“…Similarly, most extensive ponds operate larger ponds than those of intensive or semi-intensive ponds [4]. The lower stocking density can obtain higher maximum production and survival rate as proven in other studies [50] . High survival rate can also be attainable in small intensive ponds with best management practices [51].…”

The shrimp industry in the Philippines play a vital role in the local and national economy through exports with markets abroad such as in South Korea, Japan, the USA, and others. This study aimed to describe the various cultural and operational characteristics of small-holder and commercial shrimp farms (P. vannamei) in the Davao region. It also evaluated the current risks and challenges faced by the shrimp farmers. A semi-structured questionnaire that focused on shrimp farmers, and operators in the region was used to collect data with N=41 farmers and operator. The results showed that respondents were engaged in small-holder farming activities which had an average yield of 10 tons/ha. On the other hand, the commercial farms that operate intensively had an average yield of 24 tons/ha. Most small-holder operators used electric generator machines to conduct aeration in their farms using paddlewheels and blowers. For the commercial farms, more paddlewheels and blowers were employed per pond compared to small-holder farms. Generally, the income of a farm was related to the yield of farms or the number of fries rather than social factors or size of farms cultivated. In terms of input costs, feeds were found to have the highest input costs, followed by the fry, fuel, labor, and others (fertilizers and water treatment chemicals). Most of the farmers mentioned that they are affected by diseases such as white spot syndrome (60%), black gills (35%), and red tail (5%). They perceived that the main contamination come from the water source (31%). The main threats mentioned are declining shrimp prices in the market, source of fry, water disposal, and overstocking, and water quality. Based on this study, farmers should follow good shrimp aquaculture practices and there is a need for them to regularly monitor their water quality.

The main threats mentioned were declining shrimp prices in the market, source of fry, water disposal, overstocking, and water quality. This study shows that small-holding fish farmers should be supported by the government so that they can make use of the more advanced technology employed by commercial shrimp farmers in order to increase their economic productivity and lower their environmental footprint.

“…The lowering of production of shrimp can be due to overstocking, as it is one of the predictors for yield [49]. By having a lower stocking density, a farm can obtain maximum production and high survival rate as proven in other studies [50] . High survival rate can also be attainable in small intensive ponds with best management practices [51].…”

Shrimp industry in the Philippines plays a vital role in the economy by contributing a total production in the fisheries sector of 60,000 tons of production and 7,000 tons of shrimp exported in overseas markets such as South Korea, Japan, USA and others. This study aimed to describe the various cultural and operational characteristics of a shrimp farm (Penaeus vannamei) in Davao region, and assessed the current risk and challenges experienced by shrimp farmers during the time of pandemic. This study made use of semi-structured questionnaire and focused on shrimp farmers, operators in the provinces of Davao Oriental, Davao del Sur and Davao de Oro as respondents (N=41 farmers). Results showed that small scale shrimp farming averaged 10 tons/ha per cropping; the highly intensive farms yielded 24 tons/ha per cropping. Most operators used generator machines as source of electricity to facilitate aeration accompanied with paddle wheel and blower in some farms; about 2/3 of the commercial shrimp farms used electricity from electric line. In terms of their expenditures, feed inputs have the highest cost (Php 566,700.00 for small-scale farmers, Php 5,572,900.00 for commercial farms) followed by fry (Php 144,800.00 for small-scale farmers, Php 2,080,000.00 for commercial farms) and fuel/electric bill (Php 114,000.00 for small-scale farmers, Php 4,380,000.00 for commercial farms). The average profit per ha of small holder farmers was Php 1,040,000.00. Most farmers mentioned that their shrimps experienced diseases such as white spot syndrome (60%), black gills (35%) and red tail (5%). The farmers point to contamination from water or poor water quality management which caused this disease. The study recommends that farmers should follow good shrimp aquaculture practices including water quality management.
