“…(2018), L. boggessi larvae hatch with ~10–20% of the yolk distributed in the cephalothorax, that may justify the independence of exogenous food during the early larval stages. The same occurs with L. vittata larvae, which hatch without macroscopically visible yolk reserves, indicating that the yolk must be mostly consumed during the embryonic development (Alves et al ., 2019), and L. ankeri , which larvae hatch only with small visible droplets of yolk (Costa et al ., 2021). Thus, this result also corroborates with larvae of L. boggessi Rhyne and Lin, 2006 by Calado et al .…”

“…According to Almeida et al (2023) a longer larval development is expected for this species, with about nine to 11 larval stages. However, with regard to culture for this species, little information is available in the literature, such as reproductive cycle and embryonic development (Costa et al, 2021) and the importance of light and larval morphology in the starvation of newly hatched shrimps (Calado et al, 2008b). Other information is needed to help in the development of technologies for the culture of these species in the laboratory because most of the time, these ornamental crustaceans are obtained directly from the wild, in an unsustainable way, for the ornamental trade.…”

“…However, the aim of the present study was to determine the nutritional vulnerability in early larval stages of ornamental shrimp L. ankeri, exposed to different periods of starvation or feeding. Considering that the first zoeal stage of L. ankeri hatches with some yolk droplets (Costa et al ., 2021), here, we expect that (1) larvae would tolerate periods of starvation and retain the ability to moult to the next stage (i.e., high PNR value and low PRS value); (2) higher survival rates; (3) higher carapace length (in mm) and shorter development time (in days); (4) there would be a low NVI value (i.e., low dependence on exogenous food).…”

The evaluation of the effects of early starvation and feeding on survival and growth in the early stages of the life cycle of ornamental marine caridean shrimp species is fundamental to establish adequate feeding protocols in their culture. In this study, we determine the nutritional vulnerability in the early larval stages of ornamental shrimp Lysmata ankeri exposed to different periods of starvation or feeding. The larvae were separated into three groups (zoea I-ZI, zoea II with ZI fed, and zoea II with ZI unfed) and subjected to two experiments: (1) point-of-no-return (PNR), comprising one or two days of initial starvation followed by feeding; and (2) point-of-reserve-saturation (PRS), comprising one or two days of initial feeding followed by starvation. Each experiment was still composed of two control groups: continuous feeding and continuous starvation. Larvae tolerated some periods of starvation, with a high PNR value (2.00) and low PRS (0.50). Longer periods of starvation influenced both growth and survival rates in zoea II stages. The nutritional vulnerability index for zoea I was 0.25, which represents a low dependence on food supply. In this study, it was observed that ornamental shrimp L. ankeri larvae hatch with energy reserves, presenting facultative primary lecithotrophy, in which they are able to moult from zoea I to zoea II using such reserves in the absence of food. In this sense, the early larvae stages (zoeas I and II) can tolerate a certain period of starvation, indicating the great potential of this species for aquaculture.

“…To protect the wild population and meet market needs, investigating the artificial breeding of P. trituberculatus is necessary. In general, the ovarian maturation process is a critical period for successful aquaculture, including for the crustacea [4,5]. Since the function of the mature ovary is to produce and periodically release oocytes, the quality of the mature ovary as well as its oocytes directly determines the development of a fertilized egg, which in turn affects the production of crustacea [4,5].…”

The swimming crab Portunus trituberculatus is one of the most important economic species in China and its mature ovary often determines its commercial value and production. Although the ovary maturation of crustaceans is generally affected by exogenous nutrition, the specific nutritional needs of ovary maturation of P. trituberculatus are poorly understood. To this end, we collected the P. trituberculatus samples with five ovarian maturation stages and measured their biochemical composition of the ovary, hepatopancreas, and muscle at each ovarian developmental stage. We further analyzed their relation to the ovarian developmental stage of P. trituberculatus by principal components analysis (PCA). We found the levels of branched-chain amino acids, long-chain polyunsaturated fatty acids (LC-PUFA), and monounsaturated fatty acids (MUFAs) in the ovary and hepatopancreas increased during the ovary maturation process, and also passively correlated with ovarian developmental stage, which highlights the necessity of these specific nutrients for oogenesis and for improving the nutrient quality of crabs. In addition, we found an increasing tendency of carotenoid content and phosphatidylcholine in phospholipid in the ovary from the pre-developmental stage to the proliferative stage, but not in the hepatopancreas and muscle, which highlights the possible involvement of carotenoids during the rapid oocyte development process. Our study may provide valuable information for developing a suitable broodstock diet that promotes the ovarian maturation of adult P. trituberculatus and ensures high-quality larval production.
