Increasing global population has resulted in increased urbanization of coastal areas across the globe. Such an increase generates many challenges for sustainable food production and food security. The development of aquaculture has proven to be an extremely good option to ensure food security (uninterrupted supply and good quality of food) by many...

Shipping plays a crucial role in supporting global trade, including the transport of products from the aquaculture industry. However, ships may also unintentionally transport invasive species and pathogens in their ballast water which pose biosecurity risks for aquaculture. The Ballast Water Management Convention was developed to manage the biosecu...

Resting strategies of planktonic organisms are important for the ecological processes of coastal waters and their impacts should be taken into consideration in management of water bodies used by multiple industries. We combined different approaches to evaluate the importance of resting stages in Singapore coastal waters. We used molecular approache...

Dry macroalgae flakes are low cost feed alternatives but live phytoplankton, enhanced by probiotics, substantially increased density per biomass

Rivers are known to be major contributors to eutrophication in marine coastal waters, but little is known on the short-term impact of freshwater surges on the structure and functioning of the marine plankton community. The effect of adding river water, reducing the salinity by 15 and 30%, on an autumn plankton community in a Mediterranean coastal l...

We studied the plankton dynamics of two semi-enclosed marine coastal inlets of the north of Jurong Island separated by a causeway (SW Singapore; May 2012–April 2013). The west side of the causeway (west station) has residence times of ca. one year and is markedly eutrophic. The east side (east station) has residence times of one month and presents...

We analyzed the concentrations of trace metals/metalloids (TMs) in the water, sediment and plankton of two semi-enclosed marine coastal inlets located north of Jurong Island and separated by a causeway (SW Singapore; May 2012-April 2013). The west side of the causeway (west station) has residence times of approximately one year, and the east side o...

The importance of heterotrophic bacteria relative to phytoplankton in the uptake of ammonium and nitrate was studied in Mediterranean coastal waters (Thau Lagoon) during autumn, when the Mediterranean Sea received the greatest allochthonous nutrient loads. Specific inhibitors and sizefractionation methods were used in combination with isotopic 15N...

Singapore lies in a biodiversity hotspot and is considered very rich in species due to its geographic position and climate. To understand Singapore’s aquatic ecosystems, it is essential to first determine the composition of planktonic assemblages and assess their functional diversity. Phytoplankton organisms are at the base of the aquatic food web...

Introduction of the use of flow cytometry in Ballast water

The island of Singapore is located between 1°09'N–1°29'N and 103°38'E–104°06'E at the confluence of the Malacca Straits and the South China Sea. To date, both the marine and freshwater zooplanktons of this area are poorly studied, and availability of taxonomic identification is scarce. Moreover, most of the studies were published between the 1950s...

In order to limit the risk associated with invasion of habitats by exogenous species, the International Convention for the Control and Management of the Ships' Ballast Water and Sediments was adopted in February 2004 and may soon enter into force. The International Maritime Organization (IMO) has produced guidelines to assess the efficacy and relia...

Over half of the total nitrogen, phosphorus, silicate and dissolved organic carbon (DOC) loading was discharged from the Vène River into the Thau Lagoon waters within the first five days of what was considered to be the autumn flash flood period. Such loads represented about 8% and 3% of the yearly averaged total nitrogen and phosphorus load in Tha...

Black Carbon (BC) is a form of aerosol emitted as soot during biomass burning or coal and diesel combustion. BC is associated with other aerosols (sulfates, nitrates, organic acids…) and contributes to global warming and climate change. Studies have also shown that BC could alter sedimentation and microbial processes in the water column. The aim of...

For several decades, prokaryotic and eukaryotic inhibitors have been used to exclude bacteria from microalgal cultures and for investigating prey-predator relationships. Recently there has been considerable interest in using specific inhibitors for studying the interactions between bacteria and phytoplankton, by selective repression of either organ...

The Grande-Entrée Lagoon (Magdalen Islands, Canada) has supported mussel (Mytilus edulis) cultivation for the last 25 years. Algal biomass in this lagoon is relatively low while heterotrophic plankton biomass is high. Although often considered herbivorous, it is known that filter-feeding bivalves can consume various types of food, from bacteria to...

Mussel culture has been on-going since 1984 in Grande-Entrée lagoon (Magdalen Islands, Gulf of St. Lawrence, Canada). This industry has grown approximately 10-times, to about 180 tons y−1 in 2006. The goal of this study was to examine the influence of mussel farming in this lagoon, focusing on the planktonic communities. The influence of the suspen...

Mussel culture in coastal environments relies on the availability of food of sufficient quality and quantity. Both to determine this availability and to examine impacts that this aquaculture practice may have on the environment, it is important to have good knowledge of the type of plankton communities present in aquaculture sites. It is usually th...
