Abstract The shrimp (Penaeus monodon), locally known as bagda, is known as white gold for its high economic value in Bangladesh. The shrimp sector of Bangladesh is seen as having become important in economic terms, contributing significantly to foreign exchange earnings and employment generation in rural areas. P. monodon culture is practiced in the Bagerhat, Chokoria, Cox's Bazar, Khulna, Moheshkhali, Shatkhira and Teknaf regions and recently has been introduced in some coastal areas of Noakhali district. Three culture systems are found in Bangladesh, i.e. traditional, improved traditional and semi-intensive with production rates of 150-200, 250-400 and 2,000-2500 kg ha-1, respectively. Seed is collected from natural sources and is produced in hatcheries. There are 44 penaeid shrimp hatcheries in Bangladesh. The present shrimp fry production is 3.05 billion. More than 200,000 people are engaged in shrimp fry collection and marketing and more than 350,000 people are engaged in shrimp farming. Ancillary industries like shrimp hatcheries, feed industries, ice factories, processing factories, net industries and shrimp culture apparatus industries provide direct employment for 25,000-30,000 people. Adverse environmental impacts reported are reduction of grazing land and saline water intrusion due to mismanagement but these could be overcome by introducing environmentally friendly shrimp culture. As the climate of Bangladesh is favourable for P. monodon culture, it is necessary to give more attention to improve it as it will open a new horizon in the economy of the country.

Abstract In crop rotation different crops may be cultivated within the same year to rejuvenate the environment and reduce pests and diseases. Crop rotation in shrimp farming is not popular in Bangladesh as the shrimp bagda (Penaeus monodon) is much more profitable than growing rice or farming brackish water fish. In traditional and improved traditional farms, it is usual practice to stock seed and harvest shrimp year-round. Viral disease occurred in the 1990s and caused mass mortality of penaeid shrimp. To minimise the risk of disease, there is a need to apply crop rotation techniques of shrimp with rice and finfish on farms in coastal areas, as is carried out by some farmers. Shrimp culture is generally done in the dry season (February-June) when water salinity increases (>10ppt) and ceases in the rainy season (July-August) when salinity decreases (<5ppt) because of heavy rainfall. Depending on salinity, some farmers produce two crops. During February-June they produce shrimp and subsequently they produce rice or freshwater fish.

Distribusi spasial kelimpahan udang windu berkisar antara 10-130 ekor/m2 (10-167.000 g/ha). Analisis aspek status pemanfaatan, degradasi habitat (penebangan liar, pembukaan tambak, dan sedimentasi), perkiraan dan evaluasi resiko, serta faktor-faktor yang mendukung diantaranya respon masyarakat dan kesiapan sistem sosial merupakan masukan dalam menentukan konservasi sumber daya udang windu. Oleh karena itu, dalam upaya menjamin kelestarian sumber daya udang windu di alam serta keberlanjutan usaha budidayanya, perlu dilakukan langkah-langkah pengelolaan dan konservasi sumber daya udang windu yang rasional, seperti (a) pengendalian dan pemulihan degradasi lingkungan melalui pengendalian erosi bagian hulu-hilir, dan menjaga dan merehabilitasi hutan mangrove, (b) pengendalian penyebaran penyakit dengan pendekatan kehati-hatian untuk pengembangan budidaya udang vanamei, (c) pengendalian penangkapan juvenil udang windu melalui pelarangan beroperasi alat tangkap sejenis trawl (pukat langgih dan pukat layang), dan (d) revitalisasi dan pengembangan kelembagaan nelayan.Indian tiger prawn (Penaeusmonodon) is one of the main shrimp commodities and has high economic value. East coastal waters of East Aceh district is known as one of the main producer of tiger prawns with the best quality. On the other hand the rate of exploitation of tiger shrimp is very high. This issue is therefore need to be a addressed further. The purpose of this study is, therefore, to assess the management activities needed to conserve tiger shrimp in East Aceh. Penaeidae post larvae density in Aceh Timur ranges from 0-214 ind/1,000 m3 and juvenile stock density ranges from 0,245-49,419 kg/km2, where the highest density is in Kuala Arakundo and Kuala Peureulak. The Spatial Abundance Distribution of indian tiger prawn ranges from 10 to 130 ind./m2 (10-167,000 g/ha). Analysis of aspects of utilization status, habitat degradation (illegal logging, sedimentation, land clearing for aquaculture), risk estimation and evaluation, and factors are inputthat support conservation of tiger shrimp resources. Therefore, in an effort to ensure the sustainability of tiger shrimp resources in the wild and the sustainability of its cultivation business, it is necessary to take steps to manage and conserve rational tiger shrimp resources.such as (a) controlling and restoring environmental degradation through upstream-downstream erosion control, and safeguarding and rehabilitating mangrove, (b) controlling the spread of diseases with precautionary approach to the development of vanamei shrimp farming, (c) controlling the capture of indian tiger prawn juveniles through the prohibition operates of bottom trawling (pukat langgih and pukat layang), and (d) fisherman revitalization and institutional development.

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.

Shrimp culture has been developed during the last three decades and the production of farmed shrimp reached its peak. However, the shrimp production was decreased all over the World including in Asian Countries because of the mass mortality due to the outbreak of several diseases predominantly White Spot Syndrome Virus (WSSV) which caused extensive economic damage to the shrimp culture industry. Various Polyculture technologies of shrimp with shellfish, finfish or seaweeds have been implemented to reduce economic damages by mass mortality of shrimp. The present study was conducted with Tiger shrimp Penaeus monodon and Pacific white shrimp Litopenaeus vannamei through Polyculture operation to determine optimum stocking ratios for induction of best performance and highest production rates. Initially, the experiments were conducted with different ratios and combinations of stocking densities 1:1, 2:1 and 1:2 ratios of Penaeus monodon and Litopenaeus vannamei with control group feed with commercial feed, the other group certain Probiotic bacteria such as Bacillus licheniformis and Lactobacillus rhamnosus added in feed, the third group both the Probiotic bacteria and the addition of external Carbon source from sugarcane molasses in the form of Bioflocs for 100 days. To ascertain further interaction of ratios influence, 20:10, 20:12, 20:15 ratios of stocking and Monoculture experiments were conducted. In both the experiments the Survival rate, Final body weights, Weight Gain, Feed conversion ratio, Specific growth rates, Average daily growth rates, Protein efficiency ratio, and Productivity rates were significantly different (P<0.05) in all the different treatments both for P. monodon and L. vannamei. From the results obtained 20:10 ratio of P. monodon and L. vannamei was considered as the best ratio of stocking, which yielded the highest production rates in all the Control, Probiotic added and both Probiotic & Biofloc added groups. The results obtained in the present study clearly demonstrate that the rearing of taxonomically similar species with optimum stocking ratios seems to improve the efficiency of shrimp farming and substantially increasing the production rates. So, this polyculture of P. monodon and L. vannamei can be considered as an alternative approach towards the establishment of sustainable shrimp farming activity which will yield good economic returns.

Context: The study was conducted under the technical support of ATDP-II in Bagerhat District, from July to November 2005 on traditional, closed, and semi-intensive culture packages of penaeid shrimp (Penaeus monodon). Objective: The objective of the study was to compare the management, technical and economic aspects of three different shrimp culture packages. Materials and Methods: Post larval nursing was done for 30 days at a density of 50 PL/m2. Culture was done for 120 days at a density of 2.11, 7.37 & 11.56 individuals/m2 in traditional, closed, and semi-intensive ponds respectively. Shrimp PL were fed CP feed (40 % protein) at a rate of 2kg for 100,000 PL, but no supplementary feed was used in traditional ponds. Results: The highest average daily growth (0.263±0.026 g/day) was found in traditional culture; while in closed, and semi-intensive system it was lower (0.226±0.023 and 0.239±0.022 g/day respectively) due to high stocking density and feed competition. Survival rates were found 49.14±5.94, 57.94±8.01 and 60.07±10.98 % which yielded 327.23±24.14, 1158.07±134.76, 1991.57±232.70 kg/ha in traditional, closed, and semi-intensive ponds respectively. Net income was calculated 47932.18 Tk/ha from traditional, 178779.2 Tk/ha from closed, and 312736.8 Tk/ha from semi-intensive culture. Conclusion: The study suggests that instead of horizontal expansion of traditional shrimp cultivation, healthy management and improved culture technique are very much important to increase shrimp production in Bangladesh.

White feces syndrome (WFS) is an emerging problem for penaeid shrimp farming industries in South East Asia countries. Outbreaks began in cultivated shrimp Penaeus (Penaeus) monodon, and Penaeus (Litopenaeus) vannamei and spread progressively worldwide, although the disease's cause was unknown. In 2011 a case definition for AHPND (as acute hepatopancreatic necrosis diseases) and white fecal syndrome (WFS) were reported. The presence of white feces floating on water and clinical symptoms include pale empty gut region, reduced growth, movable shell, and black discoloration. The pacific white shrimp, Litopenaeus vannamei, with the major shrimp cultivable species globally, is currently in danger by a severe disease- WFS, which causes serious losses worldwide. It has been confirmed that the causative agent of WFS/AHPND is a bacterium that is a pathogen - probably Vibrio parahaemolyticus. This bacterium currently reported has acquired plasmids that encode lethal binary toxins PirA/PirB causing rapid death of infected shrimp. Additionally, this plasmid acquired some virulence factor which is directly related to pathogenicity. Further rapid diagnostic tests for early detection of WFS/AHPND pathogens will promote the production of hatchery and pond maintenance and contribute to the long-term explication of the disease's various aspects.

Satkhira is a coastal district of Bangladesh where lives of millions of people are transforming due to natural hazards and anthropogenic stimuluses, specifically water bodies are facing the bulk of the transformation owing to salinity. The study area of this research includes part of Satkhira Sadar and the work is done based on Betna river influenced zone. Sundarban and the Bay of Bengal are close to this river and its highly influenced by saline water. The natural pristine environment of the area went through major changes during the last few decades, especially after the 1980’s because of human interventions as well as natural causes. This research was an attempt to find out the transformations that took place in the area with remotely sensed imagery of 2018 and toposheet map of 1982, the underlying reasons of change and their consequences. The collected data were analyzed with Remote Sensing and Geographic Information System (GIS) software’s for better interpretation and an in-depth understanding. Features which came into consideration frequently are river, shrimp farms, settlement, agriculture, embankment, salinity intrusion, increasing population, frequent hazard and riparian vegetation. The outcome of the work tells that the change in land use occurred mainly because of shrimp farming and salinity intrusion while Betna river took the major blow. Although economically beneficial, shrimp culture created a saline environment and modification of water bodies resulted in frequent waterlogging and escalated salinity in the area previously known as freshwater zone. While Bangladesh is scare in land resource, the coastal area such as the study site of this research is even more stressed owing to climate change and recurring natural hazards. Propositions are made at the end of the work to use the presented data and information mentioned in this study by corresponding authorities.

Abstract In Thailand, marine shrimp was traditionally produced extensively for decades in coastal ponds. The insatiable global demand for shrimp products in recent years intensified and expanded shrimp culture in Thailand throughout the 1990s. Few regulations or guidelines were imposed on developing coastal land for shrimp farming. The boom resulted in rapid degradation of the coastal environment and widespread disease outbreaks, causing repeated crop failures in shrimp culture. In contrast, shrimp cultured in low-salinity ponds away from the coast experienced great success. As a result, thousands of hectares of rice paddies in the Thai heartland distant from the seacoast were converted to low-salinity shrimp farming. Large quantities of high-salinity brine (100-200 ppt) were transported from coastal salt pans to fill inland ponds to a salinity less than 5 ppt. Other than the salinity difference, low-salinity shrimp culture was generally similar to that in the coastal ponds. Shrimp were stocked at high density (50-100 PLs m-2) in a closed system. The shrimp production commonly exceeded 10 t ha-1 crop-1 in 3-4 months. During the peak period, shrimp production from inland areas accounted for nearly 40% of total annual production of shrimp at 200,000 t in Thailand. As the economic gain from shrimp production was more than 50-fold that of the rice crop, shrimp culture was regarded as a bonanza for debt-ridden rice farmers. However, inland shrimp farming was short-lived, as the Thai government banned the practice in 1993 on the grounds that it led to salination of soil and groundwater, and ultimately jeopardized the national rice bowl. Despite the ban, low-salinity shrimp farming still exists in areas where intrusion of natural seawater occurs. However, with persistent disease problems encountered in culturing native Penaeus monodon, the exotic white shrimp (Litopenaeus vannamei) has become the major species.

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.
