“…Nonetheless, the spectral characteristics of visual pigments, inferred from a study of retinal extracts, are known only for rods in this species (Hasegawa & Miyaguchi, 1997). Here the author uses the information from GenBank and the known relationships between aa sequences of opsin genes and absorption maxima of visual pigments that have been confirmed for many fish species and are widely used (Carleton et al ., 2020; Mitchell et al ., 2021; Miyazaki et al ., 2018; Yokoyama, 2000).…”

The main goal of this study was to clarify whether the spectral properties of retinal photoreceptors reflect the features of behaviour of closely related fish species cohabiting shallow marine and fresh waters. The spectral sensitivity of photoreceptors was compared between two smelt species, Hypomesus japonicus and Japanese smelt Hypomesus nipponensis. The spectral absorption of the visual pigments was measured using microspectrophotometry. In H. japonicus, a mostly marine species, all photoreceptors contained visual pigments based on retinal and were distributed differently in specific retinal areas. The absorbance maxima (λ max ) of rods and long-wavesensitive members of double cones throughout the retina amounted to 507 and 573 nm, respectively, but the λ max value of the short-wave-sensitive members of double cones and single cones in the temporal hemiretina showed a significant blue shift compared to the nasal hemiretina: 485 vs. 516 nm and 375 vs. 412 nm, respectively, thus enhancing the short-wave sensitivity of the temporal hemiretina. In H. nipponensis, an euryhaline species, the estimated λ max value of both rods and cones significantly varied between the groups caught in different localities (sea, river or estuary) because of the presence of rhodopsin/porphyropsin mixtures. The longwavelength shift in rod and cone photoreceptors was observed because of changes in the chromophore complement in closely related but ecologically different species dwelling in freshened bodies of water. Considering the data available in the literature, several putative common opsin genes have been suggested for species under study.

“…The significance of the mean was 0.04<0.05, indicating that there is a significant difference in the mean of catches between the two operating methods. The visual nerves of coleoidea are sensitive to blue-green light [ 33 ]. In the first experiment, an appropriate cyan light increase into white light can significantly increase the catch of coleoidea, which is similar to the results of many other fish species [ 34 , 35 ].…”

Falling nets are a type of fishing gear that appeared and developed rapidly in the northern of South China Sea in the early 1990s. We have developed Light-emitting diode (LED) fishing lamps to replace metal halide (MH) lamps that reduce fuel consumption without reducing the catches. We conducted marine light-fishing experiments in the northern South China Sea during September 20 to 26, 2019 and August 29 to 31, 2021. The results in the first fishing experiment show that there is no significant change in catch of the falling-net fishing vessel when the white LED lamps (with a total power of 36 kW) were used instead of MH lamps (with a total power of 120 kW). Coleoidea catches of the falling-net fishing vessel increased significantly when white LED lamps (with a total power of 36 kW) and cyan LED lamps (with a total power of 6.0 kW) were used. The results in the second fishing experiment show that the total weight of catches of the cyan LED fishing lamps is more than that of the white LED fishing lamps, and the cyan LED light can attract Penaeus merguiensis, Thryssa dussumieri and Sardinella zunasi more effectively than the white LED light.
