The correlation of dietary cholesterol with heart ailments has led people to become more health conscious and in this scenario the present study was carried out to investigate the monthly variations in Indian squid to aid in better decision making by consumers. Squid samples [Uroteuthis (Photololigo) duvaucelii] were collected in quadruplicate on monthly basis for the period of one year (2015-2016) and subjected to analysis for cholesterol, non-saponifiable matter (NSM) and proximate composition. The cholesterol content of squid was highest (279 mg%) and lowest (7.3 mg%) during the months of April and December with respect to total length and size, respectively. A monthly variation in proximate composition of squid with respect to the total length and size was observed. No correlation observed between fat content and cholesterol in squid. Significant difference in cholesterol content was observed monthly in the squid samples. NSM content (0.23%) was negligible and undetectable in the samples.

The material used for the fish trawl is HDPE (High density polyethylene) and the knot type used for construction is a single trawl knot. Blue colour multifilament netting twine was normally used, having twine diameter of 1.25 mm for construction of netting of wing and square section while 1.00 mm twine was used for the belly, lengthener and cod end section. The mesh size of the wing and square section was 600 mm and gradually reduced down to the cod end section (18 mm). The net was specifically used to catch Ribbonfish, Squid, Croaker, Pomfret etc.

Cast net without central line and without pockets were made up of 3 to 6 panels joined together vertically by take up ratios to form main conical webbing. PA monofilament having diameter of 0.5 to 1.3 mm was commonly used for construction of main webbing of cast net. Two rows of selvedge meshes of PA multifilament of 210 D×3×3 were provided at bottom edge of the net. Selvedge was absent at the apex end of the net. For all panels of main webbing and for selvedge section, mesh size varied from 20 to 40 mm. At apex, all meshes were closed together and were tied to the pulling chord which was made up of PP twisted multifilament rope of 3 to 4 mm diameter and 4 to 7 m in length. For first three panels, joining of the panels was carried out by 1:2 ratio by making knot locally called as Vasan. From panel number 4 to 6 the ratio was maintained as 2:3. The total depth of net varied from 3 to 5 m. PP twisted multifilament rope of 18 to 26 m in length having diameter of 3 to 5 cm was used as sinker line to which oval shaped lead sinkers having 3 to 4 mm diameter and 180 to 225 in numbers were tied at 12 to 16 cm interval. The fish species harvested by the cast net were mullet, lady fish, silver biddies, glass fish, shrimp and crabs.

Temporary barrier locally known as Van net was a very simple method employed to trap the fish and operated at a depth of 3 to 4 m. The gear comprised of a long wall of netting supported by head rope, foot rope and wooden sticks or bamboo poles at regular intervals and operated in the area of tidal influence. PE multifilament twine having specification ranging from 210D×6×3 to 210D×12×3 and mesh size varying from 20 to 35 mm was commonly used for construction of main webbing. Total hung length and hung depth ranged from 200 to 355 m and 2 to 3.8 m, respectively. Number of meshes in length and depth ranged from 6428 to 13000 and 70 to 190, respectively. PP twisted rope of 1.5 to 2.5 mm diameter was used as head rope on upper edge and foot rope on lower edge. A total 25 to 45 wooden poles of 3.5 to 4.5 m height and 40 to 60 mm diameter were used to stretch the long wall of webbing horizontally and vertically as floats and sinkers were not used.

The bobbing line locally known as Sarsara was operated at a depth ranging from 10 to 18 m to catch Scad fish (Kokeri). Its main line was made up of PA monofilament twine of length varying from 6 to 12 m and diameter ranging from 0.16 to 0.25 mm. Bob was made up of 15 to 30 cm PA monofilament of same specification as that of the line. Hand line consisting of a line and bait with hook was operated at a water depth of 4.5 to 12 m and was made up of PA monofilament twine having a twine diameter varying from 0.23 to 1 mm of length ranging from 5 to 16 m. Barbed 'J' shaped steel hooks of 7 to 13 number were normally used.
