The most common injuries (by marine organisms) reported by fishermen were caused by stingrays (30%), weever fish (22%), rabbit fish (13%), and marine catfish P.lineatus (10% or 8 cases)”. Israeli trawl fishermen reported a rise in the prevalence of injuries and concern over their (P. lineatus) severe effects only from 2003–2004 and onwards. Most injuries from this economically worthless fish occurred when the fishermen removed them from the catch with unprotected hands. The intensity of pain inflicted by this fish was high, sometimes described as intolerable and causing the fishermen to seek medical attention. " "Gweta, S., Spanier, E., and Bentur, Y. (2008).

Juveniles totaled 3,201 and accounted for 86.9% of the specimens (in terms of abundance). {The main problem identified with these discard rates was an increase in the time required to sort the catch, as P.lineatus is highly venomous and extra care is needed for its handling.

Almost all of the fishers (97%) stated that this species damages the fish entangled in their nets. Therefore, it causes financial losses for the fishers by reducing fishing yield and value. The study revealed that 78% of ?sher’s ?shing gear {longlines and gillnets} was damaged by Lagocephalus sceleratus; The fishing gear loss per vessel in 2013-2014 is 2,554 Turkish Lira/year and labor loss for longline is 64.7 TL/year. The damage caused by pufferfish to the fish entangled in the fishing gear could not be monetized. The monetary loss in small-scale fishing doubled within two years (compared with the 2011-2012 study, see above). " "Ünal, V., and Göncüo?lu Bodur, H. (2017).

(Field surveys ascertained that) lionfish and spiny lobsters were often caught together in traps but there was a negative correlation between the catch rates of lionfish and that of legal size lobsters, which has led fishers to argue that lionfish negatively affect the catch of lobsters. (Based on manipulative lab experiments) negative correlation between catch rates of legal-size spiny lobsters and lionfish on spiny lobster traps are a likely result of the antagonistic relationship between these two species. Lobsters, however, are likely to exclude lionfish from traps rather than the other way around, therefore; the negative correlation does not reflect a negative impact of the presence of lionfish on the catch rate of lobsters " "Lazarre, D.

When asked how the presence of lionfish had affected their fishing, 48% stated that lionfish in and around their condos forced them to be more cautious (spending up to 1 additional minute per condo when harvesting lobsters).
