“…Water temperature was maintained at 7.5 AE 0.5 C and salinity at 32-33 ppt. In accordance with the maximum daily ration recommendations of Epelbaum and Kovatcheva (2005), each developmental stage of larvae were fed twice daily with newly hatched nauplii of Artemia sp. Glaucothoe and juveniles were reared at 10 AE 0.5 C. As red king crab glaucothoe are lecithotrophic (Abrunhosa and Kittaka 1997), they were not fed.…”

Phototactic responses of light-adapted zoeae IV, glaucothoe, and first stage juveniles of the red king crab to three intensities of white light were quantitatively measured under laboratory conditions. All stages observed were photopositive to all light intensities tested, except for late glaucothoe (10 days since moulting) which did not respond to light stimuli. Phototactic response changed in the early life history of the red king crab. The extent of photopositive movement decreased after each metamorphosis. Peak phototactic response in zoea IV were observed at a light intensity of 1.9 Â 10 13 q cm À2 s À1 , in early glaucothoe at 1.1 Â 10 10 q cm À2 s À1 and in juveniles at 1.3 Â 10 9 q cm À2 s À1 . The data on behavioural responses to light may provide a better understanding of the early life history, survival and recruitment of the red king crab and assist the development of feasible methods and techniques for aquaculture of this species.

“…By contrast, food limitations can compromise nutritionally depleted larvae, reducing the survival rate and increasing cannibalism (Jones et al 1997). The relationship between increased larval consumption of Artemia in response to an increase in the density of the latter had been previously observed for larvae of M. rosenbergii (Barros and Valenti 2003), king crab -Paralithodes camtschaticus (Epelbaum and Kovatcheva 2005) and M. amazonicum (Maciel et al 2012). Thus, the success of feeding during larval development depends on the efficient combination of food capture by the larvae and the nutritional quality of the food (Anger 2001).…”

In the present study, we carried out experiments on the diet of the freshwater prawn Macrobrachium equidens. We tested which type of food and which density of food is suitable for larval development. For the experiment on the type of food, eight treatments were carried out: (I) starvation, (AL) microalgae, (RO) rotifers, (AN) Artemia, (RO + AN) rotifers + Artemia, (AL + RO) microalgae + rotifers, (AL + AN) microalgae + Artemia, (AL + RO + AN) microalgae + rotifers + Artemia. For the experiment on the density of food, we used the type of food, which had resulted in a high survival rate in the previous experiment. Three treatments were carried out: 4, 8 and 16 Artemia nauplii /mL. The rate of feeding during larval development was observed. The survival, weight and percentage of juveniles of each feeding experiment were determined. We found that larvae are carnivores; however, they have requirements with respect to the type of food, because larvae completed their cycle from the zoeal to the juvenile stage only when Artemia nauplii were available. We also verified that the larvae feed mainly during the day-time, and are opportunistic with respect to the density of food offered.

“…However, predictions of future rates or southern limits of spread require more information from larval biology, especially on larval temperature tolerance and nutritional requirements, but also on benthic postsettlement ecology of the early juvenile stages (Zaklan, 2002;Epelbaum and Kovatcheva, 2005;Stevens and Swiney, 2005). Benthic interactions, especially those with native predators, are important for the persistence of invasive populations (deRivera et al, 2005).…”

SummaryMany aquatic crustaceans pass through a complex life cycle comprising a benthic juvenile-adult and a pelagic larval phase. In the study of aquatic ecology, meroplanktonic larvae are therefore considered as principal components of benthic-pelagic coupling processes. As a consequence of radical transitions of life style, larvae differ from conspecific adults in their ecology, behaviour, nutrition, morphology, and physiology. Ontogenetic changes of these traits, as well as carry-over effects of larval condition on postmetamorphic fitness of benthic juveniles, are subjects of the interdisciplinary field of larval biology. Larval biology is thus not only an intrinsic part of lifehistory studies, but contributes essential information also to various other biological disciplines, including the broad area of crustacean research. For economically important species, it provides critical information for the development of aquaculture techniques or for the management of sustainable fisheries. Inferring from heritable ontogenetic patterns, comparative studies of larval morphology also aid the identification of phylogenetic relationships within and among higher taxa ("Evo-Devo" perspective). On the other hand, larval traits may be modified by environmental factors, which link larval ecology to developmental biology ("Eco-Devo" approach). Patterns of larval dispersal, mortality, and recruitment are crucial for the stability of benthic populations and communities. These aspects of "supply-side ecology" have also consequences for patterns of biogeographic distribution, population connectivity, genetic diversity, and the formation of metapopulations. In addition, the spread of introduced species in recipient regions may be explained or predicted through developmental and ecophysiological traits of their larvae. In evolutionary biology, knowledge of reproductive and developmental adaptations is crucial for the understanding of limnic and terrestrial invasions by originally marine crustaceans.
