BACKGROUND The microsporidian Enterocytozoon hepatopenaei was first described from Thailand in 2009 in farmed, indigenous giant tiger shrimp Penaeus (Penaeus) monodon. The natural reservoir for the parasite is still unknown. More recently, a microsporidian closely resembling it in morphology and tissue preference was found in Thai-farmed, exotic, whiteleg shrimp Penaeus (Litopenaeus) vannamei e...
The survival rate of Penaeus monodon was monitored for a decade (2010-2019) in two shrimp culture ponds at Chemaguri located Sagar Island the Indian Sundarbans delta complex. exhibited significant variations terms cultured species, which is attributed to nitrate, phosphate, and dissolved oxygen. root cause such difference related variation stocking density species (10 PL20/m2 pond 1 25 2) resul...
Climate change greatly influenced aquaculture in the Philippines and deteriorating water quality; effect, fish production reduced drastically. Thus, farmers researchers have been searching for innovative technologies to address these issues. One technology is biofloc systems. This uses a zero-water exchange accumulates microorganisms that serves as food source. In biofloc, quality management hi...
Shrimp farming and exporting is the main income source for southern coastal districts of Mekong Delta. Monitoring these shrimp ponds helpful in identifying losses incurred due to natural calamities like floods, sources water pollution by chemicals used farming, changes area cultivation with an increase demand production. Satellite imagery, which consistent good spatial resolution providing freq...
Molecular characterization of bacteria and archaea in a bioaugmented zero-water exchange shrimp pond
Abstract In the zero-water exchange shrimp culture pond maintained with application of indigenous bioaugmentor, low levels total ammonia–nitrogen were reported, indicating relevance microbial communities. Sediments (0–5 cm layer) sampled from (85th day) and bacterial archaeal communities; specifically, ammonia oxidizers (ammonia-oxidizing bacteria, ammonia-oxidizing archaea, anaerobic bacteria)...
Padang Pariaman Regency is one of the coastal regencies in West Sumatra which brackish aquaculture have been developed recently, especially shrimp pond aquaculture. This study was conducted to convey pond's general condition, including current status and problems development. The method used a desk through description problems. Based on study, development ponds increased quickly (63.77 ha) unti...
The rapid development of shrimp aquaculture has resulted in numerous ecological problems, thereby necessitating the assessment its sustainable development. This study employed footprint method to conduct a quantitative analysis environmental ramifications two culture modes (pond and factory) Penaeus vannamei. includes horizontal comparison between different vertical among links same mode, with ...
In entering the era of industry 4.0. where internet world has main role as a link to every device collect and analyze data. Internet Of Things (IOT) technology can optimize previous technologies. fishing industry, Indonesia potential for fishery land in 2020 1,201,275 ha. The large area water aquaculture such vannamei shrimp. Water quality pH, turbidity level shrimp feeding schedule ponds are c...
Midterm congressional elections provide an interesting testing ground for theories of voting and elections in America. Free from the contamination of national personalities and stylized issues that epitomize presidential campaigns, midterm elections provide a cleaner issue environment for investigating the effects of systematic short-term forces on congressional elections. The seemingly inevita...
Worldwide, an estimated 35 % of mangrove forests have been lost between 1980 and 2005-among other reasons due to expansion of aquaculture production systems. In Vietnam, where the total mangrove area decreased from 269,150 ha in 1980 to 157,500 ha in 2000, regulation of such systems in the form of 'mangrove-to-water surface ratio' has had limited success to halt these losses. In this study, a s...
