“…Because this is an overly complex physiological process, which comprises several stages and phases with a variety of hormones ( Lipcius and Herrnkind, 1982 ; Lachaise et al, 1993 ; Chang, 1995 ; Nakatsuji et al, 2009 ; Chang and Mykles, 2011 ; Mykles, 2011 ; Webster et al, 2012 ), a thorough comprehensive analysis becomes exceedingly difficult. In addition, many environmental factors affect hormone synthesis and secretion, and gene expression, thus strongly influencing the molt cycle ( Guo et al, 2013 ; Stoner et al, 2013 ; Gong et al, 2015 ).…”

Environmental cues synchronize endogenous rhythms of many physiological processes such as hormone synthesis and secretion. Little is known about the diurnal pattern of hormones and gene expression of the Callinectes sapidus molt cycle. We aimed to investigate in the eyestalk and hepatopancreas of premolt and intermolt C. sapidus the following parameters: 1) the diurnal expression of the ecdysteroid receptor CasEcR isoforms, and the molt inhibiting hormone CasMIH; 2) the diurnal hemolymph ecdysteroid and melatonin levels; and 3) melatonin effects on the transcripts of the above-mentioned genes in intermolt C. sapidus. Ecdysteroid levels were higher in the premolt than the intermolt animals at all time points evaluated (ZTs). Premolt crabs displayed a variation of ecdysteroid concentration between time points, with a reduction at ZT17. No difference in the melatonin level was seen in either molt stage or between stages. In the eyestalk of intermolt animals, CasEcR expression oscillated, with a peak at ZT9, and premolt crabs have a reduction at ZT9; CasMIH transcripts did not vary along 24 h in either molt stage. Moreover, the evaluated eyestalk genes were more expressed at ZT9 in the intermolt than the premolt crabs. In the hepatopancreas, CasEcR expression showed a peak at ZT9 in premolt crabs. Exogenous melatonin (10−7 mol/animal) reduced the expression of both genes in the eyestalk at ZT17. In the hepatopancreas, melatonin markedly increased the expression of the CasEcR gene at ZT9. Taken altogether, our results are pioneer in demonstrating the daily oscillation of gene expression associated to molt cycle stages, as well as the daily ecdysteroid and melatonin levels and the remarkable influence of melatonin on the molt cycle of C. sapidus.

“…Most aquatic animals cannot grow without adequate light and food, such as Oreochromis mossambicus , Litopenaeus vannamei , Scylla paramamosain and Icralurus puncrarus (Guo et al, 2013; Konkal & Ganesh, 2018; Liao et al, 2022; Lr & Robinson, 2005; Zhao et al, 2015). Improper light can cause aquatic organisms stunting and even death (Woolley et al, 2014).…”

The saltwater hard clam Meretrix meretrix is an important commercially bivalve in China. Therefore, identification of key genes involved in growth regulation are the primary prerequisites for further development of phenotype-selective breeding of the clams and understanding molecular mechanisms of growth regulation. In the present study, we cloned the full-length cDNA sequences of the growth-related genes cyclindependent kinase 1 and 7 in M. meretrix (MmCDK1 and MmCDK7) and then investi-

“…In aquaculture light, can to be a critical environmental parameter, especially in intensive farming, which uses tanks under covered housing and relies on artificial light (Valenti et al 2010;Guo et al 2011;Guo et al 2012;Utne-Palm et al 2018). Hence, for crustaceans, several studies have investigated the light conditions and found significant differences in their behavior, nutrition, molting frequency, and growth of animals (Guo et al 2012;Guo et al 2013;Jaski et al 2014).…”

This study aimed to investigate the effects of red, yellow, green, violet, blue, and white light in Macrobrachium amazonicum larviculture. The trials were composed of six treatments (i.e., colors red, yellow, green, blue, violet, and white light in tanks) with four replicates each. Transparent tanks of 1 L of water, 10 salinity, and 2400 newly hatched larvae were used in trials. The larvae were fed Artemia salina nauplii and complemented with commercial shrimp feed daily. The light color affected the temperature, pH, and dissolved oxygen in the water culture and nauplii consumption, survival, and productivity of M. amazonicum. In the tanks with red light, the mean temperature was lower, while the oxygen and pH levels were higher than those with other colors. The mean consumption of A. salina nauplii was 15% higher by M. amazonicum in tanks with blue and violet light than red light. No difference in larval development was observed; however, larvae cultured under white light completed the larval cycle four days earlier than those cultured under red light. The productivity of larvae cultivated under white and violet light was 45% greater than larvae cultured under red light, and the survival was > 75%. Results indicated that M. amazonicum larval cultivation should be performed in tanks under bright light, preferably white, since other colors may negatively affect the larval development.
