“…In experiments by other authors (Mukai & Lim 2014), Lates calcarifer larvae aged from 13 to 26 days had a similar survival rate and growth at 10–1000 lx, but a slightly higher survival rate and the highest mass gain was obtained when lighting reservoirs with illumination at the level of 100 lx. Short growing times (5 and 13 cenjr) and a small volume of reservoir (5 L) may have affected the results.…”

Being one of the main environmental factors, the light factor influences many aspects of animal life. Photoperiod, light intensity (illumination) and wavelength are the primary periodic factors. There is a review that discusses the role of illumination on various life processes of aquatic anamnia vertebrates (fish and amphibians). The effect of light on the development, growth, respiration, consumption and efficiency of food conversion, hormone release, reproduction and behaviour of fish and amphibians has been studied. Illumination influences differently a significant number of physiological and biochemical processes and reactions of anamnia vertebrates at various development stages. The obtained results show that the nature of exposure to light is species-specific and corresponds to the ecological niche of species. Illumination influences both positively and negatively the development, growth and other physiological processes of fish and amphibians. Illumination plays a special role during the first feeding of fish in the environment and aquaculture. There are positive and negative behavioural responses of fish to light. However, it is not always possible to distinguish fish species with only a negative or only a positive reaction to light. The quality of the reaction can be influenced by the stage of development of eggs or larvae, age characteristics, feeding status, season, time, the physiological state of fish, morbidity, etc. A promising area of research is the study of the influence of light on the hormonal status of the body and reproduction of fish. Also, the light pollution and its influence on the physiology of anamnia vertebrates are important.

“…Moreover, the development of a sophisticated olfactory epithelium, very rich in microvillar and ciliated cells, supports the enhanced olfactory capability required during the benthonic phase (Appelbaum, Adron, George, Mackie & Pirie ). Neuromasts are sensory receptors that respond to mechanical stimuli and are probably involved, in low light conditions, in the capture of Artemia , which produce vibrations (Mukai & Lim ). Taste buds and the olfactory epithelium respond to chemical stimuli such as free amino acids released from live prey and MD (Mukai, Tuzan, Lim & Yahaya ), while barbels are mainly necessary in benthic species to recognize the sea bottom and search for prey items (Lombarte & Aguirre ).…”

Effects of light intensity on growth, feeding activity and development in common sole (Solea soleaL.)larvae in relation to sensory organ ontogeny

et al. 2014

The effects of four light intensities (1000 lx, 500 lx, 50 lx, 3 lx) on growth, survival and feeding activity in common sole (Solea solea L.) larvae were studied from 4 to 51 days post hatching (dph). During the pelagic larval stage (4–12 dph), larvae reared at 3 lx showed a lower growth. From 19 onwards, the larvae reared under 3 lx displayed a significant (P ≤ 0.05) higher SGR than the other treatments and a higher final weight compared to 1000 lx and 500 lx. Survival rate was higher under intermediate light intensities (500 and 50 lx). Larvae reared at 3 lx displayed a significant delay in the degree of metamorphosis compared to the other treatments, while at 33 dph metamorphosis was completed under all treatments. Histological examination revealed the importance of vision and light in the first feeding of this species, while after metamorphosis, the full development of other sensory organs indicated that feeding activity is also mediated by chemosensory perception. Results indicate that high light intensity seems to be more suitable during the pelagic larvae, while the opposite would ensure better growth from the onset of metamorphosis to the benthic phase.

“…There exists a threshold of illumination below which fish larvae are unable to detect food through ocular acuity, and might die after vitelline absorption and utilization irrespective of the impacts of other factors (Boeuf & Le Bail, ; Bromage et al., ; Mukai & Lim, ; Villamizar et al., ). This threshold, critical for larvae at the outset of exogenous feeding, allows larvae to develop a normal feeding incidence that relies on larval vision and colour discrimination.…”

Vitellus utilization under concurrent variations in temperature and light intensity in Ussuri catfish, Pseudobagrus ussuriensis

et al. 2018

The combined effects of temperature (18-34°C) and light intensity (100-1,800 lx) on the vitellus utilization, duration of vitelline absorption and larval growth in Pseudobagrus ussuriensis were studied under laboratory conditions using a central composite design and response surface methodology. The results showed that the firstand second-order effects of temperature and light intensity were significant (p < 0.05), the interactive effect between temperature and light intensity was nonsignificant (p > 0.05) and the effects of light intensity were greater than that of temperature. Predicated on the reliable models of vitelline utilization regarding temperature and light intensity, the optimal rearing environment shaped by a temperature/light intensity of 25-26°C/1,030 lx (12.98 μmol m −2 s −1 ) was obtained via model optimization. Verification results attained under laboratory conditions showed that vitelline utilization was most efficient at these optima. The application of the environmental optima would contribute to refining the seed quality in the larviculture of this species.
