“…These results can be explained by changes in the perception capacity of the food in the medium, as well as the morphophysiological characteristics of larvae during development. Throughout development, larvae of species of Macrobrachium develop mouthparts (Rocha et al, 2016(Rocha et al, , 2018, antennules, endopodites with chemoreceptors of smell and touch (Ache, 1982). With the development of these structures, mechanoreception ceases to be the main mechanism to distinguish the presence of food in the environment.…”

Food acceptance in different larval stages of Macrobrachium carcinus was evaluated by investigating the stage at which the ingestion of inert moist diet food begins and by the incidence of Artemia nauplii and inert moist diet in the digestive tract throughout development. Two experiments were carried out: in the first study, the acceptance of the inert diet was evaluated in 60 larvae of each stage (I to XII) fed ad libitum after two hours of fasting. The inert diet was 100% accepted at zoea stage V. In the second study, newly hatched larva was then kept in larval tanks and fed with Artemia nauplii and inert moist diet simultaneously. Fifteen minutes after feeding, 50 specimens of each larval stage were examined and evaluated for the ingestion of these foods. Larvae at stage I did not feed, while larvae at stage II consumed both live and inert food. From the stage of zoea IX, the exclusive consumption of Artemia nauplii was not verified. These data indicate that feeding M. carcinus in larviculture can be initiated at stage II with inert moist diet and Artemia nauplii, and an exclusive supply of inert moist diet from stage IX can be recommended.

“…Schuh & Diesel (1995) e Anger (1995), em estudos com o caranguejo Sesarma curacaoense (Sesarmidae),demonstraram que a alimentação de zoés I, mesmo quando lecitotróficas, pode diminuir a duração do estádio e maximizar a sobrevivência nos estádio seguintes. Já Anger & Hayd (2010), em estudo com larvas de M. amazonicume Rocha et al (2016)com M. jelskii, demonstraram que não há alteração de duração da zoé I, independente da presença ou não de alimentação. Cabe ressaltar, que estas espéciestêm desenvolvimento mais rápido e abreviado em comparação com M. olfersii.…”

SÉRGIO LUIZ COSTA BONECKER RESUMOA maioria dos crustáceos decápodes, incluindo os camarões Macrobrachium acanthurus e Macrobrachium olfersii, têm fase larval planctônica no início da vida. As larvas enfrentam diversos estresses ambientais, sendo um dos principais a obtenção de alimentos. A inanição, ou privação de alimentos, pode gerar atrasos no desenvolvimento e incremento da mortalidade larval. Sendo assim, o presente estudo teve como objetivo analisar os efeitos de períodos iniciais de inanição no desenvolvimento larval dos camarões M. acanthurus e M. olfersii. Fêmeas ovígeras foram coletadas no Rio Sahy, Mangaratiba (RJ, Brasil), sendo mantidas em temperatura constante de 25,0 ± 0,5°C. Após a eclosão, as larvas de cada espécie foram submetidas a diferentes tratamentos, sendo: 1. Alimentação diá-ria desde o nascimento, 2. Inanição permanente e 3. Inanição inicial de três a 10 dias, seguida de alimentação diária. As larvas de ambas as espécies chegaram ao estádio zoé II, mesmo sem alimentação. A ausência de alimentação não afetou a duração da zoé I de M. acanthurus, mas aumentou em um ou dois dias a duraRevista Semioses, V 11, n.02, 2017 STARVATION EFFECTS IN EARLY LARVAL STAGES OF THE PRAWNS ABSTRACTMost decapod crustaceans, including the prawns Macrobrachium acanthurus and Macrobrachium olfersii, have planktonic larval phase at their life beginning.

“…Studies of the functionality of the digestive system of freshwater prawns have found considerable variation in the duration of the ontogenetic development of the larva, which may be prolonged, abbreviated or partially abbreviated (Magalhães & Walker, 1988). Up to the present time, however, this process has been investigated in detail in only two long-cycle palaemonid species of the Macrobrachium Bate, 1868 – M. rosenbergii and M. amazonicum (Abrunhosa & Melo, 2002; Queiroz et al , 2011) and only one with abbreviated development, M. jelskii (Rocha et al , 2016). The initial larval stages of the M. jelskii (stages I and II) and first stage of M. amazonicum have undeveloped external mouthparts, a lack of setae, and structureless foregut, all of which indicate the lack of functionality for feeding (Queiroz et al ., 2011).…”

“…The comparative morphology of the feeding appendages and foregut during different stages is expected to provide important information for understanding the appropriate nutrients for each larval stage or the feasibility of an initial no-feeding period in the case of a non-feeding larval stage (Abrunhosa, 1997; Abrunhosa & Kittaka, 1997a; Rocha et al , 2016). Unnecessary addition of feed to rearing tanks may even reduce productivity, given that the introduction of live food, such as Artemia nauplii, may result in a deterioration in water quality, which may eventually affect the wellbeing of the larvae (Abrunhosa & Kittaka, 1997b).…”

The present study describes the morphological changes of the mouthparts and foregut of the freshwater prawn M. acanthurus that occur during the development of the larvae and first juvenile. The results indicate that the zoeae I have mouthparts with reduced setae and a structureless foregut that indicates obligatory lecithotrophic behaviour. There is an increase in the number of setae in these structures between the zoea II and the juvenile stage, indicating the adaptation of the organism for feeding. More complex structural alterations were observed in the first juvenile, which acquires benthonic habits, which ensure the capture and ingestion of a diversity of feeding resources found in the substrate.
