Integrated rearing system approach in the farming of mud crab, shrimp, fish, oyster and periphyton in bracksihwater pond

Abstract

Diversification of production systems has been identified as one of the major strategies for the long‐term sustainability of brackishwater aquaculture. On the context of diversification, a 180‐day culture experiment was carried out where four farming systems were tested: monoculture of mud crab, Scylla serrata (T1), polyculture of mud crab, with mullet Mugil cephalus and shrimp Penaeus indicus (T2), polyculture of mud crab with mullet, shrimp and oyster Crassostrea cuttackensis (T3), polyculture of mud crab with mullet, shrimp, oyster along with periphyton net (T4) covering 10% of the water spread area. There was no significant difference in the growth performances of mud crab, shrimp and oyster among the treatment but a significantly higher (p < .05) final average body weight (ABW) of M.cephalus was recorded in T4 (121.19 ± 2.09 g). Production considering only the fed animals (excluding oyster) was significantly (p < .05) higher in T4 (2,115 kg/ha) compared to other treatments. The overall water quality parameters do not vary significantly (p > .05) among the treatment ponds. Although there was no significant difference in total ammonia nitrogen (TAN) and nitrite‐N, highest value was recorded in T2 (56.23 ± 39.47 µg/L and 185.53 ± 110.71 µg/L) and T1 (55.78 ± 32.26 µg/L and 180.83 ± 103.65 µg/L). The results from the current experiment based on water quality and growth of animals showed that there is no negative interaction between the mud crab and other animals stocked in the polyculture pond which indicated that polyculture provides an efficient and sustainable utilization of resources.

Effect of feeding rate on growth and feed conversion ratio in the cultivation recirculation systems of multi tropic model

“…Unlike other parameters, the FCR in this study was significantly lower (P<0.05) in feeding rate of 5% than 7.5% and 10% and all three were significantly different. The IMTA model has been recognized as a good practice for increasing aquaculture production [21], [23], [26][27][28]. As evident in the present study, the IMTA model with a recirculation system resulted in satisfactory survival, growth, and feed utilization.…”

Feasibility and compatibility of polyculture of Litopenaeus vannamei and Macrobrachium rosenbergii in the intertidal ponds

“… and remained at extremely low levels. This was probably due to the nitrification of the two species (shrimp‐prawn), as reported for the mud crab, shrimp and other animals (Lalramchhani et al, 2020). Further study will be focussed on the nitrification process, especially the nitrate accumulation.…”

“…NH + 4 -N and NO − 2 -N remained at extremely low levels. This was probably due to the nitrification of the two species (shrimp-prawn), as reported for the mud crab, shrimp and other animals (Lalramchhani et al, 2020).…”

“…Liu (2016) reported a co‐cultured system of the swimming crab Portunus trituberculatus and the ridgetail white shrimp Exopalaemon carinicauda , which resulted in production of 1429 and 1515 kg ha −1 y −1 respectively. The polyculture results of shrimp Penaeus indicus with mud crab Scylla serrata indicated that polyculture provides efficient and sustainable utilization of resources (Lalramchhani et al, 2020). Polyculture of shrimp with sea cucumber ( Holothuria inornata ) in a biofloc system also revealed a satisfactory yield without influencing the survival of H .…”

Potensi Ko-Kultur (Caulerpa lentillifera) dan Udang Windu (Penaeus monodon) di Tambak Tradisional Air Payau

“…Namun, dalam perspektif peningkatan produksi, selain manfaat ekonomis, aspek ekologis juga harus diperhatikan yang saat ini menjadi isu penting dalam budidaya berkelanjutan. Lalramchhani et al (2020) mengemukakan bahwa diversifikasi produksi merupakan salah satu strategi yang paling penting untuk mencapai keberlanjutan jangka panjang budidaya di air payau.…”
