Abstract

Fish fi llet as protein based food will susceptible to damage when stored at room temperature without any treatment. The shelf life of fi sh fi llet at room temperature only just 12 hours. The effort that public have been made to extend it in storage and transport is a cooling system. To reduce the dependency on the ice usage is needed a way or method to be applied, namely active packaging. Some publications mention that the active packaging can inhibit microbial growth on the fi sh fi llet. The purpose of this study was to determine the infl uence of edible coatings were incorporated ekstraks rough Ovocleidin 17 (EKO-17) on the quality of fi sh fi llets during storage. This study was conducted using a randomized block design with three replications simple. Factors to be tested is EKO-17 concentration in edible coatings. The parameters observed in this study is total microbial, TVB-N, protein content, and heavy losses. The results showed that the concentration of EKO-17 signifi cantly affect the total microbial, TVB-N and protein content. EKO-17 concentration of 0.9% with room temperature storage for 27 hours gives the best results, the total microbial 7,27 (106 CFU / g), the TVB-N 17.02 mg / 100 g, protein content of 10.75%, severe shrinkage of 0.43%.

Abstract

Study was conducted to find out the effect of tetracycline medication to suspectibility against MAS, growth rate and hatching rate of African catfish (Clarias gariepinus). The result indicated that intraperitoneal injection of tetracycline (50 mg/kg fish) could decrease the growth rate of fish significantly (P<0.05). However, this medication did not have significant effect to suspectibility of fish against A. hydrophila the causative agent of MAS. Intraperitoneal injection of tetracycline (50 mg/kg fish) in african catfish brooders two weeks before spawning also did not effect fertility or hatching rate of eggs.

Abstract

The objective of this experiment was to study the effect of endosulfan on red blood cells of catfish, C. gariepinus. Ten fishes, (2-3 g of body weight), were kept in 30 l fish tank. Fish were exposed to 5 concentrations of endosulfan (1.71 ppb, 3.43 ppb, 5.14 ppb, 6.85 ppb and 8.57 ppb) for 6 weeks. The experiment was done in triplicates. The result showed that endosulfan caused the red blood cells damage by forming cerroids and lipofuscin complex. This impairment was over 90% of total red blood cells when fishes were exposured to endosulfan at 6.85-8.57 ppb.

Abstract

This study aimed to investigate the species and its composition of sea cucumber in the Kapisawar village of Meos Manswar District in Raja Ampat Regency. This research was conducted from March to April 2014. Descriptive method was applied directly through observations by using belt transects that consisted of three stations. Then, identification of species was done through spicula appearance of sea cucumbers. Results showed that from all research stations, 10 species of sea cucumbers were found, and these species derived from 3 families and 4 genera. The species of sea cucumbers are Holothuria scabra, H. leucospilota, H. rigida, H. sucosa, Bohadschia similis, B. marmorata, B. vitiensis, Synapta maculate, Opheodesoma grisea and Stichopus variegatus. The highest number of sea cucumber species was found in the station I which consisted of 9 species from 2 families and 4 genera, followed by station II (2 families and 3 genera), and the lowest at the station III of 3 species (2 families and 2 genera). Some of the sea cucumber found in the research station were economic importance, with the highest composition was at the station I because of its suitable habitat condition and the lowest in station III due to far from the village.

Abstract

The purpose of this research was to study the limnological status of Cilala reservoir, based on physical, chemical, and biological parameters. The observation comprised some morphometric of surface and vertical dimension, water quality measurements, plankton community structure, and primary productivity. Based on some morphometric condition, Cilala reservoir has a high potention of biological productivity, but the area of lake begins narrowing. The physical and chemical characteristic showed that Cilala reservoir was still in good condition. The condition of Total Suspended Solid (TSS) at inlet and the water debit of outlet showed that the waters has a relatively high potention of sedimentation that lead to a shallowing condition. There were found 95 genus of phytoplankton from seven classes (Bacillariophyceae, Chlorophyceae, Cyanophyceae, Chrysophyceae, Euglenophyceae, Pyrrophyceae, and Xanthophyceae). It was also found four major groups of zooplankton, i.e. Rotifera, Copepoda, Cladocera, and Protozoa. Although the primary productivity was relatively low, based on orthophosphate, chlorophyll-a, and Nygaard Index, the water was in mesotrophic-eutrophic status. As a whole, Cilala reservoir was still appropriate for fisheries activities.

Abstract

Udang windu transveksi merupakan udang yang menggunakan teknologi transgenetik dimana suatu teknologi rekayasa gen dengan mengintroduksikan satu atau lebih Deoxyribo Nucleic Acid (DNA) asing ke dalam tubuh udang dengan maksud memanipulasi genotipenya ke arah yang lebih baik dan selanjutnya di transmisikan ke keturunannya. Aplikasi transfeksi pada udang diharapkan dapat memperbaiki karakterkarakter yang berguna bagi akuakultur seperti peningkatan laju pertumbuhan dan daya tahan tubuh udang terhadap penyakit. Namun demikian, domestikasi udang windu transveksi dengan menggunakan pakan komersial selama ini memberikan pertumbuhan udang yang relatif lambat. Pertumbuhan udang yangrelatif lambat diduga salah satu penyebabnya adalah kebutuhan protein dalam pakan yang belum optimal. Penelitian ini bertujuan untuk mendapatkan kadar protein yang baik untuk mendukung pertumbuhan dan sintasan udang windu transveksi. Perlakuan yang diterapkan adalah kadar protein yang berbeda yaitu: 30%, 40%, dan 50% protein dalam pakan. Penelitian didesain dengan menggunakan rancangan acak kelompok yang terdiri dari 3 perlakuan dan 2 ulangan. Hasil penelitian menunjukkan bahwa kadar 40% protein dalam pakan memberikan efi siensi protein tertinggi dan berbeda nyata (P<0,05) dengan kadar 30% protein dalam pakan, namun keduanya tidak berbeda nyata (P>0,05) dengan kadar 50% proteindalam pakan. Pada kadar 30% dan 40% protein dalam pakan menghasilkan sintasan yang tidak berbeda nyata (P>0,05), namun keduanya berbeda nyata (P<0,05) dengan sintasan udang windu yang diberi 50% protein dalam pakan. Laju pertumbuhan spesifi k udang pada ketiga perlakuan tidak menunjukkan perbedaan yang nyata (P>0,05). Hasil penelitian ini mengindikasikan bahwa dengan kadar 40% protein dalam pakan menghasilkan efi siensi protein dan sintasan yang baik pada udang windu transveksi selama 81 hari pemeliharaan dalam bak resirkulasi.Udang windu transveksi merupakan udang yang menggunakan teknologi transgenetik dimana suatuteknologi rekayasa gen dengan mengintroduksikan satu atau lebih Deoxyribo Nucleic Acid (DNA) asing kedalam tubuh udang dengan maksud memanipulasi genotipenya ke arah yang lebih baik dan selanjutnyadi transmisikan ke keturunannya.
