This document discusses the Indian oil sardine fishery. It provides details on the distribution, peculiar characteristics, feeding habits, habitat, reproduction, fecundity, spawning season, age and growth, size of capture, mode of harvest, utilization, maximum sustainable yield, IUCN status, current stock status, management measures, and production trends of the Indian oil sardine. Key points include that it is distributed along India's western coast from Gujarat to Kerala, feeds mostly on plankton, reaches sexual maturity at 1 year old and 150mm in length, and production peaked at over 720,000 tonnes in 2012. Mesh size regulation is used for management.

4. Total Contribution In India 2015-2016 (%)

5. Peculiar character :-
• Caudal well forked, lobes pointed.
• Two larger scales at the base of caudal fin.
• Body fusiform, elongate & subcylindrical.
• Belly rounded, with low keel of scutes.
• No lateral line.

6. Food & Feeding habits :-
• Juvenile oil sardines – carnivorous(zooplankton).
• Feeding – planktonic crustaceans like
(copepods).
• Adult – phytoplankton feeders
• Omnivorous, feeding mostly on diatoms
• Structural adaptation in the gill rackers.
• Indicator species - Fragelaria oceanica (diatom).

7.  Habitat :-
 Pelagic.
 Shoaling, shoals of same age group.
 Reproduction :-
• Few instances of hermaphroditism have been
recorded (Antony raja, 1963).
• Sexes are separate.
• sexual maturity 140mm in length.

8.  Fecundity:-
• Prolific breeder and estimated to liberate about
70,000-80,000 eggs on an average.
• Vary depending upon the age, size, & condition of
fish.

9. Spawning season:-
• West coast peak spawning occurs during
Jun-Aug.
• East coast it is during Dec-Feb, Apr-Jun & Aug
–Oct
• Spawns only once in its life time.
• Breeding season rather than short

10. Age & Growth:-
• Grows to length of 155- 170mm in one year and 190 mm in
two years.
• Sexual maturity age of 1year length of 150 mm.
• The life span was presumed to be 2.5 years.
Size of capture:-
100 to 200 mm.

11. Mode of harvest:-
Gears:-
• Kerala three types -boat seines, Codam Vala,
Nonavala.
• Gujarat - Gill net, Cast net.
• Karnataka only - shore seine & cast net.
• Karnataka bigger shore seine - Rampani, yendi.

12. Crafts:
• Kerala –Dugout Conoe
• Bigger (odom)= 9-12 m long .
• Smaller(vanchi)= 8-9m long.
• Karnataka – outrigger(pandi).

13. Utilization:-
• Food both fresh & cured condition used in oil.
• Used Jute & steel industries.
• Used manure in coffee, tea, coconut, sugarcane & tobacco
plantations .
• Medicinal value.( fish oil capsules.)

14. MSY: - 0.21 million tonnes.
IUCN:-
Least concern ver.3.2
Status of stock:-
Nineties was 0.13 million tonnes.

15. Management measure:-
 Oil sardine: Sardinella longiceps
contributed 16841 t, accounting 6.4% of
the total fish landings and 16.6% of the
total pelagic catch. Purseseine was the
major gear (91%) followed by trawlnet
(5.2%) and gillnet (2.2%).
 Mesh size regulation.

17. Production trends:-
• Exceptionally good during -1923-24 = 57,000tn.
• Improved 1964-68 = 3.01 lakh tonnes.
• 1994 - Lowest production in -47,000 tonnes.
• 2012 – Highest production in 7,20,270 tonnes.
• Current production (2015-16) – 2, 65,667
tonnes.
