“…The DO levels of North 24 Parganas district farms (12.74±2.27 ppm) were significantly higher (P<0.01), possibly due to the provision of aeration facilities. The results of the water quality parameters corroborate the findings of Priyadarsani & Abraham (2016) recorded in a low saline shrimp pond of West Bengal. The ammonia-N levels varied in different farms with a maximum of 1.54 ppm.…”

Penaeus vannamei farming has been the major aquaculture practice in the Indian Sundarbans. This study investigated the physicochemical characteristics, management practices, distribution of vibrios, and the prevalence of bacterial, parasitic and viral diseases in 14 P. vannamei intensive culture farms in the Indian Sunderbans during 2016. The total heterotrophic counts of the pond water ranged from 3.53 to 6.21 log 10 cfu/ml. The presumptive vibrios were in the range of 2.40-4.99 log 10 cfu/ml. Mild vibriosis was noted in 3 farms. Twenty out of 21 isolates from the haemolymph samples were confirmed to be Vibrio parahaemolyticus by the PCR amplification of the toxR gene. No acute hepatopancreatic necrosis disease (AHPND) causing V. parahaemolyticus (Vp AHPND ) strain was, however, detected. Of the 14 shrimp farms surveyed, only one farm sample was white spot virus (WSV) positive and all others were negative. All the P. vannamei farms were negative for infectious hypodermal and haematopoietic necrosis virus, hepatopancreatic parvo-like virus, and infectious myonecrosis virus. No incidence of Enterocytozoon hepatopenaei, white faecal syndrome, running mortality syndrome, protozoan infestation, and luminous vibriosis was observed during the survey period. The survival rate was 90-95% in the normal ponds, while the lowest survival was 60% in an asymptomatic WSV infected farm. The physicochemical characteristics of the farms were well within the optimum, except for the WSV infected farm, which had high ammonia levels. Due to the lack of awareness on the P. vannamei farming practices and high operational costs, the biosecurity measures were not strictly followed in the surveyed farms.

“…The DO in an extensive pond was significantly lower (p<0.05) during flooding (5.37 mg/L) compared to draining (6.12 mg/L, Table 2). This supports Priyadarsani and Abraham's (2016) claim that oxygen dynamics depend on autotrophic and heterotrophic organisms' balanced production inside the pond system since extensive ponds contained both organisms. Nevertheless, DO in both flooding and draining were acceptable as it is above the minimum level (DENR AO 2016;Boyd 2003).…”

Fishponds around Manila Bay contributed an average of 41.19% of the total aquaculture production in the country. However, massive productions entail the intensification of ponds, which resulted in water quality deterioration. In 2016, Opinion et al. reported water quality in the aquaculture farms around the bay but does not include the other significant parameters required to be monitored, as stated in the DENR AO (2016). Thus, this study investigated the status of water quality in different pond systems surrounding Manila Bay. Extensive, semi-intensive, and intensive fishponds from adjoining provinces of Cavite, Pampanga, Bataan, and Bulacan were monitored throughout the rearing period. Results showed that levels of NH3-N (0.90 mg/L – 2.35 mg/L) and PO4-3 (1.02 mg/L – 2.42 mg/L) were not suitable for the culture of fish. Nevertheless, NO3-N, NO2-N BOD, TSS, DO, pH, and temperature were within the safe levels. Furthermore, results suggested that there should be a regular monitoring of water quality to regulate and manage fishponds surrounding the bay. Finally, strict compliance of the Code of Good Aquaculture Practices (GAqP) must be imposed to achieve water quality standards.
