Abstract

The cultivation of giant gourami is constrained by its high mortality due to low resistance to diseases. Resistance is an inherited character from the parental to their seeds. High resistance seeds can be selected using molecular marker, such as Major Histocompatibility complex (MHC) gene. Resistance character is assumed to be different among individual from different broodstocks and is suggested related to their genetic constituent.  This research aims to analyze the resistance of sowang gouramy seeds from different broodstocks and describe genetic character of seeds from different broodstocks. An explorative survey was perfomed. One hundred individuals were taken purposively from Balai Benih Ikan Sikamaju Ciamis West Java and hundred individuals were bought from fish farmer in Ciamis West Java. Sampling was performed in 2015 for the first seed group and in 2016 for the second seed group. Samples were subjected to Aeromonas hydrophila and Pseudomonas aeruginosa infection. The fragments of MHC gene were amplified using PCR technique from eight individual of first group and six individuals of second group. The resistance characteristic was analyzed using simple mathematics based on the number of living seeds compared total infected seeds and molecular characteristics was analyzed descriptively based on DNA band pattern. Different resistance to A. hydrophila was observed between seed groups from different broodstocks. The seeds group from the first broodstocks showed lower resistance level with the value of 29% than that from the second broodstocks with the resistance value reached of 100%. Both seed groups also showed resistance differences to P.aeruginosa, although  not as high as A.hydrophila infection. The differencies were also reflected in their MHC gene between seed groups from two different broodstocks. The amplication of MHC gene of the seeds from the first broodstacks resulted of 585 bp and 400 bp length fragments, while from those second broodstocks was only resulted of 400 bp frament. The differences on DNA band pattern between seed groups indicate a different molecular characteristics among seeds from different broodstocks.Usaha budidaya ikan gurami terhambat oleh tingginya mortalitas benih karena rendahnya resistensi terhadap penyakit. Resistensi merupakan sifat yang diwariskan dari tetua ke anakan. Benih yang resisten dapat diseleksimenggunakan marka molekuler seperti gen Major Histocompatibility complex (MHC). Sifat resisten diduga berbeda diantara benih yang beraasal dari induk berbeda dan diduga terkait dengan kompenen genetik yang dimiliki. Tujuan penelitian ini adalah untuk mengetahui sifat reisten dan karakter molekuler benih gurami sowang asal induk berbeda. Fragmen gen MHC diamplifikasimenggunakan teknik PCR. Sifat resistensi dianalisis menggunakan perhitungan matematika sederhana berdasarkan jumlah benih hidup dibagi jumlah total benih yang diinfeksi, sedangkan karakter molekuler dianalisis secara deskritif berdasakan pola pita yang dihasilkan. Kedua kelompok benih memiliki sifat resistensi berbeda terhadap Aeromonas hydrophila. Benih dari induk pertama memiliki sifat resistensi lebih rendah dengan nilai kelangsungan hidup sebesar 29% daripada kelompok benih dari induk kedua yang memiliki kelangsungan hidup mencapai 100%. Kedua kelompok benih juga memperlihatkan perbedaan sifat resisten terhadap P. aeruginosa, meskipun perbedaannya tidak sebesar terhadap A.hydrophila. Perbedaan tersebut juga tercermin pada gen MHC kedua kelompok benih. Pada kelompok benih pertama dihasilkan dua fragmen gen MHC dengan ukuran 585 pb dan 400 pb, sedangkan dari kelompok benih kedua hanya dihasilkan fragmen berukeuran 400 pb. Perbedaan pola pita diantara kedua kelompok benih tersebut merupakan idikasi adanya perbedaan karakter molekuler pada benih yang berasal dari dua induk berbeda

Abstract

Abstract. The objective of the present study was to collect information of fishermen perceptions  in Aceh Besar district. The study was conducted from June to August 2012, while the field survey conducted on 21 to 28 June 2012 at some fishing villages in Aceh Besar district namely: (a) Baitussalam and Mesjid, (b) Peukan Bada, (c) Leupung, Lhoknga and Lhoong, (d) Pulo Aceh, (e) Seulimum. The Results showed that most of  respondents were  in the productive age (31-45 years).  The majority of the respondents have recieved subsidies from a variety of sources both government and non-governmental organizations. The common type of subsidy were in the form of goods (in kinds) namely: boats, fishing gear and boat engines, and small portion in cash. In addition, the majority of fishermen stated that the type of assistance provided was in accordance with their needs as fishermen and most fishermen are still expected that fisheries subsidies should be continued. In regard to environmental  and conservation issues that  most fishermen agreed with the conservation area in the district of Aceh Besar. However, most of the respondents stated that they have not been involved in conservation activities. The fishermen need training in fishing technology, post harvest and conservation.Keywords: Habitat degradation, fish, skills and capital

Abstract

This study aimed to investigate the efficiency of fish silage mixed in compounded diets on growth and survival rate of grouper (Epinephelus coioides). Grouper (2,34±0,24 cm, and 4,17±1,82 g) were divided into four groups and cultivated in 1x1x1,5 m floating net cages. Each group fed with compounded diets containing 0, 1, 3 and 5 g/kg fish silage diet twice daily. Fish were sampled for growth performances and feed efficiency at 14 days interval for 10 weeks. Results indicated that compounded diets at 1 and 3 g/kg silage affected the growth rate. Total length, specific growth rate and weight gain significantly increased in fish received 1 and 3 g/kg silage diets. The feed intake seen to be highest in groups administered 3 g/kg silage, whereas the best feed conversion ratio was found in fish fed 1 g/kg silage. Thus, this study indicated that using fish silage in compounded diets may affect feed efficiency and growth performances of grouper juveniles.Keywords:Artificial dietFeedingFish silageGrouperNet cages

Abstract

Green mussel (Perna viridis) has filter-feeding habits and a sessile way of life, with the main food components of plankton and organic matter in the waters. These food components can contaminate green mussels when it accumulates heavy metals. Therefore, this study aims to evaluate heavy metals content and the bioconcentration of lead (Pb), mercury (Hg), and cadmium (Cd) in green mussels based on different sizes and ages. The study was conducted on Pasaran Island, Lampung, Indonesia, and used green mussels aged 3, 5, 7 to 9 months as samples, with 2 replications. The AAS (Atomic Absorption Spectrophotometry) method was used in the analysis of Pb, Hg, and Cd, sampling technique used purposive sampling. The result showed that green mussels at different ages and sizes has impact on Pb content, while an increase of one unit of age and size of green mussels has no effect on the metal content of Hg and Cd. Furthermore, the highest bioconcentration of Pb and Hg was obtained at 9 months, while Cd was observed at 3 months. Based on the results of this study it can be concluded that the simple linear regression appropriate a functional relationship between Pb and the different ages and sizes green mussels cultivated on Pasaran Island , while heavy metals Hg and Cd appropriate with a polynomial quadratic approach and almost do not exist in the form of a functional relationship between Hg and Cd with the different ages and sizes green mussels. Even though it contains heavy metals in below the maximum limit, but care needs to be taken in addressing this phenomenon due to its nature heavy metals that can accumulate in living tissue, thus consuming green mussels containing heavy metals even in relatively small amounts is not recommended.Keywords:Filter feederSessileAccumulateOrganic matterContaminate
