Operasi penangkapan lobster di Indonesia masih dilakukan dengan cara yang cenderung tidak ramah lingkungan. Penggunaan jaring insang dasar dan krendet mendominasi pada upaya dinilai kurang selektif berpotensi mengakibatkan ghost fishing. Hal ini karena perairan didominasi substrat berpasir, berkarang berbatu membuat sering tersangkut saat diangkat akan ada bagian badan tertinggal. Jaring tertin...

The European lobster, Hommarus gammarus, is a commercially important species in Europe. Despite successful stock enhancement programs during the last two decades, culture methods of H. gammarus are still progress. In this study, effects pseudo-green water technique and clear with lower stocking densities on growth survival larvae stages I-IV were investigated. All reared 800 L cylindro-conical ...

The North Atlantic right whale is one of the most critically endangered marine species. Drastic overexploitation has driven this large, slow-swimming baleen whale to virtual extinction in Europe, while a small remnant population of ~350 individuals remains on the US and Canadian east coast. Although this species has been protected for 70 years, recovery has been slight and extinction is still l...

We have previously shown that lobster olfactory receptor neurons (ORNs) express an odorant-suppressible Cl(-) conductance that modulates the output of the cells. Here, we develop a more complete pharmacological profile of this conductance, showing it is blockable by the Cl(-) channel blockers DIDS, 9-AC and flufenamic acid, but not by niflumic acid. We then show that a conductance with this pha...

Odors activate lobster olfactory receptor neurons (ORNs) through phosphoinositide signaling that appears to target a Na(+)-gated nonselective cation channel. The Na(+)-gated channel is a potential member of the growing family of transient receptor potential (TRP) channels. Here, we test the effect of potential antagonists on the channel in cell-free patches from cultured lobster ORNs. We show t...

First stage larva of the lobster shrimp Allaxius princeps (Boas, 1880) (Decapoda: Axiidea: Axiidae) obtained from the ovigerous female is described and illustrated for the first time. It is the first description of the larva of lobster shrimp from West Pacific. Zoea I of A. princeps is characterized by the presence of four dorsal spines on the pleonal somites 2–5 and by the shape of the telson ...
