The present study encompasses the traditional fishing method of Van net practiced in Ratnagiri, Maharashtra. 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.Keywords

Wular and Dal Lake are the two largest lakes of Kashmir contributing 70 per cent to the total fish landings of the state. The major catch from these lakes comprised of Cyprinus spp. which is exotic and Schizothorax spp. being the endemic to the lakes. During the study carried out on the operational and design aspects of scoop net and spears in Wular Lake and Dal Lake it was found that spear and scoop net were used in both the lakes. Two types of spears were used across Wular and Dal Lake i.e. multiple head spear, locally called as Panzri and double pronged spear, locally called as Narchoo. Scoop net, locally called as Khashiv and Kranz zal, was usually operated as a secondary gear.Keywords

The present study encompasses the traditional fishing method of cast net practiced in Ratnagiri, Maharashtra. 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.Keywords

It was observed that there is a trend in the Ratnagiri fishermen to cover the hull portion of their gillnetters by FRP, to extend its life. The overall length of such type of gillnetters ranged from 06.81 m to 10.00 m. Similarly, overall breadth and depth ranged between 1.25 to 3.10 m 0.47 to 1.6 m, respectively. Inboard engine of 7 to 24 hp were normally installed on the FRP coated wooden gillnetters having gross tonnage of 0.34 to 7.42 t. Construction cost of average size (8.5 m length, 2.2 m breadth and 1.0 m depth) wooden plank built boat coated with FRP, was approximately Rs. 4.0 to 5.0 lakhs, having a average life span of around 15 to 18 years, if maintained properly.Keywords

Trawling is one of the popular fishing methods along the west coast of India. However, there are regional variations in trawl net design, construction and operation. The present study deals with the general characteristics and specifications of fish trawl (137 m) operated along the Ratnagiri coast of Maharashtra. 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 netting twine material is normally used having twine diameter of 1.50 mm for construction of netting of wing and belly; while 1.0 mm twine is used for cod end. The mesh size of the cod end section was 18 mm while the upper and lower edge of cod end had 100 meshes in width and 150 meshes in depth.Keywords

In the fish processing industry generated waste during filleting of Talang queenfish (Scomberoides commersonnianus) was utilized for gelatin extraction in the present investigation. These waste materials being rich in collagen are valuable raw materials for gelatin extraction. The fish skin was used for gelatin extraction by ten different methods as described by different authors namely, Grossman and Bergman (1992), Gudmundsson and Hafsteinsson (1997), Gomez-Guillen and Montero (2001), Gimenez et al.(2005), Zhou and Regenstein (2005), Kolodziejska et al.(2008), Liu et al. (2008), Rahman et al. (2008), Benjakul et al.(2009) and Barve (2012). The results of yield were varied between 4.12 to 12.83% and gel strength was varied in between 162.51 to 226.11 g. Based on the yield and gel strength of extracted gelatins, the method of Barve (2012) was found the best method. This method revealed that yield and gel strength were 12.83% and 226.11 g, respectively and found significantly different comparatively other methods.Keywords
