Abstract

Embryonic development of Asian seabass, Lates calcarifer is a critical phase in the success of larval rearing production in a hatchery. Low production of larvae has been the drawback of the Asian seabass aquaculture owing to diseases and microbial infection to the eggs, causing low egg viability. This study aims to evaluate the effect of different doses of papaya leaf extracts during embryonic development to improve egg hatchability and larval survival. Six different doses of papaya leaf extracts of 2, 4, 6, 10, 20, and 25 mL were used as treatments arranged triplicates in five liter aquaria. The newly fertilized eggs (99 eggs) were immersed in each treatment for five minutes and fifteen seconds. Subsequently, the eggs were moved into 10 L incubation tanks, and samples were collected for embryogenesis observation. The hatchability of eggs was significantly different among treatments. The hatchability of larvae in group with dose of 4 mL was the best treatment (93.94 ± 0.1%) followed by 2 mL (93.88 ± 3%), and 6 mL (90.91 ± 3.0%). The different doses of papaya leaf extract significantly affected larval survival. The highest survival rate of larvae was 2 mL (93%) followed by 4 mL (90%) and 6 mL (70%). There was no significant difference in the hatching time of larvae. The fastest hatching time occurred at the dose of 6 mL about 13 hours and 30 minutes, followed by 2 mL and 4 mL treatment for about 14 hours. This study recommends that the doses of 2 mL or 4 mL of papaya leaf extracts have potential impacts on the improvement of larval rearing production for Asian seabass hatchery.

Abstract

This paper discusses the current status of tilapia aquaculture production, historical development based on the production growth, technological advances in genetic improvement and culture system, trade and product development, strategies, and policies in maintaining and improving national production. All data and information used in this manuscript were collected from available publications relating to the past and present status of tilapia cultivation in the country. Nowadays, Indonesia is the second-largest tilapia producer in the world with the contribution of about 25.89% to tilapia global production. In Indonesia, tilapia is the largest production among other cultured species. The annual growth production of tilapia is inccread 11.61% from 2011 to 2018. West Java Provinceis the largest tilapia producer followed by West Sumatra, South Sumatra, and Central Java. In the last six years, most of tilapia production comes from pond culture followed by floating cages, net cages, paddy fields, and pen culture. The success of tilapia culture is much influenced by technological improve in grow-out and genetic improvement of the local varieties. A side of that, trading and global market oriented are also established with various acceptable products. Tilapia aquaculture in Indonesia shows the succsess story of freshwater aquaculture program from nothing before 1990 to be something at present time. To maintain and increase the future production of tilapia, it needs strategies and policies in production and trade. The tilapia program maybe used as a role model for another economic imprortant freshwater species in Indonesia.
