The population dynamics of eight commercial species of shrimp (Haliporoides sibogae, Harpiosquilla harpax, Metapenaeus affinis, Metapenaeus brevicornis, Metapenaeus tenuipes, Parapenaeopsis cultrirostris, Parapenaeopsis gracillima and Parapenaeus maxilipedo) distributed in littoral marine zone of the Mekong Delta were investigated. Length-based stock assessment using FiSAT II software package w...

The activation properties of in situ nematocytes of Pelagia noctiluca (Scyphozoa) were investigated by physical contact with a gelatin probe that, besides stimulating the nematocyte battery, retains the discharged nematocysts, thereby allowing a quantitative evaluation of the response. In oral arms previously treated with 2 mmol l-1 La3+ the discharge was inhibited. This result confirms the Ca(...

Based on length frequency data of miter squid ( Uroteuthis chinensis ) collected in the northeastern South China Sea 1975–1977, 1997–1999, and 2018–2019, asymptotic length, optimal at first capture, relative mortality, biomass stock were estimated using length-based Bayesian estimation (LBB). The LBB-estimated for 2018–2019 was smaller. Optimal lengths capture later far exceeded average catches...
