followed by the probiotic treatment of 1.5%, 0.5% andcontrol treatment. Therefore, the addition  of 1% probiotic in the highly carbohydrate-based feed can improve the growth performance of tilapia.

ABSTRACT

The shrimp pasteproductsis one ofthe traditionallyprocessed productsby fermentation. Shrimp paste productsare familiarin everylayer ofsocietyinIndonesia, which is commonlyusedas a flavoringdishes. A study to identify the diversity of shrimp pasteproducts have been carried to know the home industry diversity ofshrimp pasteproducts,in Banten province  as well asits  physicalquality. The shrimp paste products diversity was observed in the market directly and also by interview with the producerin Banten Province.The identification of shrimp paste product was conducted withphysical  test of filth, that was theforeign materials that mixed-up with  rawshrimp pasteproducts.The results showed that there were different raw materials used as well as the product forms, processing, physical quality of the product, pricing and marketing distribution of the shrimp paste products. Almost-uniform product of shrimp paste were found between Pandeglang (TP) and Serang (TS) shrimp paste product, while that of Domas (TD) and Binuangeun (TB) were relatively same in its diversity.  Domas (TD) and Binuangeun (TB) shrimp paste product were of good quality, made of terasi shrimp, without  dyes additive, and fillers. While that of Pandeglang (TP) and  Serang (TS) were of low quality due to the  use of waste of salted fish, dyes, and  filler material.

ABSTRACT

The highly demand of coral reefs trading in various countries, have endangered to the coral reef condition in Indonesia. Many people exploited the coral reef bed to yield part of their needs of incomes. Therefore,  serious conservation efforts are urgently  needed. In this relation a study have been  carried  out to observe the survival and growth rate of transplanted coral reefs in Pramuka resort of Seribu Islands.  In this study four species of coral reefs were used as the experimental objects which were transplanted into cemented substrates. They were, namely Acropora formosa, Hydronopora rigida, Pocilopora eydousi, and  Seriatopora hystrix. The fragment of these coral were measured every month  for their length and survival. The results showed that survival rate were ranged from 89.06 to 100% and the length gained were varied after 5 month transplantation from 6.4 cm for Acropora formosa  (highest) and 0.74 cm for  Hydronopora rigida. (lowest)

ABSTRAK

               Kakap Putih (Lates calcarifer Bloch) adalah salah satu ikan ekonomis penting yang benihnya dapat diproduksi Thailand. Data genetik merupakan salah satu aspek penting dalam mengatur pemijahan induk untuk pemuliaan, namun hingga saat ini informasi terkait keragaman genetiknya masih minim. Penelitian ini bertujuan mengkaji keragaman dan perbedaan genetik kakap putih pada tiga populasi hatchery dan dua populasi alam  di Thailand dengan menggunakan metode gabungan antara Restriction Fragment Length Polymorphisms dan Polymerase Chain Reaction (PCR-RFLP) pada D-loop control region di DNA mitokondria. Ditemukan tujuh potongan endonuklease dari 268 sampel yang diamati. Populasi alami Chantaburi (CH) memiliki keragaman haplotipe dan nukleotida tertinggi (h = 0.6626, π = 0.0554) dibandingkan populasi lainnya: tiga populasi hatcheri yaitu Rayong (RA), Chonburi (CB) dan Nakhon Si Thammarat (NK) ) (h berkisar antara 0.2709 – 0.3227; πberkisar antara 0.0195 – 0.386) danpopulasi alam Nakhon Si Thammarat (PN) (h = 0.172, π = 0.0091).Mismatch distribution analysis mengungkap kejadian bottleneck pada beberapa generasi sebelumnya di populasi alam PN danseluruh populasi hatcheri. Analysis of Molecular Variance (AMOVA) menunjukkan 88.95% keragamandisebabkanperbedaan dalam populasidan 11.05 % disebabkan perbedaan antar populasi. Perbedaan genetikyang signifikan terdapat pada perbedaan antar populasi alam (Φ_ST = 0.239, P<0.001), namun perbedaan antar populasi hatchery tidak signifikan, menunjukkan terjadi pencampuran genetik sekerabat antar satu dengan hatcheri lainnya. Hal ini karena minimnya masukkan indukan baru dari alam. Kedua hal tersebut dapat menurunkan keragaman dan perbedaan genetik pada setiap populasi hatchery dan antar populasi hatchery. Data awal penelitian ini dapat digunakan untuk pengelolaan induk, upaya pemuliaan dan monitoring genetiknya di Thailand.

ABSTRAK

Nostoc merupakan jenis blue green alga yang bisa dijadikan sumber protein potensial bagi manusia. Penelitian ini bertujuan untuk mengevaluasi kandungan protein dan klorofil a dari Nostoc yang dikultur di dua media, Modifikasi Bristol dan BG 11 media, dengan perbedaan konsentrasi MgSO₄.7H₂O. Di antara kedua media kultur, Nostoc yang dikultur pada modifikasi Bristol media memiliki protein dan klorofil a lebih tinggi dari Nostoc yang dikultur dengan BG 11 media. Berat kering Nostoc dengan Bristol (0.02 - 0.34 gram) lebih tinggi dari BG 11 (0.02 – 0.14 gram). Kandungan protein Nostoc pada Modifikasi Bristol media lebih tinggi (283.58 – 79149.77 µg/gram berat kering) sedangkan yang dikultur dengan BG 11 media (19.31 – 2536.95 µg/gram berat kering). Untuk kandungan klorofil a BG 11 media broth (0.003 – 1.67 mg/gram berat kering) lebih tinggi dari pada Modifikasi Bristol media (0.04 – 1.05 mg/gram berat kering). Perbedaan konsentrasi MgSO₄.7H₂O.  pada kedua media kultur berpengaruh pada kandungan protein dan berat kering dari Nostoc, akan tetapi tidak berpengaruh pada kandungan klorofil a. Penambahan 0,075 gram/liter konsentrasi MgSO₄.7H₂O selama tiga minggu kultur merupakan kondisi optimal untuk mendapatkan kadar protein dan klorofil a yang optimal untuk modifikasi Bristol media sedangkan pada BG 11 media kandungan protein dan klorofil a yang dihasilkan optimal pada 0,000 gram/liter MgSO₄.7H₂O. selama satu minggu kultur.

ABSTRACT

Pathogenic bacterial namely Streptococcus sp has widely spreads in Seabass culture, particularly in fingerlings. It might caused decreasing production quality and quantity. To improve this problem, a study have been done to feed the seabass by using the combination of immunostimulan and antibiotics. The parameter observed were the  survival rate and growth rate. Juveniles of 2 cm in size with Streptococcus symptoms were reared in 6 units of 2 m³ tanks with stocking density  of 5,000 fishes per tank. They were fed with artificial feeds mixed by immune stimulant and antibiotics (5gr/kg and 2gr/kg, respectively). The experiment was done with 3 replicates and one control for 20 days. The results showed that the survival rates were significantly different between A and B (control) with 20.2% (3,030 ind) and 12.5% (1,875 ind), respectively. There were no significant different in the growth rates between A and B with body length  5.90 cm and 5.80 cm, respectively.

ABSTRACT

VNN or Viral Nervous Necrosis is one of dangerous pathogen which might could infects some marine fishes.This virus has  various type of resistance level to different  marine fish. An attempt to test the fishes which have highest level of resistance for VNN virus have been conducted. About 0.1 ml of VNN virus extract were injected to seven economic fish species.    Prior the treatment, all fishes were tested using the PCR technique. The data were analysed by variance of randomized block design consisted  of  treatments and control. The results showed that the VNN virus injection to the fish group have significant impact at 1%  level. Results of challenge test showed that Silver Pompanos have the strongest resistance against VNN virus compared to the other species with 90% of survival rate , while the PCR test  showed no esophageal VNN. While the Humpback groupers have the weakest resistance with 20% of survival rate with PCR test showed that VNN infection have severe stages.

ABSTRACT

The potential fisheries in Indonesia has been used by the community in various ways and scale. Most of the existing fishing effort is a small-scale business with a variety of problems faced including the increase in cost, aquatic environment degradation, decline in the catch as well as problems related to non-targeted fishes. In order to overcome these problems required an Appropriate Technology so that  the small-scale fishing enterprises can continue to evolve. Types of appropriate technology or so called TTG, which can be adopted to improve the efficiency of small-scale fishing enterprises, namely: attractor squid, deep-sea traps,  and fish meat bone separator "Suritech ™". The presence of TTG is expected to provide added value both in economic, ecological and sustainability of fishery resources so that sustainable fisheries can be realized and felt by all walks of life.
