Their crab diet
, largely responsible for their delicate flavor, makes them the favorite of many locals.
Between June and September 2013, the prey selections of green crabs were documented using mesocosm feeding experiments and green crab diet through stomach content analyses.
In addition, the average number of prey groups per crab was quantified to describe individual crab diet diversity in the short term (Stevens et al.
Green crab diet preferences and ecological impacts are qualitatively similar on different continents and ocean basins (Grosholz & Ruiz 1996), which may allow predictions of the influence of their presence.
Along with estimated proportions of protein, fatty acids, vitamins, and minerals, cellulose and chitin were included due to the high amounts of segmented invertebrates and detritus in the natural blue crab diet
. Although individuals did quite well with large amounts of cellulose in the diet, increasing amounts of chitin produced a decrease in overall growth and the number of molts (Fig.
The actual amount to be added to the Cu content of the raw materials was calculated to obtain a similar final concentration to a crab diet
according to Cerezo Valverde et al.
arenaria were a large component of green crab diet
in both May and August.
The application of a combination of rendered animal protein ingredients to replace FM protein in juvenile horseshoe crab diets
may have economic and nutritional benefits, but more study is needed to define the optimal level for replacement of FM (Schreibman & Zarnoch 2009, Tzafrir-Prag et al.
Commercial hermit crab diets
are readily available.
Correlative studies of mangrove crab diets
have associated high-preference foods with either high or low N content (Camilleri 1989, Micheli 1993b).
At the end of feeding experiment, the results showed that supplementing crab diets
at 1% and 3% is necessary for better body weight gain, molting frequency, and concomitantly reduced second to third molting intervals of the crabs (P < 0.05).
