Abstract
The population survey was conducted to evaluate the population of common mallard
(Anas platyrhynchos) at ten wetlands of the Punjab. The mean population of ten year at
Chashma Barrage (65651464), Taunsa Barrage (1913191), Ucchali Lake (885232), Head
Qadirabad (24972), Head Marala (41852), Head Rasool (350), Khabbeki lake (9242), Head
Sulaimanki (1515166), Jhalar Lake (10321), and Head Islam (21739) was calculated and
recorded. The population of Chashma barrage was statistically highly significant (P<0.01) as
compared to other wetlands. Toevaluate the food preference, among total 40 gut samples, total
weight of gut was (102.583.451g), total weight of gizzard (39.92 1.279 g ), weight of food
material (4.340.170), gizzard weight without food material (35.33 1.208), weight of seed (1.62
0.092), weight of vegetation (1.960.087), weight of other material was (0.940.069). The
comparison between male and female showed that the total weight of gut, total weight of
gizzard, weight of food material, gizzard weight without food material and weight of seed was
statistically highly significant (P<0.01), weight of other material was statistically significant
(P<0.05) and weight of vegetation was statistically non-significant (P >0.05). The total 11 species
of plants were identified from the gut analysis which were, Ipomoea aquatic, Hydrilla
verticillata, Trapa natans, Oryza sativa, Vallisneria spirallis, Schenoplectus litoralis, Nymphaea
nouchali, Typha angustifolia, Potamogeton nodosus, Eichhornia crassipes and Cyperus
alopecuroides. The total 14 samples were found infected with different gastro- intestinal
parasites. The six species of parasites found were Amidostomum anseris, Hystrielus tricolor,
Notocotylus attenuatu, Hymenolepis gracilis, Diacranterian introversa, and Diorchis stefanskii.
Four species were recorded at Chashma Barrage, Taunsa Barrage and Head Sulaimanki. Three
species were recorded at water-logged area of Bahawalnagar and Faisalabad and two species
were recorded at Head Marala. Hymenolepis gracilis, Dicranotaenia introversa and Diorchis
stefanskii was recorded from the four wetlands.Hystrielus tricolor and Notocotylus attenuates
was recorded from the three wetlands and Amidostomum anseris was recorded from the two
wetlands. The current study has provided the valuable baseline information for the
management planning, conservation, improvement of habitat, host-parasite interactions,
fitness, and health status of this species.
