Settlement preference of the brown mussel, Modiolus metcalfei, Hanley and its implication on the aquaculture potential of the species
(Fisheries Research Society of the Philippines, 1978)A study on the settlement preference of M. metcalfei was made in Banate Bay, Iloilo, using four types of materials as spat collectors. During the six-month study period, not a single Modiolus spat was found in any of the ... -
Preliminary studies on growth and survival of Penaeus japonicus postlarvae fed with Tapes philippinarum and commercial formula feed.
(Fisheries Research Society of the Philippines, 1978)The postlarvae were maintained in 5-l round plastic aquaria and provided with aeration for a 28-day feeding period. Highest survival rate of 100% was obtained when the postlarvae were fed with Diet-B. Growth, in terms of ... -
Mass production in concrete tanks of sugpo Penaeus monodon Fabricius spawners by eyestalk ablation
(Fisheries Research Society of the Philippines, 1978)Two batches of 196 and 181 P. monodon females were ablated on one eyestalk in March and July 1977, respectively, and a control batch of 180 unablated females was stocked in July 1977. The females were stocked with males ... -
Present prawn culture in the Philippines.
(Bureau of Fisheries and Aquatic Resources, 1978)This paper discusses present prawn culture practices in the Philippines, as well as the experiments which are conducted at the SEAFDEC Aquaculture Department by reviewing production of fry, production of juveniles in nursery ... -
A study on certain aspects on the biology and control of Caligus sp., an ectoparasite of the adult milkfish Chanos chanos (Forskal)

Use of hormones in breeding cultivated warm-water fishes with special reference to milkfish, Chanos chanos (Forskal)
(Fisheries Research Society of the Philippines, 1978)The role of hormones in the controlled reproduction of a few test fishes is well documented. However, information on the mechanisms of endocrine regulation of ovulation in cultivated warm-water fishes is very meagre. ... -
Decapsulation of Artemia cysts: A simple technique for the improvement of the use of brine shrimp in aquaculture
(Elsevier, 1977)Although it is a common practice in different disciplines of fundamental research on the brine shrimp, and despite the very interesting applications that it offers for the use of Artemia in aquaculture, the "decapsulation" ... -
