study in Suruga Bay recorded females with large yolked ova inside the ovary year-round, but females in the western part of the bay were only found to carry egg cases from October to January, suggesting that the interval between egg depositions is shorter at that time. Males and females attain sexual maturity at approximately and long respectively. However, there is a Taiwanese record of an immature male long. Human interactions Uncertain numbers of gecko catsharks are caught incidentally by commercial trawl fisheries. In Taiwan, it is occasionally brought to market and processed into fishmeal for aquacultural use. This species' small size and oviparous mode of reproduction may make it more resilient to fishing pressure than other sharks. As the gecko catshark remains common off Japan and may be protected from fishing in the deeper parts of its range, the International Union for Conservation of Nature (IUCN) has assessed it as of Least Concern.
