Fish meal replacements
Lupin seed meal and dehulled lupin seed meal are two regional proteins that can substitute significant portions of fishmeal in diets for aquaculture and commercial use. Supplementing lupin meal with other regional plants may achieve a higher substitution rate. While lupin is a suitable substitute for fishmeal, inclusion rates exceeding 100 g kg-1 are associated with progressive declines in performance.
Several sources are increasingly being considered as fish meal replacements for aquaculture. Algae oil and cultivated camelina are sustainable options. Hydrolyzed feather meal from the poultry industry is another source. However, none of these is perfect. Moreover, no single alternative protein source can completely replace fish meal. Therefore, Fitzsimmons suspects a combination of approaches that will ultimately result in an eco-friendly, fish-free feed source for aquaculture.
Impact of phytogenic feed additives on growth performance
Phytogenic feed additives for aquatic animals have been studied in many species of fish, including rainbow trout and channel catfish. These compounds have been shown to promote growth performance in fish by improving the fish’s FCR (Food Conversion Rate) and resistance to disease. However, field application of phytogenic-derived compounds is far from achieving the desired objectives. This study provides some preliminary results on the effectiveness of phytogenic feed additives for aquatic animals, including shrimp.
In a recent study, researchers investigated the effects of phytogenic feed additives on growth performance in evergreen shrimp. Digestarom, a phytogenic feed additive manufactured by Biomin in Getzersdorf, Austria, was evaluated in a 110-day feeding experiment. Steers were randomly assigned to one of three diets, containing 86.5% barley and 10.0% barley silage, along with a vitamin and mineral supplement.
Cost of fish meal replacements
In a recent study, the cost of fish meal replacements for evergreen shrimp diets was found to be 7 to 10% cheaper than conventional fishmeal sources. The study looked at different plant ingredients as potential replacements for fishmeal. Common plants that could be used as substitutes for fishmeal include pea protein, rapeseed meal, corn gluten, and corn oil. Despite these disadvantages, the study suggests that these plant ingredients are a cost-effective option for evergreen shrimp diets.
The shrimp industry represents the largest market for fishmeal in the aquaculture sector. As the largest consumer of fishmeal, it commands close attention from feed manufacturers. In fact, it has the highest demand for the ingredients and is one of the most lucrative groups in the aquaculture industry. However, with the rising costs of fishmeal, more research needs to be conducted to identify alternative sources. For instance, fish meal replacements could be an effective option for evergreen shrimp diets if they are used strategically.
Impact of PFA on growth performance
The impact of PFA on growth performance of evergreen species of shrimp was first investigated in a disease challenge system using individual 10-L biofilter-equipped tanks. This system mimicked conditions common in shrimp rearing and feeding trials. During the disease challenge trials, shrimp were randomly selected from each tank and transferred to a salinity and disease challenge facility. The feed formulations of each disease-challenged tank were controlled for salinity, temperature, and aeration.
There is a strong possibility that the inclusion of H. illucens ingredients in shrimp feed may have beneficial effects on immune and growth performance. However, previous studies have focused on other species. The present study evaluated the dietary inclusion of H. illucens larvae on juvenile L. vannamei to assess their growth performance and resistance to salinity stress. The larvae were also challenged with V. parahaemolyticus (V. parahaemolyticus), and white spot syndrome virus (WSSV).
Impact of PFA on feed efficiency
In this study, the effect of PFA on shrimp growth was assessed by examining water quality in four different ponds. During the first pond preparation stage in September, water samples were collected and stored at 4 degC. At the second pond preparation stage in October, water samples were collected again at 50 cm depth and then transported to the Department of Environmental Science Laboratory at Chulalongkorn University.
The researchers determined that approximately 35% of the nitrogen consumed by the shrimp was recovered from the body. However, this was only one of many variables that impacted the nitrogen content in the water. Some studies indicated that up to 52% of N was lost through denitrification and ammonia volatilization. In most cases, these losses are indirect and cannot be measured. However, the results are indicative of an important effect of PFA on the growth of evergreen shrimp.
Impact of PFA on feed cost
Phytogenic feed additives, such as Digestarom P.E.P. MGE, improve the efficiency of aquafeeds and reduce feed costs. These additives improve the physiological competence of shrimp, which has important implications for aquafeed cost. They can also improve growth performance and feed efficiency. Phytogenic feed additives were used for a study on Pacific white shrimp. Here, we discuss the benefits and drawbacks of phytogenic feed additives.
Phytochemical analysis of PFA in aquatic feeds revealed that these additives improved the performance of juvenile white leg shrimp. This feed improved their weight gain, specific growth rate, and protein efficiency ratio. Using an electron microscope, researchers also observed that shrimp fed with PFA-enriched feeds had more uniform pellets and improved microvilli structure. The effects of PFA on shrimp feeds have been studied in other species.
