Postembryonic development of Pyromaia tuberculata (Lockington, 1877): a review of larval and postlarval morphology

Scientia Marina, 2003
The spider crab Pyromaia tuberculata (Lockington, 1877) (Decapoda, Majidae) has been recorded from eastern Pacific coasts (México to Colombia), the western Pacific (Japan and New Zealand) and the western Atlantic (southern Brazil, near Rio de la Plata ...

Rearing enhancement of Ovalipes trimaculatus (Crustacea: Portunidae) zoea I by feeding on Artemia persimilis nauplii enriched with alternative microalgal diets

Scientific Reports, 2020
The southern surf crab Ovalipes trimaculatus (de Haan, 1833) presents a high potential for aquaculture. In this study, we analyze the benefits of different dietary treatments on its molt success and fitness of larval stages.

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 ...

The oldest “intermetamorphic” larva of an achelatan lobster from the Lower Jurassic Posidonia Shale, South Germany [PDF]

Acta Palaeontologica Polonica, 2019
Achelatan lobsters, also known as spiny and slipper lobsters, develop via a highly specialised larval form. This special larva, phyllosoma, is flat, translucent, possesses elongate legs and can grow to enormous sizes.

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

Tolerance of Hyas araneus zoea I larvae to elevated seawater PCO2 despite elevated metabolic costs [PDF]

, 2012
Early life stages of marine crustaceans respond sensitively to elevated seawater P CO 2 . However, the underlying physiological mechanisms have not been studied well. We therefore investigated the effects of elevated seawater P CO 2 on oxygen consumption,

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.

Larval development of Notolopas brasiliensis Miers, 1886 (Brachyura: Majoidea: Pisidae) described from laboratory reared material and a reappraisal of the characters of Pisidae

Papéis Avulsos de Zoologia, 2006
The complete larval stages of Notolopas brasiliensis are described from laboratory reared material, with emphasis on the external morphological features of Majoidea, and compare the morphology of N. brasiliensis with other genera of Pisidae.

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.
