To Determine the Efficiency of Different Fresh Diets in Improving the Spermatophore Quality of Banana Shrimp Penaeus merguiensis (De Man, 1888)

Effects of polychaetes (Perinereis nuntia) on sperm performance of the domesticated black tiger shrimp (Penaeus monodon)

“…were very different from those found in the sand polychaetes (P. nuntia) used in this study (Memon et al, 2012;Wouters et al, 2001). For instance, opposite to our result, protein content in the marine polychaete (Sabellaria spp.)…”

“…For instance, opposite to our result, protein content in the marine polychaete (Sabellaria spp.) is lowest (Memon et al, 2012). The proportion of AA: EPA: DHA in the marine bloodworm (1: 7.1: 3.1) was also different from ours (Wouters et al, 2001).…”

“…polychaetes, and Anadara granosa cockle) for 6 weeks (Memon et al, 2012). The percentage of the weight increase of the banana shrimp was highest when fed with polychaetes (7.4%), followed by squid (6.9%) and cockle (3.3%), respectively (Memon et al, 2012).…”

“…The significantly higher spermatophore weight and total sperm counts in the polychaetes-fed group found in this study agree with the previous reports using live feeds. For instance, spermatophore weight and total sperm count were significantly increased when the banana shrimp (P. merguiensis) fed with polychaetes, squid, or cockle for 3 and 6 weeks (Memon et al, 2012). Similarly, in the white shrimp (Litopenaeus vannamei), the total sperm count was increased after a 56-day feeding trial with a combination of 60% squid and 40% marine bloodworms (Perez-Velazquez et al, 2003).…”

“…Effects of the live feeds on male reproductive performance in other shrimp species have been studied but the results were not conclusive (Memon et al, 2012;Perez-Velazquez et al, 2002). For example, while certain diets formulated from live feeds were able to improve male reproductive maturation in some shrimp species such as in the male freshwater prawn (Macrobrachium malcolmsonii) (John Samuel et al, 1999), they did not have the same effects in other species such as in the male pink shrimp (Farfantepenaeus paulensis) (Braga et al, 2010) and Litopenaeus vannamei (Perez-Velazquez et al, 2003).…”
