Aim of study: To determine the effects of white shrimp (Litopenaeus vannamei) and tilapia nilotica (Oreochromis niloticus var. Spring) in monoculture and co-culture on water quality variables and production in earthen ponds during dry and rainy seasons.Area of study: A shrimp farm (total area 20 ha) at Chiripa, San Blas Nayarit, Northwest coast of Mexico (21° 37' 34.53 " N; 105° 18' 16.31" W).Material and methods: Two production cycles were performed in a completely randomized design consisting of two treatments and three replications each during rainy season (September-December) and dry season (February-May). Shrimp was the main crop and tilapia the secondary species.Main results: White shrimp (10 org/m2) can be co-cultured with Nile tilapia at a stocking high density (4 org/m2), leading to improved water quality and better utilization of nutrients in dry season than in rainy season. However, the shrimp’ highest weight was recorded in the tilapia-shrimp co-culture ponds during rainy season due to higher water temperature and better quality of live food. The mean individual weight, biomass and survival of the shrimp, in co-culture ponds were greater than those of the shrimp monoculture, in the two seasons studied.Research highlights: There was a trend towards greater concentration of nutrients in the water of the monoculture ponds and, lower dissolved oxygen and higher BOD5 in co-culture ponds in the dry season than in the rainy season.

This study was conducted to evaluate the current status of the intensive white-leg shrimp farming in earthen system and tarpaulin pond system in Tra Vinh Province by interviewing 110 farmers in Trà Vinh from May to December of 2019. The results of the study showed that an average stocking density in earthen systemand tarpaulin pond system were at 195 and 87 inds/m2 and the number of crops for earthen and tarpaulin ponds are respectively from 1 - 2 crops and 2 - 3 crops per year. The harvested shrimp size and the productivity in tarpaulin ponds (35 inds /kg; 48 tons/ha/crop) were significantly higher than those in the in earthen ponds (58 inds /kg; 12 tons/ha/crop). The net income obtained from the tarpaulin ponds model (1.760 millionVND/ha/crop) was significantly higher than that in the earthen ponds (267 million VND/ha/crop). Food change ratio in tarpaulin ponds was higher than in earthen ponds. The advantages and disadvantages of white - leg shrimp farmers in two models are also mentioned in this report.
