Selection of intensive shrimp farming technology for small farmers with analytical hierarchy process: a case for whiteleg shrimp (Litopenaeus vannamei)

Abstract

Whiteleg shrimp (Litopenaeus vannamei) is one of the important aquaculture commodities. This is due to high demand and farming with high stock densities. However, whiteleg shrimp farming is generally large scale, so that farmers with small capital cannot carry out business activities. In this paper, an intensive assessment of four whiteleg shrimp technologies has been carried out with seven criteria. Four intensive shrimp farming technologies are biofloc technology, supra intensive, shrimp farming in mini scale with tarpaulin (BUSMETIK), and Recirculating Aquaculture System (RAS). Seven criteria that used in the assessment are affordability of capital and operational costs on a mini scale, minimum land area for shrimp farming, dependence on the location of raw water sources, environmental friendly, productivity, energy consumption, and biosecurity. The assessment was carried out using the Analytical Hierarchy Process (AHP) method to assess the compatibility of different technologies to low investment. The results of the AHP method show that RAS is ranked first for intensive shrimp farming technology for small farmers. Then followed by supra intensive, BUSMETIK and biofloc technology. Most of the criteria used in the AHP calculation are the advantages that RAS is very suitable for small farmers.

Study of suitability location of eel (Anguilla sp) culture in Sukabumi region, West Java province

“…The zero scores are the constrained ones. Location of raw water sources and environmental friendly is the first criteria for aquaculture assessment [6]. The result of region scale suitability analyses is then brought into site scale suitability analyses to get the detail of location which suitable for Anguilla sp to grow out.…”

“…High rainfall allows the location to have sufficient water sources for aquaculture. Location of raw water sources and environmental friendly is the first criteria for aquaculture assessment [6].…”

PRODUCTION OF SHRIMP IN INTENSIVE AQUACULTURE SYSTEM OF VANAME SHRIMP (Litopenaeus vannamei) USING DIFFERENT CULTURAL SLUDGE MANAGEMENT METHODS

“…CRS biasanya dilengkapi dengan kolam pengendapan (Ray & Lotz, 2017;Permana et al, 2019). Sejalan dengan pernyataan Supono, (2017), air buangan dari tambak dengan system CRS diolah kembali melalui kolam pengendapan, kolam perlakuan secara biologi (biofiltration pond), dan kolam rekondisi (reconditioning pond) dengan (protein sekimer), sebelum masuk ke kolam budidaya (culture pond) (Zulkarnain, 2020;Hastuti et al, 2018).…”

Pengaruh Padat Tebar dan Penggunaan Injektor Venturi terhadap Laju Pertumbuhan Udang (Litopenaeus Vannamei) dalam Bak Beton

“…Beberapa tahun terakhir, sistem produksi udang Vannamei Litopenaeus vannamei di Indonesia mengalami perubahan, dari sistem ekstensif atau tradisional menuju sistem intensif dan bahkan hingga supra intensif, yang ditandai dengan penggunaan teknologi dan padat tebar tinggi. Menurut Zulkarnain et al (2020), sistem intensif memiliki karakter jumlah pada tebar antara 110 -550 udang m -2 dan supra intensif memiliki padat tebar lebih dari 500 udang m -2 . Terdapat beberapa kelebihan dan kekurangan ketika melakukan produksi dengan sistem padat tebar tinggi.…”
