Gill-damage in netted Tilapia mossambica Peters
Tilapia mossambica taken with gill-nets are often found with their gills damaged. Gill-filaments may be partly or completely lost; sometimes even the gill-arches are all missing (Plate IA). The operculum is usually undamaged but may have its posteroventral border slightly frayed (Plate IB). For comparison normal fish are shown in Plates IC and ID. Incidence of gill-damage increases rapidly with length of time the nets remain in the water; in the Parakrama Samudra a mere 2-3 hour interval between setting and lifting results in 5 to 20% of the fish being damaged.
