The morphologies of the cerebral ganglia (brains) of three infraorders of the decapod crustaceans (Astacura-crayfish; Brachyura-crabs; Palinura-spiny lobsters) are described. A common nomenclature is proposed for homologous nerve roots, brain regions, tracts, commissures, neuropils, and cell body clusters.

This study aimed to know the effect of different feedings on growth performance, physiological responses, and behavioral changes juvenile spiny lobsters. The experimental method used a completely randomized design with three treatments four replications. There were feeds as treatment, namely: flesh mussel (K), commercial fish feed (I), shrimp (U). Feed is given much 30% body weight, five times ...

Lobsters have a self-renewing olfactory system and, like many animals, continuously replace old or dying olfactory receptor neurons. In addition, lobsters are able to regenerate the peripheral olfactory system even after complete loss. The olfactory sensors in lobsters are located distally on a pair of antennules. These antennules are often damaged, but this has little impact on the lobster's s...

The availability of cheap and high nutritional value artificial feed is a prerequisite for the sustainability lobster cultivation. In this study, formula was made based on chicken egg hatching waste maggot flour. purpose study to determine performance scalloped spiny lobsters with treatment P1 (70% fish meal + 0% waste), P2 (50% fishmeal 20% P3 (30% 40% P4 (10% 60% hatchery waste). This used se...

In order to determine the potential utility of trace elemental natural tags to resolve fine-scale stock structure and residency patterns in adult crustaceans, we investigated whether concentrations of trace elements in exoskeleton could be used to resolve capture sites of red rock lobsters Jasus edwardsii. Using inductively coupled plasma mass spectrometry, we measured ratios of Li, Mg, Mn, Ba ...

Assessments of the conservation and fisheries effects of marine reserves typically focus on single reserves where sampling occurs over narrow spatiotemporal scales. A strategy for broadening the collection and interpretation of data is collaborative fisheries research (CFR). Here we report results of a CFR program formed in part to test whether reserves at the Santa Barbara Channel Islands, USA...

Most studies of lobster chemoreception have focused on the model systems of Panulirus argus (Palinuridae) and Homarus americanus (Nephropidae). We compare antennule morphology across lobsters and conduct the first kinematic study of antennule flicking in a palinurid species other than P. argus. High-speed video analysis shows that Palinurus elephas flicks at a rate more than an order of magnitu...

Abstract Grow-out of lobster performed in a tank culture system offers several advantages over floating sea cage culture, particularly the control environmental factors. However, growth reared tanks need to be evaluated determine rearing period achieve market size. Growth is defined as change size through molting process. Therefore, this study was assess differences weight and length increment ...
