Dissimilatory nitrate reduction processes in surface sediments of shrimp ponds during the culture period

open access: yesFrontiers in Marine Science, 2022
Intensive aquaculture in estuaries and coasts has resulted in several ecological and environmental problems. Among various nitrogen transformation pathway, dissimilatory nitrate (NO3-) reduction is considered to be highly important in regulating reactive

Methane dynamics of aquaculture shrimp ponds in two subtropical estuaries, Southeast China: dissolved concentration, net sediment release, and water oxidation [PDF]

open access: yes, 2019
Aquaculture ponds are potentially large sources of atmospheric methane (CH4) that can exacerbate climate change. A thorough understanding of various CH4 biogeochemical processes occurring in the ponds is essential for the prediction and management of CH4

Comparison of Quality Changes in Eurasian Perch (Perca fluviatilis L.) Fillets Originated from Two Different Rearing Systems during Frozen and Refrigerated Storage

open access: yesFoods, 2021
The current knowledge on how different Eurasian perch rearing systems impact the final fillet quality is scant. Therefore, two domestic storage conditions were investigated—10 months frozen (−20 °C) and 12 days refrigerated (+4 °C) storage conditions—in ...

Medium-term performance and maintenance of SUDS:a case-study of Hopwood Park Motorway Service Area, UK [PDF]

open access: yes, 2008
One of the main barriers to implementing SUDS is concern about performance and maintenance costs since there are few well-documented case-studies. This paper summarizes studies conducted between 2000 and 2008 of the performance and maintenance of four ...

IMPERVIOUS DEVICES OF OXIDATION POND IN A BASIN

open access: yesBulletin of the Korkyt Ata Kyzylorda University, 2021
The need to use anti-filtration devices in the biopond bowl usually arises when the levels of waste liquid in them exceed the surface water table in the banks of the gully and, therefore, it is possible for this liquid to spread out of the biopond.
