      An annotated list of scientific and english common names of commercially important penaeid prawns and shrimps 

      H Motoh - 1977 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Technical report / SEAFDEC Aquaculture Department; No. 2
      There are 318 species of penaeid shrimps (Family Penaeidae) recorded in the world, of which about 80 species are placed under exploitation in fishing industry and/or cultivated artificially. The species under the genus Penaeus are particularly favored for human consumption because of their larger size and palatability and are therefore exposed to extensive capture by fishing boats. The shrimp fishing industry has developed in various parts of coastal waters worldwide extending from the temperate to tropical zones in both hemispheres. The nations engaged in shrimp fishing are numerous; Japan, U.S.A., Mexico, Thailand, India, lead in terms of volume of catch. Japan, for instance one of the large shrimp consuming nations in the world, has been dispatching shrimp fishing boats to many countries whether on her own capital or in joint ventures. Japan annually imports some 100,000 tons of frozen shrimp of which penaeids rank first in quantity. Meanwhile, the demand for shrimp is expected to rise in the years to come.

      The shrimp fishing industry and its operation are conducted and managed naturally, as indicated above, under international agreement. However, confusions arise particularly regarding the common names of shrimp caught or the products. It is evident that many commercial species of penaeids are given common names which differ from one country to another. For instance, the so-called "white shrimp" adopted by commercial circles includes nine different species. Understandably, these nine species, aside form being closely related biologically, are characterized by whitish coloration of the body.

      The present list was compiled to show the status of shrimp nomenclature, based on available literature, giving scientific names and English common names adopted or applied. The present article is written in the hope that the common names of penaeid shrimp shall be standardized internationally at least in English. Needless to say, the standardization will contribute greatly to world trading, as well as to scientific studies.

      Artificial fertilization of eggs and early development of the milkfish Chanos chanos (Forskal) 

      H Chaudhuri, JV Juario, JH Primavera, R Mateo, R Samson, ER Cruz, EO Jarabejo & JT Canto Jr. - In Induced spawning, artificial fertilization of eggs and larval rearing of the milkfish Chanos chanos (Forskal) in the Philippines, 1977 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Technical report / SEAFDEC Aquaculture Department; 4
      Hydrated eggs obtained from a female milkfish were artificially fertilized with the milt collected from a male injected with acetone-dried pituitaries of salmon. The fertilized eggs (1.1 to 1.25 mm in diameter) developed normally in seawater in basins and Petri dishes at a salinity of 30-34 ppt and successfully hatched in 25 to 28½ hours at a temperature of 26.4-29.9°C. The yolk was completely absorbed in about 2½ days and at this period many postlarvae died. A few larvae were reared up to 5 days but all died within 6 days. Effects of feeding the postlarvae from the third day with freshly hatched trochophore larvae of oysters obtained from eggs artificially fertilized in the laboratory could not be ascertained.

      Breeding and larval rearing of the milkfish Chanos chanos (Pisces: Chanidae) 

      WE Vanstone, LBJ Tiro, AC Villaluz, DC Ramsingh, S Kumagai, PJ Dulduco, MML Barnes & CE Dueñas - In Induced spawning, artificial fertilization of eggs and larval rearing of the milkfish Chanos chanos (Forskal) in the Philippines, 1977 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Technical report / SEAFDEC Aquaculture Department; 4
      Two sexually maturing female milkfish were captured in April 1977 and induced to spawn by means of acetone-dried Pacific salmon pituitary powder. The eggs were fertilized and incubated and the resultant young reared to 74-day old, 11 cm long fingerlings. Newly fertilized eggs averaged 1.16 mm in diameter and each had a narrow perivitelline space containing several cortical granules which disappeared within a few minutes. The yolk was slightly yellowish, devoid of oil globules and very finely granulated. Embryonic development was very similar to that of other pelagic fish eggs and hatching occurred between 35 to 36 hr at a salinity of 32 ppt and a temperature range of 28.4-29.2°C.

      Design, operation and economics of a small-scale hatchery for the larval rearing of sugpo, Penaeus monodon Fab. 

      RR Platon - 1978 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Aquaculture extension manual; No. 1
      One of the major problems in the mass production of sugpo is how to obtain a constant supply of fry. Since ultimately it is the private sector which should produce the sugpo fry to fill the needs of the industry, the Barangay Hatchery Project under the Prawn Program of the Aquaculture Department of SEAFDEC has scaled down the hatchery technology from large tanks to a level which can be adopted by the private sector, especially in the villages, with a minimum of financial and technical inputs. This guide to small-scale hatchery operations is expected to generate more enthusiasm among fish farmers interested in venturing into sugpo culture.

      Development and management of milkfish broodstock 

      OS Reyes, EGT de Jesus-Ayson, BE Eullaran, VL Corre Jr. & FG Ayson - 2015 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Aquaculture extension manual; No. 62
      The manual provides developed and refined techniques for collection and transport of spawned eggs and larvae, as well as larval rearing. It also describes the necessary facilities for maintaining milkfish broodstock.

      Guidelines on transporting broodstock, performing biopsy to determine sex of spawners, collecting and cleaning eggs, packing and transporting eggs to hatchery, incubating and hatching eggs, and packing and transporting of larvae are also provided in the manual.

      The importance of nutritional quality of the diet in relation to the performance of the milkfish broodstock and quality of resulting eggs and larvae is also explained in the manual.

      Broodstock feeds are enriched with vitamin C, beta-carotene, and other nutrients for better reproductive performance of broodstock and better egg and larval quality. It also offers formula to initially estimate the number of spawned eggs and determine the hatching rate.

      The manual guides stakeholders and operators who are interested in setting up breeding facilities for milkfish.

      Development of a brood stock of the jumbo tiger prawn, Penaeus monodon Fabricius 

      AC Santiago Jr., L Rodriguez, R Mateo & R Obregon - 1976 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Technical report / SEAFDEC Aquaculture Department; No. 1
      The full-scale cultivation of sugpo, P. monodon Fabricius, could only be realized if there is an assurance of continuous supply of fry. Obviously, a steady supply will depend largely on the availability of spawners. In December 1975, roughly after 2 1/2 years of intensive study, for the first time in the world, SEAFDEC Aquaculture Department has succeeded in inducing P. monodon to mature and produce normally the first generation of postlarval fry, thereby successfully effecting the completion of P. monodon's life cycle while in captivity. Another significant study the Department has initially carried out which could help augment and stabilize the supply of spawners and eventually stimulate the establishment of more prawn hatcheries and the development of ponds for prawn culture as a major export-oriented, dollar-earning industry, is the possible development of ovarian rematuration of spent spawners.
