Three baleen whales washed ashore along Uttara Kannada coast of Karnataka
Three instances of stranding baleen whales were
observed along the coast of Uttara Kannada district
of Karnataka during July and August 2016. All
strandings were recorded from the southern part
of the district.The first whale was washed ashore
on 20th July 2016 at Ramangindi, Dhareshwar, 12
km south of Kumta (140 21’ 710"N and 740 24’
360E). The whale was in a decomposed condition
when washed ashore. The post mortem was carried
out by a veterinary doctor. It was identified as
Bryde’s whale Balaenoptera edeni. The total length
of the male whale was 44 feet weighing
approximately 10 tonnes (Fig. 1). The second whale
washed ashore on 27.7.2016 at Hollangadde 7 km
from Kumta (140 27’ 432" N and 740 22’ 615" E was
also in decayed condition. It was identified as
baleen whale and measured 46 fee
Spectrum of the three dimensional fuzzy well
We develop the formalism of quantum mechanics on three dimensional fuzzy
space and solve the Schr\"odinger equation for a free particle, finite and
infinite fuzzy wells. We show that all results reduce to the appropriate
commutative limits. A high energy cut-off is found for the free particle
spectrum, which also results in the modification of the high energy dispersion
relation. An ultra-violet/infra-red duality is manifest in the free particle
spectrum. The finite well also has an upper bound on the possible energy
eigenvalues. The phase shifts due to scattering around the finite fuzzy
potential well have been calculated
Unusual landings of large sized Yellowfin tuna by purse seiners at Karwar, Karnataka
Unusual landings of large sized Yellowfin tuna
Thunnus albacares (Bonnaterre, 1788) was observed
at Baithkol Fisheries Harbour, Karwar during the
period 16th to 22nd February 2020. Six tunas were
landed by two purse-seiners with individual weights
ranging from 68 kg to 103 kg. One purse-seine unit
landed with only one yellowfin tuna weighing 68
kg in the early morning hours of 16.2.2020. The
other multiday purse-seine unit of OAL 19.8 meter
overall length (OAL) fitted with a 350 hp Sonatrac
engine was operated at a depth of 54 meter off
Belekeri (N 140 38’ 100” E 0730 52’ 500”) during
night hours on 18.2.2020 and four yellowfin tuna
weighing 103, 97, 82 and 78 kg each were hauled
in and sent immediately by a carrier boat to landing
