Effect of diet on growth of the mudspiny lobster Panulirus polyphagus (Herbst, 1793) and the sand lobster Thenus orientalis (Lund, 1793) held in captivity

Abstract

Effect of diet on growth of the mudspiny lobster Panulirus polyphagus J. Mar. Biol. Ass. India, 53 (2), July -December 2011 doi: 10.6024/jmbai.2011.53.2.01665-02 IntroductionA major prerequisite for promoting the candidature of a species for aquaculture is to define the nutritional requirements and feed preferences of the animal in captivity and in the wild, so as to enable the formulation of artificial diets that can serve to maintain the health status of the animal over wide culture periods. Information on the natural diet preferences are available for a few homarid and palinurid adult lobsters (Joll and Phillips, 1984;Junio and Cobb, 1992;Mayfield and Branch, 2000;Goni et al., 2001). The dependance of moulting frequency, and thus growth, on feed has been documented (Stewart and Squires, 1968;Chittleborough, 1974Chittleborough, , 1975Newman and Pollock, 1974). Castell and Budson (1974) described the influence of food on moulting and growth rate in homarid lobsters. Chittleborough (1974)

Population Growth Model and Mortality of Pakistan Lobster (Panulirus polyphagus) in Estuary Waters of Tarakan City

“…While the maximum length growth in female lobsters was found at a size of 31.374 cm with an estimated age of 495 days. This maximum length growth of P. polyphagus in estuarine waters of the Tarakan city was higher than in Sebatik Island waters, North Kalimantan, Indonesia with 12.41 cm (Chodrijah et al 2018), and also in Veraval waters, India, with 13.5 cm for male and 12.47 cm for female (Kizhakudan et al 2013).…”

“…The lobster samples were sorted according to sex. The sex separation was done according to the swimmerets' size or the lobster Field's pleopod (Kizhakudan and Patel 2010;Ikhwanuddin et al 2014). Male lobster is characterized by smaller swimmerets (Ikhwanuddin et al 2014), the presence of gonopore (in juveniles), and a penile process with a hairy tip in adult lobsters (Kizhakudan and Patel 2010).…”

The female lobster is characterized by a bigger swimmerets (Ikhwanuddin et al 2014) and the presence of an ovigerous setae (Kizhakudan and Patel 2010). The male and female ratio of the P. polyphagus population in the estuarine waters of Tarakan City was then calculated by dividing the number of males by the number of females.…”
