“…In this study, the scalloped spiny lobster exhibited optimal WGR and SGR under 12 L:12 D. Although no significant difference was observed in WGR and SGR between long (>12 L) and short (<12 L) photoperiods, lobsters under longer photoperiods showed higher growth rates, suggesting that extended light periods may more effectively promote growth in aquatic animals. This finding aligns with observations in other species, including larval coconut crabs (Birgus latro) [57], mud crabs [21], narrow-clawed crayfish (Astacus leptodactylus) [46], blue swimming crab (Portunus pelagicus) [58], and juvenile winter flounder (Pseudopleuronectes americanus) [59]. Contrarily, horsehair crab (Erimacrus isenbeckii) larvae showed optimal survival and growth under continuous darkness (0 L:24 D) [60].…”

This study aimed to elucidate the effects of different photoperiods (0 L:24 D, 6 L:18 D, 12 L:12 D, 18 L:6 D, 24 L:0 D, “Light (L) and Dark (D)”) on the growth performance and physiological responses of the juvenile scalloped spiny lobster (Panulirus homarus). Over a period of 56 days, parameters such as growth rate, digestive enzyme, immune enzyme, and antioxidant enzyme were meticulously evaluated in 90 lobsters subjected to these varying light conditions. The present study found no significant differences in survival rate (SR), molting frequency (MF), and meat yield production (MYP) among the various photoperiod treatments (p > 0.05). Notably, the highest weight gain rate (WGR) and specific growth rate (SGR) were observed under a 12 L:12 D photoperiod. In the continuous dark phase (0 L:24 D), pepsin (PEP) activity remained high in gastric tissues, while trypsin (TRYP) and chymotrypsin (CHT) activities reached the highest in hepatopancreas tissues. The α-amylase (AMS) activity in the hepatopancreas was most elevated under 18 L:6 D, and the optimal lipase (LPS) activity was recorded under 12 L:12 D. The activity of acid phosphatase (ACP) in the hepatopancreas was highest in the absence of light (0 L:24 D), whereas the activities of alkaline phosphatase (AKP) and lysozyme (LZM) were most effective under the 12 L:12 D photoperiod. The total antioxidant capacity (T-AOC), along with catalase (CAT) and superoxide dismutase (SOD) activities of the hepatopancreas reached the highest at 12 L:12 D. The highest activity of glutathione peroxidase (GSH-Px) was seen under 18 L:6 D. The concentration of malondialdehyde (MDA), a marker of oxidative stress, was found to be highest under 12 L:12 D. Consequently, this specific photoperiod is essential for achieving optimal growth and maintaining appropriate physiological balance in the scalloped spiny lobster during aquaculture. These findings provide a foundational guideline for establishing the lighting environment in the farming of the juvenile scalloped spiny lobster.

“…Broodstock and larval rearing protocols followed those developed in our lab (Butts et al, 2015; Butts & Litvak, 2007a, 2007b; Litvak, 1999; Litvak et al, 2020). We generated juveniles for this experiment by rearing larvae under 24 hr light (Litvak et al, 2020). Young‐of‐the‐year winter flounder juveniles were reared in the laboratory and exposed to three temperatures (±0.5°C): 10, 15, and 20°C.…”

“…The development of culture techniques suitable for this species has been ongoing for many years (Fairchild, 2010; Litvak, 1999). Larval rearing protocols have already been successfully developed (Ben Khemis, Audet, Fournier, & De La Noüe, 2003; Ben Khemis, De La Noue, & Audet, 2000; Litvak, 1999; Litvak, Zadmajid, & Butts, 2020; Martinez‐Silva, Audet, Winkler, & Tremblay, 2018) and metamorphosed fish can be weaned onto formulated diets (Bélanger et al, 2018; Butts, Ben Khemis, & Litvak, 2015; Fairchild, Rennels, Howell, & Wells, 2007; Lee & Litvak, 1996a, 1996b). However, postmetamorphic mortality rate of winter flounder reared in the hatchery is still high and pigmentation of juveniles can be poorly developed.…”

Winter flounder, Pseudopleuronectes americanus, has emerged as a promising candidate flatfish for cold‐water aquaculture and restocking. Here, juveniles were reared for 8 weeks at three temperatures: 10, 15, and 20°C under 24‐hr light. All fish were imaged at stocking and at 2‐week intervals, where growth was measured as changes in standard length (SL) and body area (BA). By week 2, fish reared at 15 and 20°C were larger than those grown at 10°C. At weeks 4 to 6, fish at 15°C were larger than fish at 20°C. Linear regressions were used to model growth dynamics over time at each temperature. Highly significant linear growth trajectories were detected over time for SL and BA. SL and BA regressions also showed a significant difference among the slopes across temperatures, where comparing slopes showed the best temperature to rear the flounder was 15°C. Weights of fish held at 15°C and 20°C were greater than at 10°C at the termination of the experiment. Within each temperature, the growth rate of malpigmented fish was not different from that of the normally pigmented fish. Overall, growth of winter flounder was comparable to that of other commercially produced flatfish species, providing strong evidence for this flatfish species as a potential species for aquaculture.

“…El fotoperiodo puede ser uno de los factores externos más críticos en la ontogenia temprana de los peces; así como, una de las variables controlables más importantes en la cría de las larvas (Kamler 2002, Abdollahpor et al 2020. Afecta la eclosión, la actividad alimenticia, el crecimiento, comportamiento, metabolismo, sistema inmune, malformaciones y supervivencia de las larvas de peces (Sánchez-Vázquez y López-Olmeda 2018, Litvak et al 2020, Ma et al 2021. La mayoría de las larvas de peces marinos son depredadores visuales y dependen de la fotorrecepción para determinar la ubicación de las presas, por lo que necesitan luz para poder alimentarse (Villamizar et al 2013, Hu et al 2018.…”

En el presente trabajo se evaluó el efecto de diferentes fotoperiodos en la eclosión, crecimiento y supervivencia de larvas de Sphoeroides annulatus. En cada uno de 12 tanques de fibra de vidrio se colocaron 5 g de huevos desgomados y se evaluó la tasa de eclosión, crecimiento en longitud total peso y supervivencia de las larvas bajo cuatro fotoperiodos con tres replicados cada uno: 24 horas luz (hl), 18 hl, 12 hl y 0 hl, durante 45 días después de la eclosión. La tasa de eclosión fue significativamente menor a 0 hl y las larvas no sobrevivieron a los5 días después de la eclosión. El crecimiento, tanto en longitud como peso, fue significativamente mayor a 12 hl. La supervivencia no presentódiferencias significativas entre los tratamientos. Los resultados sugieren que el fotoperiodo afecta la tasa de eclosión y el crecimiento de las larvas de S.annulatus, bajo las condiciones del presente estudio.
