Abstract The Pacific white shrimp, with the largest production in shrimp industry, has suffered from multiple severe viral and bacterial diseases, which calls for a more reliable and environmentally friendly system to promote shrimp culture. The “Aquamimicry system”, mimicking the nature of aquatic ecosystems for the well-being of aquatic animals, has effectively increased shrimp production and been adapted in many countries. However, the microbial communities in the shrimp intestine and surrounding environment that act as an essential component in Aquamimicry remain largely unknown. In this study, the microbial composition and diversity alteration in shrimp intestine, surrounding water and sediment at different culture stages were investigated by high throughput sequencing of 16S rRNA gene, obtaining 13,562 operational taxonomic units (OTUs). Results showed that the microbial communities in shrimp intestine and surrounding environment were significantly distinct from each other, and 23 distinguished taxa for each habitat were further characterized. The microbial communities differed significantly at different culture stages, confirmed by a great number of OTUs dramatically altered during the culture period. A small part of these altered OTUs were shared between shrimp intestine and surrounding environment, suggesting that the microbial alteration of intestine was not consistent with that of water and sediment. Regarding the high production of Aquamimicry farm used as a case in this study, the dissimilarity between intestinal and surrounding microbiota might be considered as a potential indicator for healthy status of shrimp farming, which provided hints on the appropriate culture practices to improve shrimp production.

Secondary Information

A study on problems and prospects of shrimp production and marketing from Bangladesh on the basis of secondary information was carried out from July to October 08. Shrimp farming has emerged one of the important economic activities in Bangladesh and become the second largest export industry after garments. Shrimp aquaculture in coastal areas plays a major role providing employment, income and food security to remote coastal people where alternative livelihood options are limited. Shrimp culture system is extensive to improved extensive type with total production of 55000 mt of brackish water shrimp and 12000 mt of freshwater shrimp. In coastal Bangladesh, shrimp culture has led to many social and environmental problems. In export markets, shrimps are great but many challenges remain ahead because of increasing requirements of quality, food hygiene and development of technological and trade barriers in large shrimp markets in USA and EU countries. However, challenges lies with good aquaculture practice and competitive export, which are the effective tools for poverty alleviation and national development program for Bangladesh.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16868 Progress.

Shrimp culture in the floating cage is expected to reduce the utilization of land and its possible negative impact to the environment. The advantages of shrimp farming in the sea include the high dissolved oxygen concentration and the better meat quality. This research aimed to enhance the production performance of shrimp through the utilization of periphyton as a natural feed for shrimp. A completely randomized design with 3 treatments (in triplicates) were applied in this experiment, i.e floating cage without perishel (control), floating cage with PE perishel and PA perishel. Shrimp with body weight of 2.5 ± 0.2 g were stocked at the initial density of 2,000 shrimp in each cage, and maintained for 90 days. No significant difference was observed in the survival amongst treatments. The lowest feed conversion ratio (1.74) and coefficient of variance (3.21) were showed in treatment PA. The highest attachment and abundances of periphyton were found in treatment PA. It was concluded that the addition of perishel inside the floating cage may contribute as natural feed source for the shrimp and thus increase the production performance of shrimp.

Intensive Aquaculture

Intensive aquaculture of vaname shrimp (L. vannamei), has been known to be a favorite for aquaculture commodities in Indonesia at the last 2 decades. The purpose of this study was to determine status of financial feasibility and business sensitivity rate in intensive shrimp culture activities. The research method used in this study is a quantitative method. The data analysis used to determine of financial feasibility and business sensitivity in the form of NPV analysis, Net B/C, R/C, IRR, and payback period. Also, an analysis of assumptions about rising feed prices and decreasing production revenues for the level of business sensitivity. The results showed that the shrimp culture business was categorized as feasible and profitable with NPV value of IDR 63,417,262,006, Net B/C 29.11, R/C 2.14, IRR 42.46%, and PP 1.4 years. Sensitivity analysis shows that the business is not so sensitive to the increase of feed prices and decreased revenue, but is very sensitive if both conditions change simultaneously, but are still in the financially feasible category. So, it can be concluded based on NPV, Net B/C, R/C, IRR, and payback period indicator analysis that intensive white shrimp farming is very feasible and profitable to use with a low level of business sensitivity due to feed price fluctuations changes and uncertain operational business revenues.

Cleaning Machine

Limited water exchange shrimp culture technology is commonly used today in many shrimp farms in Vietnam to reduce water usage, input of diseases and discharge of nutrient-rich effluents into environment as well as to increase the production per unit area. However, a remaining problem in this technology is that the water quality in shrimp ponds will be reduced due to limitation of water exchange for a long period. The accumulation of inorganic components such as waste feed, bacterial deposits or other biological debris at the pond bottom will lead to low dissolved oxygen, high ammonia-nitrogen level, high fecal coliform bacteria and high turbidity which cause a severe degradation of water quality and detriment to shrimp growth and survival. To solve this remaining problem, an autonomous water-cleaning machine for shrimp ponds was designed to control the waste accumulation in the pond. This is an effective solution to replace manual cleaning methods for water quality management in shrimp farming in the coastal area of the Mekong delta of Vietnam. Especially, this technique can be used for biosecure shrimp production systems according to GMP standards to meet the objectives for sustainable development of shrimp aquaculture in Vietnam. Kỹ thuật nuôi tôm không thay nước đang được sử dụng rộng rãi ở các trại nuôi tôm Việt Nam vì giúp giảm lượng nước sử dụng, hạn chế thải nước vào môi trường và giúp tăng diện tích nuôi trồng tôm. Tuy nhiên, bản thân kỹ thuật này cũng tạo nên một sản phẩm chất thải là phân tôm, thức ăn và chế phẩm sinh học xử lý nước dư thừa. Chất thải này dần dần tích tụ dưới đáy ao tạo thành lớp bùn độc, rất thiếu ôxy và chứa nhiều chất gây hại như ammonia, nitrite, hydrogen sul-fide. Để tránh làm giảm diện tích ao nuôi do chất thải tích tụ làm tôm lảng tránh và tăng mật độ tôm nuôi trồng, thiết bị tự hành thu gom chất thải làm sạch nước trong vuông nuôi tôm đã được nghiên cứu, thiết kế và chế tạo thành công. Thiết bị đã thay thế các hoạt động làm sạch chất thải thủ công của con người, không sử dụng các nguồn năng lượng gây ô nhiễm, giảm nhu cầu về điện góp phần phát triển sản xuất tôm sạch đạt chuẩn GMP và phát triển bền vững ở các tỉnh ven biển miền Tây Việt Nam.

The Impact

Recently the shrimp farming has blooming as a crucial counterpart in the aquaculture industry which contribute the remarkable role in sea food production as well economy of the country. However, this could be fluctuated every year through several circumstances such as unfavorable (Poor water and soil quality) environmental factors. The environmental factors includes disease causing bacterial pathogens in the soil and water which causes the bacterial diseases in the aquatic animals, like this hectic problems are prevented through bioaugmentation strategies. The pond environment plays a vital role in determining the healthy culture system, but there is high risk for manipulation by bacterial community which takes care of waste generated in the system through in situ bioremediation. Due to the impact of rapidly growing bacterial diseases of shrimps throughout the world, numerous studies have been carried out to find immunostimulants, immunomodulators and biotic component that can be used against vibrio causing pathogens, and can also be used as an alternative for antibiotics. Recent research focus towards the marine resources such as microalgae, seaweed, live feeds (like artemia, copepods, rotifers), bacteriophage, and probiotics have been found to have higher potential in reducing vibriosis. Eco-based shrimp farming includes green water technology, phage therapy bio-floc technology (BFT) and integrated multi-trophic aquaculture (IMTA), these methods hold a promising alternative to antibiotics in the near future. Bacterial diseases caused by vibrios have been reported in penaeid shrimp culture systems implicating at least 14 species and they are Vibrio harveyi, V. splendidus, V. parahaemolyticus, V. alginolyticus, V. anguillarum, V. vulnificuslogei etc.
