Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

Seasonal succession and niche differentiation in Skeletonema species driven by temperature and salinity in inner Tokyo Bay

Journal of Phycology, EarlyView.
Abstract The genus Skeletonema is a dominant diatom in coastal waters worldwide, frequently causing blooms, and it includes several cryptic species. To elucidate the occurrence patterns and niche differentiation among Skeletonema species in Tokyo Bay, Japan, sampling was conducted between June 2021 and February 2023.

Toxic and non-toxic dinoflagellates host distinct bacterial communities in their phycospheres

Communications Earth & Environment, 2023
Dinoflagellates encompass highly abundant and diverse toxin-producing species among marine phytoplankton. Previous works suggested that some bacterial taxa may affect toxins production in dinoflagellates, however, little is known about impact of toxic ...

Simultaneous Effect of Temperature and Irradiance on Growth and Okadaic Acid Production from the Marine Dinoflagellate Prorocentrum belizeanum [PDF]

, 2014
Benthic marine dioflagellate microalgae belonging to the genus Prorocentrum are a major source of okadaic acid (OA), OA analogues and polyketides. However, dinoflagellates produce these valuable toxins and bioactives in tiny quantities, and they grow ...

Variability of planktonic and epiphytic vibrios in a coastal environment affected by Ostreopsis blooms

Scientia Marina, 2016
Vibrios include several pathogenic bacteria that occur in aquatic environments. The presence of Vibrio has been assessed in many ecosystems by culture-based techniques.

Fresh-water dinoflagellates of Maryland [PDF]

, 1947
Collections were made in the summer of 1942 and again at different times in 1946 and 1947. Some collections were not sufficient in numbers to allow for proper identification, so the present paper does not give a complete list.

Comparison of the Functional and Numerical Responses of Resistant versus Non-resistant Populations of the Copepod Acartia Hudsonica Fed the Toxic Dinoflagellate Alexandrium Tamarense [PDF]

, 2007
The functional and numerical responses of grazers are key pieces of information in predicting and modeling predator–prey interactions. It has been demonstrated that exposure to toxic algae can lead to evolved resistance in grazer populations.

Transformation of Phytoplankton Communities in the High Arctic: Ecological Properties of Species

Diversity
During the 84th cruise of the R/V Akademik Mstislav Keldysh in August 2021, patterns of phytoplankton composition transformation were revealed along a northward gradient. The study involved three transects in the Fram Strait and adjacent Arctic waters: a

Description of two species of early branching dinoflagellates, Psammosa pacifica n. g., n. sp. and P. atlantica n. sp. [PDF]

PLoS ONE, 2012
In alveolate evolution, dinoflagellates have developed many unique features, including the cell that has epicone and hypocone, the undulating transverse flagellum. However, it remains unclear how these features evolved.
