Episodic acidification (pH <5) of estuarine tributaries caused by the oxidation sulfidic floodplain sediments is widespread in eastern Australia. Drainage and flood mitigation works promote export sulfuric acid dissolved aluminium iron into streams. This paper examines a tidal reach on Richmond River, New South Wales. Acid discharge controlled water balance, drainage shallow groundwater, floodgate operation. Floodgates store waters for more than six months. discharges ranged from short...
The state of global freshwater ecosystems is increasingly parlous with water resource development degrading high-conservation wetlands. Rehabilitation challenging because necessary increases in environmental flows have concomitant social impacts, complicated many rivers flow between jurisdictions or countries. Australia’s Murray–Darling Basin a large river basin such problems encapsulated the crisis its Ramsar-listed terminal wetland, Coorong, Lower Lakes and Murray Mouth. Prolonged drought...
Acid sulphate soils form when iron pyrite oxidises to sulphuric acid on atmospheric exposure, lowering soil pH below 4. In the Richmond River estuary, northern New South Wales, flood mitigation, drainage works and floodplain excavations have augmented formation by increasing availability for oxidation. These engineering facilitated transport of acidified water impeded recovery from tributary acidification. The increased frequency duration acidification are associated with elevated...
Nile tilapia, Oreochromis niloticus is the third most commonly farmed finfish species in world, accounting for nearly 5% of global aquaculture production. In past few decades much success this has been attributed to development and distribution Genetically Improved Farmed Tilapia (GIFT). Despite increasing availability GIFT, productivity small-scale farming remains highly variable, particularly developing nations. Commercial fish-feed pellets can increase fish farm productivity; however,...
Estuarine acidification caused by outflows from acid sulfate soils (ASS), impacts many estuaries in eastern Australia. Affected waters are characterized low pH and elevated concentrations of metals, particularly iron, aluminum, manganese. The effects associated with ASS-affected water, on adult Sydney rock oysters Saccostrea glomerata have not been previously studied detail. Most production occurs along the Australian east coast has significantly decreased over last 30 y. To investigate poor...
Abstract The widespread degradation of mangroves has been attributed to their conversion into other land uses and purposes, most notably destruction construct extensive brackishwater aquaculture ponds. This study investigated the relationship between environmental factors management alternatives for an integrated mangrove-aquaculture system in Derawan Island District, Berau Regency, East Kalimantan Province, Indonesia. collected a total 56 soil water samples from around 50 ha assess limiting...
Nile tilapia (Oreochromis niloticus) is currently one of the most farmed freshwater fish and contributes significantly to total global aquaculture production. The genetically improved strain O. niloticus (GIFT) was introduced Papua New Guinea (PNG) in 1999 improve food income security. high cost low availability commercial feed hinder growth GIFT farming PNG. Stable carbon nitrogen isotopes were used determine role supplementary natural sources diet pond-based aquaculture. Two treatments...
Seafood elemental profiling (SEP) is the quantification of a range elements in seafood products and may serve addressing questions provenance quality. Traditional methods for analyzing soft tissue present several limitations industry-level use SEP. Portable handheld X-ray fluorescence (pXRF) analysis promising alternative to conventional methods; however, its application biological has not been fully established. Intact giant tiger prawn (Penaeus monodon) abdomens were analyzed with Vanta M...
Estuarine acidification, caused by disturbance of acid sulfate soils (ASS) is a problem that affects many estuaries in eastern Australia. ASS outflows have low pH and elevated concentrations metals, principally iron aluminum. Most production Sydney rock oysters Saccostrea glomerata occurs along the Australian east coast estuarine acidification has been implicated localized declines oyster production. areas recurrently impacted higher levels mortality reduced growth compared with sites are...
<p>Acid sulfate soils (ASS) contain sufficient pyrite which, when oxidised following excavation for brackishwater aquaculture ponds, will generate acid and mobilise toxic metals. Production in affected ponds can be low due to poor growth of shrimp fish, mass mortalities stock plankton blooms. The resultant soil pH also cause klekap production the retention phosphorus associated with elevated concentrations Fe Al pond soils. A series experiments was conducted determine effects different...
The Mekong Delta is the most important rice- and shrimp-producing region for food economic security in Vietnam. Rice-shrimp farming practised where salinity fluctuates substantially between wet dry seasons. Research points to several potential risk factors rotational systems, but how these link directly both rice shrimp production remains poorly quantified systems that stock harvest animals year-round. We examined water soil quality of 18 rice-shrimp-crab ponds, which crab are grown seasons,...
