Fishing is a worldwide pastime enjoyed by millions of people. Ocular fishing injuries though uncommon may cause potentially devastating ocular trauma. We report a rare case of penetrating injury of the cornea by a barbed fish hook and its successful surgical management by "cut-it out technique". We are discussing the various techniques available for removal of fish hooks. The hook can be successfully removed with minimal trauma to ocular structures by understanding the structure of the fish hook and by employing the appropriate method of extraction.

Aquatic ecosystems are highly dynamic environments vulnerable to natural and anthropogenic disturbances. High-economic-value fisheries are one of many ecosystem services affected by these disturbances, and it is critical to accurately characterize the genetic diversity and effective population sizes of valuable fish stocks through time. We used genome-wide data to reconstruct the demographic histories of economically important yellow perch () populations.

To investigate the infection of fish of the genus by (Monogenea) parasites in the karst region of Yunnan (Southwest China), individuals were obtained from the rare and vulnerable host black loach . Based on morphology and partial internal transcribed spacer (ITS) sequence data, we identified and described a new species n. sp.

In the Philippines, nemipterid fishes hold substantial economic importance due to their high market value. However, the local longline fisheries lack specific regulations for managing the capture of these fishes. This study aimed to determine the optimum hook size for increasing catchability in nemipterid fishing while minimizing bycatch, thus promoting sustainable fisheries.

Temperate fishes often spawn in response to environmental cues, such as temperature, thereby facilitating larval emergence concurrent with suitable biotic and abiotic conditions, such as plankton blooms. Climatic changes may alter the reproductive phenology of spring- and autumn-spawning freshwater fish populations. Such effects may depend on the sensitivity of reproductive phenology to ambient temperatures.

Nurse sharks (Ginglymostoma cirratum), especially juveniles, are often encountered by near-shore and shore-based recreational anglers and are suggested to exhibit minimal behavioral and physiological responses to capture, largely based on studies of adults using commercial or scientific fishing methods. To quantify the sub-lethal effects of recreational angling on juvenile nurse sharks, 27 individuals (across 31 angling events) were caught using hook-and-line fishing methods. Over a 30-min period, 4 blood samples were taken with variable time intervals between sampling (i.
