Survival of larvae of mud crab, Scylla serrata (Forsskal, 1775) is a persistent issue in the field of induced breeding of the species. A preliminary study was conducted on feeding regimes of laboratory reared larvae and juveniles of S. serrata. The results showed that the survival of the larvae fed with green water alone or green water with plankton and feed was not significantly different from...

This study aims to measure the effect of toxic aqueous solutions of metals on the mobility of Artemia salina nauplii by using digital image processing. The instrument consists of a camera with a macro lens, a dark chamber, a light source and a laptop computer. Four nauplii were inserted into a macro cuvette, which contained copper, cadmium, iron and zinc ions at various concentrations. The naup...

Size-dependent mortality influences the recolonization success of juvenile corals transplanted for reef restoration and assisting juvenile corals attain a refuge size would thus improve post-transplantation survivorship. To explore colony size augmentation strategies, recruits of the scleractinian coral Pocillopora damicornis were fed with live Artemia salina nauplii twice a week for 24 weeks i...

the present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of indian white shrimp post-larvae. four hundred and fifty indian white shrimp post-larvae (pl1) were stocked in nine tanks. the tanks were assigned into three treatments: feeding with inulin-treated (110 mg l-1) artemia nauplii (i-t), feeding with inulin-enri...

We examined anti-predation strategies in relation to motility patterns for early and late nauplii of 6 species of copepods (Calanus helgolandicus, Centropages typicus, Eurytemora affinis, Euterpina acutifrons, Acartia tonsa and Temora longicornis). Remote detection and escape abilities were quantified in siphon flows. Nauplii respond with distinct escape jumps at speciesand stagespecific averag...

Toxic attributes of the brown tide alga Aureococcus anophagefferens affect the ability of benthic and protistan grazers to control blooms. Yet, little is known regarding the effect of A. anophagefferens on a dominant component of the microzooplankton community, copepod nauplii. This study describes the grazer–prey relationship between nauplii of the calanoid copepod Acartia tonsa and A. anophag...

A short-term Tisbe battagliai toxicity test design was used to assess the potential ecological effects of pollutants in coastal marine communities. By exposing nauplii and reproductive females over 4 and 6 d, respectively, to 3 toxic substances (fluoranthene, cypermethin and deltamethrin), the bioassay was seen to successfully measure survival effects on egg, nauplii and adults and sublethal ef...

Copepod nauplii move in a world dominated by viscosity. Their swimming-by-jumping propulsion mode, with alternating power and recovery strokes of three pairs of cephalic appendages, is fundamentally different from the way other microplankters move. Protozoans move using cilia or flagella, and copepodites are equipped with highly specialized swimming legs. In some species the nauplius may also p...

Artemia has been widely used in aquaculture as a suitable live food. The presence of highly unsaturated fatty acids is a key factor that determines the nutritional value and marketing of Artemia for shrimp, marine larvae, sturgeon and ornamental fish industries. To determine the variation in nutritional content in cysts, decapsulated cysts and nauplii of Artemia from three different biotopes of...

This study focuses on how prey behavior may affect predation risk through encounter rates and the escape success of the prey given an encounter. Temora longicornis nauplii require stronger hydrodynamic signals to elicit escape than Acartia tonsa nauplii (critical fluid deformation rates, ∆* of 2.8 to 4.0 and 1.2 to 2.5 s–1, respectively) suggesting that T. longicornis may be more susceptible to...
