The effects of manures and pelleted feeds on survival, growth and yield of Penaeus stylirostris and Penaeus vannamei in Panama
(Aquaculture Department, Southeast Asian Fisheries, Development Center, 1985)
Brackishwater ponds (0.8 m deep and 600 m2) on the Pacific Coast of Panama were stocked at 5/m2 with post-larval shrimp (1 cm, 0.05 g) collected from the wild. Species composition at stocking was 56% Penaeus vannamei, 33% ...
Genetic changes during development of penaeid shrimp
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
As penaeid shrimp grow from the earliest naupliar stages, through protozoeal and mysis stages, to postlarvae, they develop greater morphological and behavioral resemblance to the adults. Electrophoretic analysis of cytoplasmic ...
Studies on the artificial insemination and fertilization of grass shrimp, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The culture of grass shrimp, Penaeus monodon has become a fast-growing enterprise in Taiwan since formulated shrimp feed was successfully developed in 1978. In 1983, the total postlarval production for stocking reached 600 ...
Overview of penaeid culture in the Americas
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The paper discusses the reasons behind the farming success of Ecuador, as well as the limitations associated with farming throughout the rest of the Americas. Emphasis is given to specific farming practices, management ...
Osmotic, total protein and chloride regulation in Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The osmotic, total protein and chloride ion regulation in two size groups (10 and 30 g) of Penaeus monodon Fabricius was investigated. Preliminary experiments showed that osmolality, total protein and chloride concentrations ...
Nutritional value of marine yeast fed to larvae of Penaeus monodon in combination with algae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Saccharomyces cerevasiae and Rhodotorula aurantica, two marine yeast species, were fed to Penaeus monodon larvae (N6 to M1) singly and in combination with Tetraselmis sp. and Chaetoceros calcitrans in varying proportions. ...
Floating cage nursery culture system for Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The use of floating cages as nursery for Penaeus monodon postlarvae was tried at the Batan, Aklan Substation of the SEAFDEC Aquaculture Department. The cages were made of bamboo and measured 2 × 5 × 1.5 m (effective volume ...
Role of bacteria and meiofauna in the productivity of prawn aquaculture ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Detrital food chains, based on the use of manures and compost have been used in aquaculture for centuries. Heterotrophic bacteria convert organic detritus into protein and thus constitute an important food source in ponds. ...
The use of microencapsulated feeds to replace live food organisms in shrimp hatcheries
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
An adequate supply of hatchery produced shrimp fry is the major constraint to the intensification and growth of shrimp culture practices. If even 20% of the more than 500,000 ha of the world's existing tropical and ...
A review of the diseases of cultured penaeid shrimps and prawns with emphasis on recent discoveries and developments
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The development of the commercial culture of penaeid shrimps and prawns has been accompanied by the occurrence of diseases of infectious and noninfectious etiologies. Many of the important penaeid diseases are caused by ...
