- ItemRelative Condition Factor in Nandus nandus (Hamilton)(Society of Fisheries Technologists (India) Cochin, 1991)The relative condition factor (Kn) was calculated for males and females of Nandus nandus (Hamilton). In males the relative condition factor is above 0.7 in all months and showed two peaks, in August and in October whereas in females it is more or less steady with three median peaks - May, July and September. The results show that there is positive correlation between relative condition factor and reproductive cycle of this fish.
- ItemProcessing of Oyster Meat for Freezing(Society of Fisheries Technologists (India) Cochin, 1991)Experiments were conducted to determine the idealdepuration time for oysters and processing for shucking. A depuration time of 24 h reduced substantially the sand content. Steaming of oysters for shucking yielded better quality meat with good appearance than the hot water dipping method.
- ItemMethods for Comparison of Potentialities of Fishing Grounds and Efficiencies of Gears(Society of Fisheries Technologists (India)Cochin, 1991)The potentialities of fishing grounds were studied using the non-parametric methods; Wilcoxon test, Sign test, Run test and Median test and the two fishing grounds tested were found equipotential. Gear efficiency was also studied by non-parametric methods.
- ItemEffect of Ascorbic Acid Dip Treatment on Frozen Storage of Squid (Loligo duzzaucelii, Orbigny)(Society of Fisheries Technologists (India) Cochin, 1991)Squid (Loligo duvaucelii) was treated with 0.5% ascorbic acid solution for 10 min and both treated and control samples were frozen at -40°C and stored at -20°C The quality changts during frozen storage and shelf life were evaluated by following the physical, chemical, bacteriological and sensory characteristics. Ascorbic acid treatment was found to improve the quality and shelf life compared to control.
- ItemDrying of Anchovies (Stolephorus indicus) in a Solar Polythene Tent(Society of Fisheries Technologists (India) Cochin, 1991)The drying parameters of anchovies dried in solar tent dryer and under sun are compared. Though the temperature inside the tent was 14-15°C higher than the ambient temperature during early aftemoonin sunny days the drying rate did not show any significant difference between the two methods. Hence solar tent dryer offered little merit but for the protection given by tent against dust, insects, birds or sudden shower.
