Seasonal distribution of some oceanographic Parameters off southwest coast of India Relevant to pelagic fisheries

The temperature, salinity and oxygen distributions associated with the thermocline of the shelf and adjacent waters off the southwest coast of India are presented seasonwise. The seasonal differences in the location of the thermocline and the magnitude of the vertical temperature gradient within the thermocline are also presented and discussed. The commercially important pelagic fisheries of the waters are also discussed in the light of environmental conditions

Transparency Meter to Study the Underwater Light Penetration in the Sea

An electronic device using a selenium photocell has been designed and fabricated to measure irradiance of light at various levels of the water column to relate irradiance with biological productivity. The instrument is portable and easy to operate at sea. Its performance at sea is found satisfactory
