“…The nutritional value of crustacean muscle tissue depends not only on the protein content, but also on the protein composition and the amino acid content. A previous study on Portunus trituberculatus found that the essential amino acid content of muscle was positively correlated with dietary protein level (Jin et al., ). The results of the present study also showed increases in WTAA and WEAA with increasing dietary protein content.…”

The optimal protein level in the diet of Oriental river prawn was investigated. Four isocaloric diets containing 300 g/kg, 360 g/kg, 420 g/kg, 480 g/kg crude protein (casein) were tested. Prawns fed 420 g/kg or 480 g/kg protein exhibited higher weight gain, specific growth rate, hepatopancreas somatic indices, feed coefficient and survival rate. Trypsin activity in the hepatopancreas increased with increasing dietary protein, with no significant difference between 420 g/kg and 480 g/kg groups (p < 0.05). Amylase, lipase and cellulase levels were comparable between groups (p > 0.05). Crude protein content in muscle increased with increasing dietary protein, with no significant difference between 420 g/kg and 480 g/kg diets (p > 0.05). There were no significant differences in moisture, crude fat or crude ash between groups. Essential amino acids lysine, tryptophan, phenylalanine, threonine, isoleucine, leucine and valine increased with increasing dietary protein, with no significant difference between 420 g/kg and 480 g/kg groups (p > 0.05). Total and essential amino acids increased with increasing dietary protein. Cloning of the full‐length 2,435 bp Macrobrachium nipponense chitin deacetylase 1 (MnCDA1)gene revealed an open reading frame of 1,632 bp encoding a 535 residue polypeptide qPCR revealed highest expression in the hepatopancreas, followed by muscle, gill, heart and eyestalk. Expression in hepatopancreas and gill tissue, but not muscle, increased gradually with increasing dietary protein.

“…Moreover, fish meal is in high demand as the principal protein source for many formulated diets. However, the annual fish meal production is almost constant, while the demand for fish meal is growing fast, which exerted pressure on fishery stocks and caused the price of fish meal to increase (Jin et al, 2013). The search for fish meal substitutes and alternative dietary protein sources has become an international research priority (Lee, 2002).…”

“…It is widely distributed in the coastal waters of China, Korea and Japan, in sandy or pebble-covered seafloor habitats (Jin et al, 2013). Because of its resilience to handling, rapid growth, delicious meat and high market price, swimming crab production in 2012 has reached up to 99,580 tons (China Fishery Statistical Yearbook, 2013).…”

“…Because of its resilience to handling, rapid growth, delicious meat and high market price, swimming crab production in 2012 has reached up to 99,580 tons (China Fishery Statistical Yearbook, 2013). Till now, only a few studies have been undertaken on the nutrient requirements of the swimming crab (Duan et al, 2011;Jin et al, 2013;Huo et al, 2014). To our knowledge, no research has been reported concerning the lysine requirement of swimming crab.…”

“…This species is the basis of an economically important fishery with global production of 429 959 t in 2012 (FAO ). Seed production is conducted in hatcheries throughout Asia to produce juvenile crabs for stock enhancement and aquaculture (Hamasaki, Obata, Dan & Kitada ; Jin, Zhou, Zhang, Xie, Shentu & Huang ; Lee, Lee, Yoon, Kim, Kim, Hyun, Min & Chung ; Liu, Sun & Hurtado ). However, survival to the juvenile stage has been variable and low because of frequent mass mortality of larvae (Hamasaki et al .…”

Abnormal morphology in megalopae of the swimming crab,Portunus trituberculatusduring seed production: causes and prevention

The occurrence of morphologically immature megalopae, which retain zoeal features such as dorsal spines and furcae of telson, is closely correlated with larval mass mortality during seed production of the swimming crab Portunus trituberculatus in Japanese hatcheries. To determine the cause of immature megalopal morphology, zoeae were reared with various supplementary schedules and density of diets (rotifer, Artemia and phytoplanktons including Chlorella vulgaris and Nannochloropsis oculata). In addition, to assess the relationship between immature morphology and endocrine control, the effect of causative dietary factor was compared with the effect of eyestalk ablation at various timing during zoeal development. Megalopal immature morphology was more distinct in Chlorella‐supplemented groups than in Nannochloropsis‐supplemented groups. High density Chlorella supplementation was associated with the highest incidence of immaturity and resulted in larval mass mortality. The premoult of the third zoeal stage was identified as a critical period at which Chlorella supplementation led to the highest incidence of immaturity. This critical period coincided with the critical period at which larval metamorphosis was regulated by the eyestalk neurosecretory system. Our results suggested that the occurrence of immature megalopal morphology under culture conditions is most likely caused by phytoplankton (especially, Chlorella) supplementation, which disrupts the endocrine regulation. On the basis of our results, we successfully prevented the occurrence of immature megalopal morphology in 500 L tanks by excluding the influence of phytoplankton before the critical period (i.e. discontinuing phytoplankton supplementation and supplying rotifer cultured with non‐phytoplankton materials).
