Aquatic Sealives Grow Lamp (ESH-SEALIVES series)

The Molting or ecdysis in sea-lives (like shrimps or crabs) is considered the most essential process in its development. The shedding of the exoskeleton is a necessary precondition for their growth; without molting, the sea-lives are stunted, and will continue to consume feed without any resulting increase in body weight. In general, studies show that the shrimp and crabs will increase their body size and weight by 5%~20% every time they molt. Therefore, a good control and practice of timely induced molting on ready and healthy sea-lives can increase production and hence the profitability.

The vision of a shrimp/prawn is of particular interest in view of extensive studies of the responses of its chromatophore systems and eye pigments to light. The compound eye is made up to 10,000 separate ommatidia of the opposition type. Some may have at least 16 different photoreceptor types, which are divided into four classes (their spectral sensitivity is further tuned by color filters in the retinas), 12 of them for color analysis in the different wavelengths (four which are sensitive to the ultraviolet light) and 4 for analyzing polarized light.

In numerous studies and researches found by researchers, the maximum photoactic effectiveness of a common prawn was found in the blue-green wavelength, and their spectral sensitivities are 390nm and 540nm (George and Edward, 1968). In addition, there are some experimental evidences to support the contention that not only should shrimp be spawned under low light intensity, but the blue or green light should be used. Further to the described spectral sensitivity researches, studies indicated that continual light conditions have a positive impact on survival of prawn juveniles during the nursery phase. Survival was significantly greater in prawn raised under continual light condition -Light:24H-Dark:0H (72%) than those raised under –Light:12H-Dark:12H (59%) or continual Darkness –Light:0H-Dark:24H (58%).

Real Magic’s researches in the patent pending Light control for timely induced molting, that done in the safe, natural, and economical ways, will be an effective management tool to predict, control, and optimize growth potential in the seal-live species like shrimp or crabs. Our laboratory experiments show significant increase of molting rate up to 150%. The ESH-SEALIVES series is a great Aquaculture product to gain and to increase the farmers’ advantages and benefits in this new bio-technological Light spectrum (with less use of enzymatic formulas). It consists of the important Light of maximum photoactic effectiveness and optimum feed-intake (FI) spectral of Green and Red wavelengths.

We are confident of this patent pending Bio-lamp (ESH-SEALIVES series) in the aquaculture growth product will provide additional advantages to the farmers in the following,

  • Additional tool to control parasites and bacterial infections,
  • Plan, manage, and better control of sea-lives growth (especially shrimp and crabs),
  • Enjoy phenomenal growth rates and shorter culture cycles,
  • High profits at better feed conversion ratios with low feed costs and lower mortality rates,
  • Higher survival rate from the result of continual economical light condition.
