Rastrelliger kanagurta
(73.7%) as compared to
Liza vaigiensis
(72.8%) and
Scomberoides tol
(70.7) (Table 2).

The highest carbohydrate content was found in
Liza vaigiensis
(22%) as compared to other species
Scomberoides
tol
(20.4%) and
Rastrelliger kanagurta
(13.3%) (Figure 2). Protein concentration was high in
Scomberoides tol
(52%) as compared to other species
Liza vaigiensis
(48%) and Rastrelliger
kanagurta
(40%) whereas ash was high
in Rastrelliger
kanagurta
(37.5%) and low in
Liza vaigiensis
(20%) and
Scomberoides tol
(21%) (Figure 2). The
mullet fish
Liza vaigiensis
has high concentration of moisture (6%) as compared to both mackerel fishes
Rastrelliger kanagurta
(4%) and
Scomberoides tol
(2%) (Figure 2).

Liza vaigiensis, Rastrelliger kanagurta
and
Scomberoides tol
collected from Sonmiani
Balochistan coast
Correlation of both total length and width with fresh weight was r
2
= 0.904 (Figure 3; Figure 4). Both total and
standard length and width have positive significant relationship with carbohydrate (r
2
= 0.642, r
2
= 0.807 and r
2
=
0.642 respectively) and moisture (r
2
= 0.866, r
2
= 0.721 and r
2
= 0.866 respectively) (Figure 5; Figure 6). It is also
observed that there was positive significant relationship was found in between biochemical constituents of
Scomberoides tol
and
Rastrelliger kanagurta
(r
2
= 0.935),
Scomberoides tol
and
Liza vaigiensis
(r
2
= 0.995) and
Rastrelliger kanagurta
and
Liza vaigiensis
(r
2
= 0.937) (Figures 7; Figure 8; Figure 9).
