Some morphometric traits of Liza aurata (Risso, 1810) in Umm Hufayn brackish lagoon, eastern Libya Mediterranean Sea coast (Published)
Eighty Liza aurata fish were collected from the artisanal catch of Umm Hufayn lagoon, eastern Libya, during January/ February 2018 for use in the present study. Values of key morphological parameters (descriptive, morphometric, and meristic) of the fish were established, correlated with each other, and related to fish length (as an indicator of growth and age) by power and linear regressions. The mean length of the fish was 21.331cm corresponding to weight of 89.011g. The established meristic form was: D1, IV; D2, I+ 6-9 (8); A, III, 7-12 (9); P, 12-18 (15); V, I + 4-7 (5); LL, 34-54 (42), numbers between parentheses are modes of counts. Power and linear length-weight relationship were Y=0.006X3.111, R2=0.891and Y=15.89X-250.1, R2=0.824, fish growth is almost isometric; Fulton and Clark condition factors were 0.8498± 0.01486 and 0.6651± 0.01145. These factors did not correlate significantly with fish length, i.e. they did not change significantly during fish growth.
