Abstract Hai Phong province is one of the main shrimp culture areas in north Vietnam. Its climate is influenced by two monsoon regimes. The April-September southwest monsoon is wet and hot, and the temperature is suitable for shrimp culture. The October-March northeast monsoon is dry and cold, and the temperature is not suitable for shrimp culture. Different shrimp farming systems take place along the entire coast depending on socio-economic and climatic conditions, seed availability, and farming methods to minimize the operating risk. The main cultured species in Hai Phong is black tiger shrimp, Penaeus monodon. The shrimp are either cultured in monoculture or integrated or cultured alternatively with mud crab (Scylla serrata), greasyback shrimp (Metapenaeus ensis)and seaweeds (Gracilaria gracilis and G. blodgettii). The main crop of black tiger shrimp is from April to September, when about 15% of farms practice integrated shrimp-seaweed culture and 85% of farms practice shrimp monoculture. Additional crops of shrimp or mud crabs are cultured during other months from September to March, while seaweed production is integrated with shrimp or crabs all year. Thus, four main shrimp farming systems can be found in Hai Phong: Single-crop shrimp farming, double-crop shrimp farming, shrimp-crab rotation farming, and integrated shrimp-seaweed-crab farming.

This study aimed to determine the influencing factors on the yield loss due to diseases in black tiger shrimp (Penaeus monodon Fabricius, 1798) cultured in Soc Trang province. Data for the study were collected by interviewing 334 households farming black tiger shrimp in Soc Trang province in 2017. Descriptive statistical analysis was employed to evaluate the current situation of yield, disease and yield loss due to diseases in black tiger shrimp culture of households. Multiple linear regression analysis was used to determine the factors in influencing the yield loss of black tiger shrimp due to diseases. The results showed that the average black tiger shrimp yield fluctuated from 0.54 to 3.28 tons/ha/crop. The household percentage affected by black tiger shrimp diseases was from 33.3% to 90.8%. The percentage of yield loss due to diseases was between 34.6 and 74.2%. The influencing factors (variables) on the yield loss due to diseases included: being a member of black tiger shrimp culturing cooperative; application of trained techniques for shrimp culture and employment of tested post larva (negative correlation with the yield loss in all culture models: reformed extensive culture, semi-intensive culture and intensive culture). For semi-intensive culture and intensive culture, the yield loss due to diseases way negatively correlated with farmer's education degree, employment of accumulation pond and the total pond area for shrimp culture of household whereas farmer's age positively correlated with farmer's age.

Tiger Shrimp

Abstract Shrimp farming in Thailand has evolved from traditional extensive to modern intensive systems and the predominant species was the indigenous, black tiger shrimp, Penaeus monodon. With current annual production approaching 400,000 t, intensive shrimp culture has saturated the available coastal areas along the Gulf of Thailand and the Andaman Sea, including estuaries, bays, tidal creeks, open coast and mangrove swamps. At one time shrimp farming spread to inland areas in the Central Plain. Despite its success, the shrimp farming industry has encountered a host of major problems, e.g. persistent disease outbreaks, broodstock quality, deterioration of pond and natural environment, and international trade barriers. In response to disease and water quality problems, protocols for pond management have evolved from an open system with frequent water exchange to semi-closed to closed systems, with little or zero water exchange during the grow-out cycle. Facing unshakable viral diseases stemming from contaminated broodstock and wild carrier organisms, farming of the indigenous species, P. monodon, came to a halt during early 2000. It was replaced by the exotic white shrimp, Litopenaeus vannamei, which is now the predominant species cultured in Thailand. The culture of black tiger shrimp may become history due to disease and seed quality problems; the white shrimp will become the dominant species in most parts of Asia. The Thai shrimp culture industry is advancing towards maturity and sustainability with the following measures: *advancement in production of quality seed through a few nucleus breeding centres, especially in specific pathogen free and genetic improvement technologies *better understanding and prevention of diseases through adoption of bio-security measures *adoption of better management practices, product certification and traceability.

The Village

Shrimp cultured in Purworejo Village begun in the 1980s. Productivity of shrimp farming in this region, had experienced a peak of success in 1998 with an average production of 200 kg / ha with black tiger shrimp (Penaeus monodon) as the main commodity. Productivity decreases to 120kg / ha then occur due to decreasing environmental quality and susceptible post larvae to disease infections. One effort to increase the productivity of ponds can be done by switching the cultivation of black tiger shrimp to Pacific white leg (Litopenaeus vannamei) shrimp. The purpose of this study was to study the feasibility of semiintensive Pacific whiteleg shrimp cultured. This research was carried out in two shrimp farmer groups namely Sido Makmur and Lestari Gemilang located in Purworejo Village, Pasir Sakti District, East Lampung Regency. The type of research used is a case study and uses descriptive tests. The results showed that Pacific white leg shrimp cultured can produce 10,804,45 kg/3 ha and achieve a profit of Rp. 407.025.500 with a net B/C of 1,7. Moreover, black tiger shrimp culturehas reached 725 kg/5 ha with a profit of Rp. 13.660.000 with net B/C of 1,2. This study concluded semiintensive Pacific whiteleg shrimp is profitable compared toblack tiger shrimp cultured. It is also feasible to be developed by the village community.

Salah satu program dari Gubernur Sulawesi Selatan periode 2018-2023 adalah mengembalikan kejayaan udang windu di Sulawesi Selatan. Telah dilakukan kegiatan yang bertujuan mengetahui performa budidaya udang windu di tambak pembudidaya yang dilaksanakan pada musim kemarau tahun 2019 di Kecamatan Marusu Kabupaten Maros. Kegiatan budidaya udang windu teknologi tradisional plus dilaksanakan di tambak Dusun Kurilompo, Desa Nisombalia Kecamatan Marusu Kabupaten Maros. Sebanyak enam petak tambak pembudidaya ditebari tokolan udang windu dengan padat penebaran dari 10.000 sampai 30.000 ekor/ha. Setelah dipelihara selama 69 sampai 80 hari dilakukan panen dan selanjutnya dilakukan penentuan sintasan, bobot rata-rata, produksi udang windu, dan rasio konversi pakan (RKP). Data yang diperoleh dianalisis secara deskriptif. Hasil kegiatan menunjukkan bahwa kualitas air di tambak Kecamatan Marusu, Kabupaten Maros pada musim kemarau dicirikan dengan salinitas yang berkisar antara 36,63-69,40 ppt; suatu kondisi yang tidak optimal untuk budidaya udang windu. Pada saat panen didapatkan sintasan udang windu dari 27,57% sampai 66,67%; bobot rata-rata dari 14,29-40,00 g/ekor; produksi dari 90,1-800,0 kg/ha/musim; dan RKP dari 0,54:1 sampai 2,10:1. Disimpulkan bahwa budidaya udang windu di tambak bersalinitas tinggi di daerah ini merupakan penyebab utama rendahnya sintasan, bobot rata-rata, produksi udang windu, dan RKP. Direkomendasikan bahwa perbaikan budidaya udang dengan menjaga tingkat salinitas dalam nilai optimal harus disosialisasikan kepada pembudidaya udang windu di daerah tersebut.One of the main aquaculture development targeted by the South Sulawesi Province for the period 2018-2023 is to restore the glory of tiger shrimp farming in South Sulawesi. The recent study was carried out to uncover redevelopment opportunities of tiger shrimp culture and determine the performance of tiger shrimp culture in the farmers’ ponds. The study was performed during the dry season in Marusu Subdistrict Maros District, in 2019. Traditional plus tiger shrimp farming activities were carried out in the ponds of Kurilompo Subvillage, Nisombalia Village, Marusu Subdistrict, Maros District. A total of six brackishwater ponds were stocked with tiger shrimp fingerling with stocking densities of 10,000-30,000 ind./ha. After being cultured for 69 to 80 days, the shrimp were harvested and measured their survival rate, average weight, production of tiger shrimp, and feed conversion ratio (FCR). The data obtained were analyzed with descriptive statistics. The results showed that water quality in brackishwater ponds of Marusu Subdstrict Maros District, in the dry season is characterized by salinity ranging from 36.63 to 69.40 ppt, a condition that is not optimal for tiger shrimp culture. At harvest, the survival rate, average weight, production, and FCR of the farmed average tiger shrimp were 27.57%-66.67%, 14.29-40.00 g/ind., 90.1-800.0 kg/ha/season, and 0.54:1-2.10:1, respectively. It is concluded that the culture of tiger shrimp in the brackishwater ponds with high salinity in this area is the primary cause of poor survival rate, average weight, production of tiger shrimp, and FCR. It is recommended that culture shrimp improvement via maintaining salinity level within the optimal values has to be disseminated to the fish farmers in the area.
