Innofloc: Innovative biofloc technology for the nursery production of shrimp, Litopenaeus vannamei in tanks
(University of the Philippines Visayas, 2022)
Nursery systems are valuable production tools in shrimp aquaculture and are effective biosecurity facilities for the high-density culture of shrimp postlarvae (PL), resulting in healthy and uniform-sized juveniles. The ...

Evaluation of maturation promoting factor in polychaete (Marphysa sp.) on Indian white prawn, Penaeus indicus female broodstock
(Wiley, 2022-07-15)
Polychaete is considered the best maturation diet for penaeids; however, fluctuating supply and quality warrant detailed studies to understand the specific maturation-promoting factors present in polychaete. Indian white ...
Cage culture of tropical eels, Anguilla bicolor pacifica and A. marmorata juveniles: Comparison of growth, feed utilization, biochemical composition and blood chemistry
(Wiley, 2022-11-02)
This study examined the performance and suitability of two tropical anguillid eels, <i>Anguilla bicolor pacifica</i> and <i>A. marmorata</i>, under cage culture conditions. Juvenile eels (1.73 ± 0.14 g body weight) of each ...
An innovative biofloc technology for the nursery production of Pacific whiteleg shrimp, Penaeus vannamei in tanks
(International Network for Natural Sciences, 2022-10-09)
Nursery production of shrimp is usually done in small ponds; however, the use of small and circular tanks with plastic liners is gaining popularity. From an industry standpoint, there is still a need to assess how nursery systems can be of benefit to the shrimp production cycle. Hence, the use of small circular tanks coupled with the incorporation of biofloc technology was assessed in terms of its viability during the nursery production of the Pacific whiteleg shrimp, Penaeus vannamei. A 450m<sup>2</sup> plastic lined circular tank was installed and prepared for the stocking of P. vannamei postlarvae (PLs) at a density of 500 PLs per m<sup>2</sup>. Biofloc was produced and maintained throughout the nursery phase using brown sugar as carbon source at a carbon to nitrogen (C:N) ratio of 10. Water quality was monitored daily, while presumptive Vibrios were enumerated weekly. Sampling for growth was done at the 14<sup>th</sup> day post-stocking and weekly until harvest on the 30th day. The different water quality parameters were within optimum levels required for shrimp growth. Presumptive Vibrios were dominated by the yellow colonies. At the end of the nursery phase, there was 100% survival and the shrimp attained an average body weight of 1.26 g and a feed conversion ratio (FCR) of 0.43. Our results indicate that the use of small circular tanks with biofloc during the nursery production phase of whiteleg shrimp is feasible and can be incorporated in the grow-out culture of this shrimp species....
Molluscan aquaculture in the Philippines: A review
(Springer, 2023-04-25)
Molluscs are among the most valuable resources of the Philippines, an archipelagic country of 7,107 islands bounded by 36,000 km of coastline and 26.6 million ha of coastal waters. In 2020, production from mussels and ...
Grow-out culture of oyster Magallana bilineata (Röding, 1798) using pouches: A comparison of growth and survival in the river and earthen pond
(College of Agriculture and Food Science, University of the Philippines Los Baños, 2023-03)
Oysters are among the most in-demand aquaculture commodities in the Philippines and worldwide. With the decreasing culture area and the deteriorating water quality of oyster beds, there is a need to explore new culture ...
