Kachal, a tackle for file-fish (family Balistidae : Pisces)
To suit local exigencies and condition several indigenous types of gear have been developed by fishermen from ancient times which though primitive and crude in appearance are efficient in their own way. One such gear is the Kaehal, used to capture the file-fish (Balistidae) along the south-west coast of India between Muttum and Vizhingam. Since good results are obtained at little cost, the gear is
used extensively by fishermen
Pumiliopsis spathepedes sp. nov., a cyclopoid copepod Parasitic on the eye of Sardinella sirm
The female of a new sipecies of copepod parasit;, Pumiliapsis spathepedes
is described from the eye of the sardine, Sardinella sirm from Tut'corin, South East
Coast of India. It was been compared with the only other known species in this
genus namely P. sardinellae. The species can easily be distingu'shed from all the
other bomolochids hitherto known by the enormously developed fifth leg
Global vs local cosmic strings from pseudo-anomalous U(1)
We study the structure of cosmic strings produced at the breaking of an
anomalous U(1) gauge symmetry present in many superstring compactification
models. We show that their coupling with the axion necessary in order to cancel
the anomalies does not prevent them from being local, even though their energy
per unit length is found to diverge logarithmically. We discuss the formation
of such strings and the phenomenological constraints that apply to their
parameters.Comment: 6 pages, uses RevTeX, no figur
The Consequences of Urban Air Pollution for Child Health: What Does Self-reporting Data in the Jakarta Metropolitan Area Reveal?
Since the early 1990s, the air pollution level in the Jakarta Metropolitan Area hasarguably been one of the highest in developing countries. This article utilizes selfreporting data on illnesses available in the 2004 National Socio-Economic HouseholdSurvey to test the hypothesis that air pollution impacts human health, particularlyamong children. Test results confirm that air pollution, represented by the PM10 levelin a sub-district, significantly correlates with the level of human health problems,represented by the number of restricted activity days (RAD) in the previous month.Results show that the younger the person, the higher the number of RAD in theprevious month; that is the impact of a given level of PM10 concentration is morehazardous for children
Impact of motorization on the traditional fishery at Tuticorin
Analysis on the impact of motorization on traditional fishermen
and deals with the total fish catch of various
gears using motorized crafts as compared with
total catch by non-motorized crafts using similar
gears and covers the period from 1986 to 1992. One reason for decrease in fish catch after
motorization of traditional crafts is the intensive
fishing carried out by motorized units in the
inshore areas traditionally fished by non-motorized
fishing units. It is also possible that
rsufficient recruitment is not taking place in the
fishing grounds to give an encouraging trend in
the motorized fishery
Heavy landing of brown pomfret at Tuticorin
From December 1992 to February 1993
bumper catch of brown pomfret Stromateus niger
was recorded at Harbour Point landing centre
which is a traditional site for shore seine operations
at Tuticorin. Some enterprising shore seine
fishermen after seeing schools of brown pomfret
moving near the Tuticorin harbour anchorage
used their encircling net to catch the
Peroderma tasselum sp. Nov. (Lernaeoceriformes; Copepoda) parasitic on the fish Stolephorus commersonii Lacepede
The female of a copepod parasite, Peroderma tasselum sp. nov. parasitic
on the fish Stolephorus commersonil is described from Tuticorin, southeast coast of
India. The species can be distinguished from the only other known species of
the genus, P. cylindricum, by the characteristic shape of the trunk
