“…Several factors may affect shrimp feed intake, including water quality (temperature, dissolved oxygen, and nitrogen compounds), diet composition, energy, and feed attractiveness and palatability (Kureshy and Davis, 2002;Cuzon et al, 2004;Nunes et al, 2006). All treatments resulted in the same apparent feed efficiency, suggesting a similar feed conversion in the tissues of animals.…”

“…All treatments resulted in the same apparent feed efficiency, suggesting a similar feed conversion in the tissues of animals. Therefore, the low final weight and weekly gain of shrimp fed a diet with 100% replacement of fishmeal may have resulted from lower food intake because high concentrations of plant ingredients reduce attractiveness and palatability (Nunes et al, 2006;Amaya et al, 2007a,b).…”

-This study aimed to assess the final body weight, weekly weight gain, yield, apparent feed efficiency, protein efficiency ratio, and feed intake of the Pacific white shrimp (Litopenaeus vannamei) fed four diets containing different levels of soy protein concentrate (SPC) as a replacement for fishmeal, reared in a super-intensive biofloc system. Diets consisted of replacing 209 g kg −1 fishmeal at 0, 33, 66, and 100% SPC. Shrimp were raised in a biofloc system using twelve experimental units stocked with 250 shrimp m −3 under constant aeration (O2>5mg L −1 ) and temperature (29±0.5 °C). No significant differences among treatments were observed based on water quality parameters. Shrimp fed diets with 0 and 33% substitution exhibited the highest weekly growth (1.88 and 1.79 g per week) and final weights (15.2 and 14.7 g) compared with shrimp fed the 66 and 100% replacement. A lower feed intake was observed for shrimp fed the 33% SPC diet (3.18 kg per experimental unit) compared with 0% replacement (3.62 kg). Shrimp fed the 33% replacement achieved a similar performance and lower feed intake than animals fed diet without replacement.

“…The feed intake of diets with high levels of protein replacement was lower in this study ( Figure 1B), which is likely to have contributed to the reduction in shrimp growth. Diets formulated with high levels of soybean-derived ingredients may present palatability problems (McGoogan and Gatlin 1997;Nunes et al, 2006). The removal of specific carbohydrates that occurs in the processing of soybean protein concentrate may reduce palatability, which is frequently reported when vegetable protein sources are used for aquatic species (Forster et al, 2002).…”

-The objective of this work was to evaluate the performance of Litopenaeus vannamei fed different levels (0, 25, 50, 75, and 100%) of soybean protein concentrate (63.07% crude protein, CP) to replace fish meal-by product (61.24% CP). The study was conducted in clear water in fifteen 800 L tanks equipped with aeration systems, constant heating (29 ºC), and daily water exchange (30%). Each tank was stocked with 37.5 shrimp/m 3 (3.03±0.14 g). Feed was supplied four times a day, at 6% of the initial biomass, adjusted daily. After 42 days, the weight gain of shrimp fed diets with 0 and 25% protein replacement was higher than that observed in shrimp fed 100% replacement, and there were no differences among those fed the other diets. Feed efficiency and survival did not differ among shrimp fed different protein replacements. There was a negative linear trend for growth parameters and feed intake as protein replacement with soybean protein concentrate increased. Fish meal by-product can be replaced by up to 75% of soybean protein concentrate, with no harm to the growth of Pacific white shrimp.

“…It has been demonstrated that squid meal acts as a stimulant, increasing food consumption in Homarus gammarus (Mackie & Shelton 1972), Penaeus stylirostris and P. setiferus (Fenucci et al 1980), P. monodon (Smith et al 2005), and Litopenaeus vannamei (Nunes et al 2006). Similarly, shrimp protein hydrolysates stimulate feed consumption in C. quadricarinatus (Arredondo-Figueroa et al 2013).…”

“…At the beginning of each assay, juveniles were maintained in the acclimation chamber for 10 min as in Nunes et al (2006). After each trial, water was discarded completely, the aquarium was washed with tap water and refilled with new filtered water.…”
