Comparison of nutritional status of field and laboratory reared Balanus amphitrite Darwin (Cirripedia: Thoracica) larvae and implication of starvation
(Elsevier, 2002)Experiments were carried out to evaluate the influence of rearing temperature and food concentration (20 and 30 degrees C, 1x10 sup(5) and 2x10 sup(5) cells ml sup(-1)) on the starvation threshold and nucleic acid content ... -
Decapod Larvae from the Nearshore Waters of Karwar
(Indian Association for Limnology and Oceanography, 1980)Abundance of decapod larvae at three stations in Binge Bay, Karwar has been reported based on surface collections taken during the period October 1975 to September 1976. The larvae were very common in the Bay and the ... -
Distribution of penaeid prawn larvae in the coastal waters of Goa
(CSIR-NISCAIR, 1986)Larval and postlarval distribution of 4 commercially important penaeid prawns was studied in the coastal waters of Goa extending up to 40 m depth zone during Jan. - Dec. 1981. Larval stages of Metapenaeus dobsoni and ... -
Epizoic and ectoparasitic protozoans from crab larvae
(Indian Association for Limnology and Oceanography, 1986)A suctorian, Ephelota gemmipara Hertwig, infesting the zoea of the peacrab, Porcellana and an ectoparasitic flagellate Ellobiopsis chattoni Caullery infecting the zoea of the crab were observed from off Cape Comorin, the ... -
Ichthyoplankton from Andaman and Nicobar seas
(Department of Ocean Development, New Delhi (India), 1996)Ichthyoplankton of the Andaman and NIcobar seas were studied for their spatial, seasonal and day and night variations from 357 zooplankton samples collected during 1986 to 1990. High density of fish larvae was encountered ... -
Key to the identification of larvae and postlarvae of the penaeid prawns (Decapoda: Penaeidea) of the Indian Ocean
(Indian Association for Limnology and Oceanography, 1982)Some of the major criteria for identifying the larvae and early postlarvae of the penaeid prawns of the Indian Ocean are presented based on the study on material collected during the International Indian Ocean Expedition ... -
Larvae of fouling organisms and macrofouling at New Mangalore Port, west coast of India
(NISCAIR, CSIR, 1995)Polychaetes, bryozoans, barnacles and ascidians were the dominant groups in the fouling community at New Mangalore Port. Polychaete and cirripede larvae were encountered throughout the year. Even though bivalve were present ... -
