Las Bolitas Syndrome in Penaeus vannamei Hatcheries in Latin America

Microorganisms
In September 2023, several hatcheries in Latin America experienced significant mortality rates, up to 90%, in zoea stage 2 of Penaeus vannamei. Observations of fresh mounts revealed structures resembling lipid droplets, similar to those seen in a ...

Maternal influence on the larval morphometry of the brush-clawed shore crab Hemigrapsus takanoi (Decapoda: Brachyura)

Scientia Marina, 2023
The morphology of larvae is a key factor influencing their behaviour, performance and ultimately their survival. There is evidence indicating a significant morphological variability among broods, and that this may be related to the size or conditions of

First Zoea of Chasmagnathus convexus (Decapoda: Brachyura: Varunidae) Hatched in the Laboratory [PDF]

Korean Journal of Systematic Zoology, 2007
First zoea of cyclograpsinine crab Chasmagnathus convexus (De Haan, 1835) belonging to the family Varunidae, is described and illustrated in detail based on laboratory-hatched material from an ovigerous female collected in Seumjingang river mouth, southern Korea, Morphological comparison is made with previous description of C. convexus from Japan.

Morphological description of the first zoea of the freshwater shrimp Macrobrachium crenulatum (Decapoda: Palaemonidae) and a comparison to its congeners in the Neotropics

Revista Mexicana de Biodiversidad
We present the first description of Zoea I of Macrobrachium crenulatum and compare it with available data of other zoeae of Macrobrachium spp. of the Neotropics to identify morphological characteristics to differentiate the first zoea of M.

Effect of Salinities and Dietary Patterns toward Fullness of Gut and Gut Evacuation Time of the Newly Introduced Penaeus merguiensis Larvae

Ilmu Kelautan, 2021
The gut capacity of shrimp larvae is minimal, and their digestion is often challenged by the inevitable fact that they tend to develop slowly during the zoea stage.
