“…Tilapia feed is cheaper and, because it is extruded and floats in the water column, tilapias can eat fast without competing with shrimp, which are grazing at the bottom of the pond. Shrimp eat almost everything they find in the environment, especially algae, detritus and other small organisms (Kent et al, 2011;Viau et al, 2012). By this strategy, shrimp feed on detritus settled from above, on bacterial film and also on uneaten feed particles which sink to the bottom.…”

-The objective of this work was to evaluate the performance of Pacific marine shrimp (Litopenaeus vannamei) and tilapia (Oreochromis niloticus), in a polyculture in tanks subjected to different stocking densities and feeding strategies, in comparison with monoculture. Two experiments were performed, at the same time, in a completely randomized design with three treatments and four replicates each. Treatments for experiment I were: monoculture with 10 shrimp per m² (10S:0T); polyculture with 10 shrimp and 0.5 tilapia per m² (10S:0.5T); and polyculture with 10 shrimp and 1 tilapia per m² (10S:1T). Shrimp was the main crop, and feed was provided based on shrimp biomass. Treatments for experiment II were: monoculture with 2 tilapia per m² (2T:0S); polyculture with 2 tilapia and 2.5 shrimp per m² (2T:2.5S); and polyculture with 2 tilapia and 5 shrimp per m² (2T:5S). Tilapia was the main crop, and feed was provided based on fish requirements. In the experiment I, tilapia introduction to shrimp culture resulted in lower shrimp growth and poor feed conversion rate. In experiment II, shrimp introduction to tilapia culture did not interfere with fish performance. Polyculture is more efficient with the combination of 2 tilapia and 2.5 or 5 shrimp per m² and feed based on fish requirements.

“…It is widely accepted that microalgae are actively taken up by shrimp larvae, and play an important role in nutrition at that life stage; however, it is uncertain whether juveniles and adults do actively feed on microalgae as well. Some reports suggest that microalgae are found in their gut because shrimp accidentally ingest them together with debris [11,12].…”

“…It is widely accepted that microalgae play an important role in larval nutrition of shrimp; however, it is uncertain whether juveniles and adults feed on microalgae. Some reports suggest that microalgae are found in their gut because shrimp accidentally ingests them together with debris (Marinez-Cordova and Pena-Messina 2005; Kent et al 2011). The microalgae that are usually used as feed of peneids larvae are among different genus, including Chaetoceros spp.…”

The larvae of the Pacific white shrimp Litopenaeus vannamei are fed, from the stage of protozoea I until to protozoea III (PZ III), with microalgae. The survival rate, duration of the terms of Z I -Z III and total length of protozoea larvae (PZ) of L. vannamei were survived. The shrimp larvae fed with the six treatments of microalgae (Chaetoceros muelleri, Isochrysis galbana, Tetraselmis tetrathele, C. muelleri : I. galbana, C. muelleri: T. tetrathele and I. galbana: T. tetratheie). The biochemical composition (protein, carbohydrate, lipid and energy) of the algae and the larvae fed those algae were also measured. The largest sizes were recorded for larvae fed with the mixture C. muelleri and I. galbana (4.35 mm) and smaller sizes were observed on larvae fed with I. galbana (3.04 mm) (P \ 0.05). The larvae fed with mixture T. tetrathele and C. muelleri (88.42 %) and I. galbana and T. tetrathele (84.50 %) had the highest survival in experimental treatments. The lowest time for development was observed in larvae fed with mixture of T. tetrathele and C. muelleri (92.6 h). The larvae fed with mixture I. galbana and T. tetrathele had the highest protein and carbohydrate levels as compared with other treatments. Also highest lipid level and gross energy were shown in larvae fed with mixture C. muelleri and I. galbana (P \ 0.05). The results showed that L. vannamei larvae fed with C. muelleri and the mixed diets containing this species (C. muelleri ? Isochrysis sp., C. muelleri ? Tetraselmis sp.) had the highest growth and survival among treatments.
