“…However, the so far reported systems are almost all based upon batch cultures of copepods. Only a few continuous cultures have been reported (Støttrup & Norsker ; Buttino, Ianora, Buono, Vitiello, Malzone, Rico, Langellotti, Sansone, Gennari & Miralto ). Regarding water quality in copepod cultures, to our knowledge, only Payne and Rippingale () and Støttrup and Norsker () touch the subject.…”

Tolerance of un-ionized ammonia in live feed cultures of the calanoid copepodAcartia tonsaDana

Optimal water quality is considered as being a restriction for marine copepod cultures for live feed. There is a lack of knowledge on the water‐quality conditions in copepod cultures and the effect on copepods. Few studies have investigated the effect of ammonia on copepods, and fewer reports No Observed Effect Concentrations (NOEC) and Lowest Observed Effect Concentrations (LOEC), which provides safety levels before cultures are affected. This study investigates the tolerance of Acartia tonsa nauplii and adults to ammonia, using mortality as the endpoint after 24, 48 and 72 h of exposure. Nauplii were exposed to levels from 0 to 5127 μg NH3 L−1 and adults to levels from 0 to 8481 μg NH3 L−1. Nauplii NOEC was 30 μg NH3 L−1 and LOEC was 81 μg NH3 L−1. Adult NOEC was 477 μg NH3 L−1 and LOEC was 1789 μg NH3 L−1. 50% Lethal Concentrations (LC50) for nauplii of 48 and 72 h was 1257 and 220 μg NH3 L−1. LC50 for adults was 2370 (24 h), 972 (48 h) and 770 (72 h). Combining NOEC with excretion rates of NH4/NH3 a model was developed to calculate densities in batch cultures. We recommend that for batch cultures of A. tonsa, NH3 is kept below NOEC for nauplii and that levels of NH3 together with pH are monitored weekly.

“…The dinoflagellate Prorocentrum minimum is considered to be a high-quality food item for C. typicus (Calbet et al 2007). In fact, it is currently administered to laboratory cultures of this copepod, inducing high percentages of survivorship (Buttino et al 2012) and viable embryos. It is therefore not surprising that it was recognized by and attracted C. typicus at both the lowest and medium concentrations.…”

Centropages typicus(Crustacea, Copepoda) reacts to volatile compounds produced by planktonic algae

et al. 2015

Volatile organic compounds (VOCs) may play the role of infochemicals and trigger chemotaxis and ecologically relevant responses in freshwater and marine invertebrates. Aquatic grazers use these signals as chemical cues to trace the presence of their food or to detect their predators. However, detailed data are still needed to fully understand the role of these relationships in marine plankton. We investigated the ability of the copepod Centropages typicus to perceive the odour of three planktonic diatoms (Skeletonema marinoi, Pseudonitzschia delicatissima and Chaetoceros affinis) and a dinoflagellate (Prorocentrum minimum). This information is ecologically relevant for orientation, habitat selection, predator avoidance and communication. In addition, as the pH of the medium influences the perception of chemical cues in aquatic environments, we tested the effect of seawater acidification resulting from increasing levels of CO2, and its influences on the olfactory reactions of copepods. For this reason, our tests were repeated in normal (pH 8.10) and acidified (pH 7.76) seawater in order to simulate future ocean acidification scenarios. Using replicated chemokinetic assays we demonstrated that VOCs produced by Ps. delicatissima and Pr. minimum attract copepods at normal pH, but this effect is lowered in acidified water. By contrast, the odour of S. marinoi mainly induces a reaction of repulsion, but in acidified water and at higher concentrations this toxic diatom becomes attractive for copepods. Our experiments demonstrate, for the first time, that copepods are sensitive to the volatile compounds contained in various microalgae; VOCs prompt chemokinesis according to algal species and odour concentrations. However, seawater acidification induces changes in copepods' perception of odours. These findings highlight the sensitivity of chemically mediated interactions to global changes

“…T. stylifera were collected in the Gulf of Naples and returned to the laboratory within 1 h of collection on the first day of experiments. C. helgolandicus were maintained in culture on a mixed diet of Isochrysis galbana, Rhodomonas baltica, and P. minimum (Buttino et al, 2012). T. stylifera had fed on natural plankton assemblages in the Gulf of Naples prior to capture.…”
