    Get PDF
    Organisms generally increase in size (length, weight) during development. The key factors that influence the growth of fish are the quantity of food available, the number of fish utilizing same food source, temperature, oxygen and other water quality factors besides the size, age and sexual maturity of the fish. Every animal in its life exhibit growth both in length and in weight and the relationship between these two has both applied and basic importance. The length-weight relationship is one of the standard methods that yield authentic biological information and is of great importance in fishery assessments. It establishes the mathematical relationship between the two variables, length and weight, and helps in assessing the variations from the expected weight for the known length groups

    This paper presents the trend of marine fish landings of Orissa during the period 1975- 2006. The marine fish landings of Orissa indicated a general increasing trend from 16,804 t in 1975 to 1, 01,500 t during 2005 contributing to an average of 2.6% of the all India marine fish landings. Demersal fishery resources including crustaceans and molluscs dominated the landings ranging between 6575 t during 1977 to 56,556 t during 2005. The pelagic fishes contributed to 8497 t during 1977 to 44472 t during 2005. A total of six types of mechanized and motorized gear each and seven types of non-motorized gears were operated off Orissa during 2005 & 2006.The total effort both in units and Actual Fishing Hours (AFH) was greater during 2005 (5.91 Lakh units & 35 Lakh AFH ) than during 2006 (5.49 Lakh units & 31 Lakh AFH). While motorized gears expended more effort in terms of units, mechanized gears had put in more AFH during both the years. Gear wise, all the resources were landed more by mechanized gears followed by motorized gears and non-motorized gears. Resource wise, pelagic fishes were contributed mainly by carangids (21%), ribbon fishes (19.5%) and other clupeids (13.5%). The major contributors of demersal resources were croakers (35%), pomfrets (17%), catfishes (16%), and silver bellies (5.4%). Crustacean resources were dominated by penaeid prawns (78%) followed by non-penaeid prawns (11.6%) and crabs (9.25%). Seasonally, all major resources were landed more during October to December and January to March perio

    Karnataka, with a 300 km coastline supports livelihood of 1.7 lakh fisherfolk population residing in 144 marine fishing villages. The marine fish production in the state reached a record 5.29 lakh tonnes (t) in 2016. The increase is attributed to the hike in the landings of Priacanthus spp., lesser sardines and oil sardine in 2016 as compared to 2015. Among the three coastal districts of Karnataka, Dakshina Kannada and Udupi districts contributed 38% each, followed by the Uttara Kannada (24%). The Mangalore and Malpe Fisheries Harbours are the main contributors in the Dakshnina Kannada and Udupi districts respectively
