Fishing Boat
Basic sorting of fishes according to species of fish are done on boat itself. Inbuilt compartments ranging from 12-20 in number Each compartment has a capacity of 600 kg. They are filled with crushed ice which remains frozen state for approximately 15 days. Average fishing duration is of 10 days
Quality inspection i.e. thumb impression test, bulging of eye, skin colors etc are carried out. These fish is then loaded in crates in a 3 layer ice pattern where layer of ice and fishes are present in alternation Crates used to transport fish Crushed ice is used as cooling medium for fish that are transported at short distance (intra-state) and cooling units are installed if fish are to be transported at longer distance (interstate ). industry MT11: Refer to response sheet KW12: Refer to response sheet KW13: re-written KW14: Refer to response sheet RS 15: yes, only head and viscera separated
Pink Perch Deheading/ gutting Some amount of de-heading i s done at dockyard manually After which heads are covered with ice and sold to fish meal industry and de-headed fishes are sold to surimi

Bawa Fishmeal and Oil co. Mangalore based fishmeal and fish oil producing industry Production capacity of 550 MT fishmeal per day
During peak season 600 tonnes of raw material is unloaded daily Basic Visual Inspection and temperature test is done for acceptance of raw material Raw material is received from Maharashtra, Goa, Karnataka, Tamil Nadu and Kerala (a) Location for procurement of raw material (b) Raw material unloaded from trucks
After metal separation using magnetic separator raw material is loaded on screw conveyor moving towards cooker, where it is subjected to cooking operation. Steam heating is used for cooking, which prevents protein from excessive heat denaturation, characteristic of direct heating process. Temperature and time combination for cooking process depends on quantity of fish. Cooker
Cooked fish are then subjected to pressing in tin screw conveyor type press Pressing separates liquid fraction from solid fish pulp The twin screw press produces press cake with a moisture level ranging between 35-40% Screw Conveyor Press
Press cake obtained after screw press is subjected to drying in steam drier where a temperature of 85-90 C is maintained Moisture content in fishmeal is reduced to 6-9.5% from 40% in steam drier. Low moisture content ensures insufficient water level for support of growth of micro-organisms and halt any chemical degradation Drying process takes about 40 minutes Steam Drier
Sieving is done with sieve of 10 mesh size to obtain uniform size fishmeal particle and separate any impurity After sieving cooling is done using air cooler to reduce fishmeal temperature to 30-35 C Fishmeal is added with antioxidant (BHT, TBHQ) as per customer requirement. Fishmeal is pulverized in a hammer mill based pulverizer and milled into finer size particles (10 mesh size) Siever Pulveriser
A temperature increase of about 10 C is registered after pulverising. A water cooler is used to reduce the temperature of fishmeal to about 30 C From water cooler fishmeal is then transferred to silo Silo Water Cooler
Total time of production one batch is 60-90 minutes. Fishmeal is then packed into polypropylene bags of 50 kg unit size Shelf life is the final product (fishmeal) is about 1 year at room temperature. Depending upon protein content in the final product fishmeal is classified into four grades Grade Protein Content International market price (USD) Standard grade 60 1200 Prime grade 62 1250 Super prime grade 65 1350 Premium grade 68 1400
From press two fractions are obtained i.e. press cake and other is press liquor. For the fish oil press liquor after pressing step is collected in decanter from where stick water is sent to overhead tank for further separation of oil and water Stick water is pre-heated to a temperature of 80-85 C using plate heat exchanger Decanter Plate heat exchanger
After pre-heating stick water is subjected to centrifugation @ 7000 rpm which leads to separation of oil and protein water This fish oil is then inspected, collected, packed and sold.
