Chaetoceros is probably the largest genus of marine planktonic diatoms with approximately 400 species described, although many of these descriptions are no longer (when?) valid. It is often very difficult to distinguish between different Chaetoceros species. Several attempts have been made to restructure this large genus into subgenera and this work is still (when?) in progress.

The nutritive value of Isochrysis galbana (Tahitian), Chaetoceros calcitrans, Chaetoceros muel-leri. and their bi- and trialgal combinations for Pacific scallop Argopecten ventricosus spat culture.
Helga E. Guderley, Isabelle Tremblay, in Developments in Aquaculture and Fisheries Science, 2016. Sensitivity of Performance to Diet. To assess the impact of diet upon escape response capacity, adult Argopecten purpuratus were fed either Chaetoceros calcitrans or Isochrysis galbani (T. iso).Escape response behaviours were measured before and after feeding these diets for 6 weeks.

The diatom Chaetoceros calcitrans forma pumilum is an important dietary component for cultured GreenshellTM mussel larvae, Perna canaliculus. However concerns surrounding potentially deleterious side effects have motivated a series of experimental trials to optimise the safe usage of this alga. Bioassays involved raising veliger larvae in the purpose-built Cawthron Ultra-Density Larval rearing.
The Pacific oyster, Japanese oyster, or Miyagi oyster (Magallana gigas), previously and currently also known as Crassostrea gigas, considered by part of the scientific community to be the proper denomination as an accepted alternative in WoRMS, is an oyster native to the Pacific coast of Asia.It has become an introduced species in North America, Australia, Europe, and New Zealand.

Stable carbon and nitrogen isotope analyses were used to evaluate the influence of microalgal diet on growth and survival of hatchery-reared Pacific oysterCrassostrea gigas larvae.D-veliger larvae were fedmonospecific diets of Pavlova lutheri (P), Tahitian Isochrysis aff.galbana (T), and Chaetoceros calcitrans (C), and a standard hatchery trispecific diet of 25P:25T:50C (PTC).
During the summer of 2001, a mass mortality of early juvenile Pacific oysters, Crassostrea gigas Gmelin, was observed at a farm site in Jervis Inlet, British Columbia. During this episode, several toxin producing and potentially harmful algae were detected within the phytoplankton community, with a bloom of Protoceratium reticulatum (Claparede et Lachmann) Buetschli preceding and including the.
Diatoms are of great significance to primary productivity in oceans, yet little is known about their biogeographic distribution in oligotrophic rivers. With the help of metabarcoding analysis of 279 samples from the Yangtze River, we provided the first integral biogeographic pattern of planktonic and benthic diatoms over a 6030 km continuum along the world’s third largest river.

The 17-propionate ester group of chlorophyll(Chl)-a in some oxygenic phototrophs was investigated using HPLC. Chls-a esterified with partially dehydrogenated forms of a phytyl group were found in fully grown cells of a diatom, Chaetoceros calcitrans: geranylgeranyl (GG), dihydrogeranylgeranyl (DHGG), and tetrahydrogeranylgeranyl (THGG).
Chloromethane, also called methyl chloride, R-40 or HCC 40, is a chemical compound of the group of organic compounds called haloalkanes.It was once widely used as a refrigerant.It is a colorless extremely flammable gas with a mildly sweet odor, which is, however, detected at possibly toxic levels.
However, a classification built only on shapes and on main morphological traits may capture many of the functional properties of phytoplankton, as shown by studies carried out comparing different typologies of freshwater and marine ecosystems (Finkel et al., 2010; Kruk et al., 2010; Naselli Flores and Barone, 2011; Kruk and Segura, 2012; Roselli and Basset, 2015).
Chaetoceros calcitrans, Nannochloropsis salina, and Pavlova sp. were chosen as thealgae sources as they have potentially high use in. 4 biodiesel production due to high lipid content and each their as been included inh. 1.8.1 Taxonomic Classification.
The impact of diets upon the fatty acid composition of haemocyte polar lipids and consequently upon immune parameters has been tested in the oyster Crassostrea gigas and the clam Ruditapes philippinarum. Oysters and clams were fed each of three cultured algae: Chaetoceros calcitrans, which is rich in 20:5(n-3) and 20:4(n-6) and poor in 22:6(n-3) fatty acids; T- Iso ( Isochrysis sp.), which.
In many areas of the world’s ocean such as the Southern Ocean (SO), primary production is low despite an abundance of macronutrients. In these high nutrient low chlorophyll (HNLC) regions the trace metal (TM) iron (Fe) limits phytoplankton biomass and subsequently the biological carbon pump. Besides Fe, the TMs zinc (Zn), cobalt (Co), and the vitamin cobalamin (B12) have also been shown to.
