A new system for the rapid collection of large numbers of developmentally staged zebrafish embryos.

PLoS ONE, 2011
The zebrafish is an excellent genetic and developmental model system used to study biology and disease. While the zebrafish model is associated with high fecundity, its reproductive potential has not been completely realized by scientists.

Annual fecundity, batch fecundity, and oocyte atresia of Atka mackerel (Pleurogrammus monopterygius) in Alaskan waters [PDF]

, 2007
Annual potential fecundity, batch fecundity, and oocyte atresia were estimated for Atka mackerel (Pleurogrammus monopterygius) collected in Alaskan waters during 1993−94.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Reproductive Ecology of the Java Rabbitfish, Siganus javus, in the Southern South China Sea

Fishes
Fish reproductive biology influences their life history and can impact their vulnerability to fisheries; therefore, for sustainable management and development, a proper understanding is crucial. Reproductive biology, including maturation, spawning season,

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

A review of the biology and management of horseshoe crabs, with emphasis on Florida populations [PDF]

, 2007
In Florida, some horseshoe crabs are fished for eel bait, but they are fished principally by the marine-life industry, which collects the animals live for resale as aquarium, research, or educational specimens.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

New insights into the reproductive physiology and culture approaches of Paratilapia sp., a Malagasy cichlid with potential interest for sustainable aquaculture

Journal of the World Aquaculture Society
One of the primary objectives in freshwater aquaculture is the search for sustainable systems based on agroecological intensification. In this context, the cultivation of local species is decisive, although requiring the identification of new candidates.

Reproductive biology of two sympatric species of tooth-carps: Aphanius hormuzensis and Aphanius furcatus, from south of Iran (Teleostei: Aphaniidae)

International Journal of Aquatic Biology, 2018
Some aspects of the reproductive biology of two endemic tooth-carps, Aphanius hormuzensis and A. furcatus, from southern Iran, were studied by regular monthly collections throughout one year. Significant differences were observed between the total number

Movements and spawning of white marlin (Tetrapturus albidus) and blue marlin (Makaira nigricans) off Punta Cana, Dominican Republic [PDF]

, 2005
With a focus on white marlin (Tetrapturus albidus), a concurrent electronic tagging and larval sampling effort was conducted in the vicinity of Mona Passage (off southeast Hispaniola), Dominican Republic, during April and May 2003.
