The implementation of partial harvesting for intensive aquaculture is a difficult undertaking for the aqua-farmers, due to the complex nature of tracking the effects of reducing density on growth, survival and eventually on productivity and profitability. In this chapter, we describe the partial harvesting decision support system (PHDSS) developed by Kam et al. (2008). The PHDSS is designed to assist aqua-farmers in determining the best harvesting strategy for a production cycle. Potential harvesting strategies include both partial harvest and single-batch harvest. The chapter navigates the readers through the system, using shrimp culture as a case study.

This study aims to analyze the profitability of vanname shrimp (Litopenaeus vannamei) cultivation using the supra intensive method and to determine the feasibility of cultivating vanname shrimp (Litopenaeus vannemei) using the supra intensive method in CV. Dewi Windu, Barru Regency. This research was conducted from March to April 2020. The sampling method used was the case study method in CV. Dewi Windu where the research goes directly to the field by taking respondents (samples) from the representative population using a questionnaire as the main data collection. Sources of data used are primary data and secondary data and then analyzed using cost and income analysis as well as business financial analysis. Based on the results of the analysis of business profits obtained in the super intensive vanname shrimp cultivation business of Rp. 3,914,733.10. Where the profit is obtained from the total revenue of Rp. 34,626,400,000 minus the total cost used of Rp. 15,050,734,400. The feasibility of Vanname Shrimp Cultivation at CV Dewi Windu was obtained from the results of the NPV, B/C Ratio, IRR, and Payback Period where each was obtained. The NPV (Net Present Value) obtained in the supra-intensive vanname shrimp culture in the next five years is Rp. 3,772,305,286. Comparison of the value of net cash receipts in the future or Net B/C ratio in the supra intensive vanname shrimp farming business is 1.1. Interest rate or IRR (Internal Rate of Return) in the cultivation of super-intensive vanname shrimp is 25.4%. As for the payback period (PP) in the cultivation of super-intensive vanname shrimp, which is for a period of less than 1.95 years or equal to 23.4 months.

Microbial load in terms of Total Coliform (TC) and Fecal Coliform (FC) were documented in the water of a shrimp culture farm at Malancha region of North 24 Parganas for a period of 36 years (1984-2019). The region receives the wastewater from the city of Kolkata. A steady hike in the microbial load (comprising of both total and fecal coliform) is noticed. The primary reason behind this rise of the microbial load is the run-off from the nearby landmasses that brings various types of wastes in the shrimp farm under investigation. The sustainability of shrimp farms in this region is under question due to the huge microbial load as revealed from the output of NAR.

In shrimp culture, various diseases, white spot syndrome virus (WSSV) in particular, has been emerging as a serious constraint affecting shrimp culture in Bangladesh. In this study, effort has been given assessing the risk factors for WSSV outbreak under which 72 farms were investigated belonging 4 Upazilas of Bagerhat (Kochua, Rampal, Fakirhat) and Khulna (Paikgacha) district of Bangladesh from January to June 2011. Major scenario depicted improved traditional culture method. PCR test has been carried out to confirm WSSV infection. About 20 factors were considered in assessing the association of WSSV outbreak. Study revealed significant correlation with some factors like accessibility of cattle (r=0.630, p≤.01) and linked up with other ghers (r=0.754, p≤.01) within a cluster (Spearman’s rho correlation coefficient test). Pearson Correlation coefficient for salinity found to have significant correlation with the risk of WSSV infection (r= -0.727, p≤.01), followed by temperature (0.624, p≤.01) and average depth (-0.618, p≤.01), however, feeding kept 30.6% farms away from the outbreak followed by sludge removal (26.39% farms). On the contrary, uses of river water directly into the ghers pose 38.9% risk of being attacked which is absolutely nill and 1.4% for the underground and rain water respectively. Disease prone months found in March to June and out of the four upazilas, Fakirhat found to be less infected due to better management. Therefore, ensuring proper gher management practice, virus free Pl, awareness buildup at the farmer level and community based farm management development can act as preventive measures in reducing the risk of WSSV infection.

The impact on coastal ecosystems of suspended solids, organic matter, and bacteria in shrimp farm effluents is presented. Sites around Bahía de Kino were selected for comparative evaluation. Effluent entering Bahia Kino (1) enters Laguna La Cruz (2). A control site (3) was outside the influence of effluents. Water quality samples were collected every two weeks during the shrimp culture period. Our data show that the material load in shrimp farm effluents changes biogeochemical processes and aquatic health of the coastal ecosystem. Specifically, the suspended solids, particulate organic matter, chlorophylla, viable heterotrophic bacteria, andVibrio-like bacteria in the bay and lagoon were two- to three-fold higher than the control site. This can be mitigated by improvements in the management of aquaculture systems.

Abstract Mexico got started in inland brackish water shrimp culture in 1996 and reported 135 ha dedicated to inland culture by 2001. Jory et al. (2003) listed 28 inland farms in Mexico. Treece (2002) described six shrimp and finfish farms in West Texas, USA that utilized salt water trapped below the ground. The aquifer that the shrimp farms use in the Imperial area (Texas) is the Cenozoic Alluvium, water remaining from the Permian Sea. All farms draw from the same source. Salinity varies from 10 ppt to 15 ppt. There are no fresh water zones in that area, and no discharge water leaves any of the farms. This water is not used in any other form of agriculture on a large scale. All soils are basically red clay in the Pecos River Basin. The farms are utilizing 'organic culture' as much as possible and they all try to stay as natural as possible with the culture techniques, to better utilize niche markets. The original research and development project in West Texas started in 1972 when two gravel pit operators decided to stock the brackish water pits with red drum and marine shrimp. Inland shrimp farms were built in Texas in the 1980s, but none were sustainable until recently. Interest was renewed after a research project was conducted in Imperial, Texas by Texas A&M University, the Texas General Land Office and the Pecos County Water District #3 in 1992. Commercial operations began to build ponds in the Pecos and Ward county area in the Pecos River Delta. An example of a 26 hectare inland saline shrimp culture facility can be seen in Pictures (Permian Sea Shrimp Company in Imperial, Texas). Multiple ponds utilize a common drain and harvest area. The white spots on each pond are the result of paddlewheel aerators.

Abstract The shrimp culture industry around Chilika Lake has expanded in the last two decades under the rationale of providing economic benefits at national, regional, community and household levels. Salinisation and pollution of agricultural land especially rice paddies by seepage usually ruin crops and render the land unsuitable for agriculture. As a result there is the decline in the yield rate, which led to the conversion of agricultural land to shrimp ponds. After the shrimp culture for some years the land will be unable to support any natural or agricultural productivity. In due course, these shrimp ponds are abandoned being fit for nothing. The lack of emphasis on enforcement of different legislation, particularly environmental legislation, has allowed the shrimp farms to operate in and around the lake using culture practices that degrade the environment. Thus, the problem with the state is not a lack of legislation, but an unwillingness or inability to enforce it. As a result of this, an established livelihood system is broken down as land with multiple agricultural uses is turned over to mono-crop production. This in turn will lead to abandoned land, which is of no use after few years.
