macrolepis got negative allometric progress activities. But not, this new b property value the girls was below that of the male. Brand new b value of a man Meters. engeli presented an optimistic allometric gains pattern. Based on this type of progress development research, the analysis indicated that Meters. engeli increases much better than L. macrolepis, and therefore exhibiting you to definitely Yards. engeli is more flexible towards the environment reputation off Lambada Lhok seas. Also, industry observance toward catch constitution of the fishermen presented you to Meters. engeli was also commonplace. New Fulton’s standing factor showed a little difference between K value involving the female and male for both types, in which the K well worth was higher than step 1. According to Morton and you can Routledge 36 , a fish society is actually good shape when the K worth exceeds step one. The study showed that the new K worth of L. macrolepis ranged from a single.sixteen to one.twenty-two, and you may 1.03 to at least one.09 getting Meters. engeli; ergo, one another populations have good shape, from inside the inactive and you may wet season, respectively. At exactly the same time, the newest cousin pounds updates foundation away from both varieties is almost one hundred, demonstrating an equilibrium ranging from victim and you may predator 20 . Such abilities show that these types of seas bring an acceptable restaurants provider of these species. The brand new relative lbs status grounds also represents fish health conditions, inventory rates, and you will administration account 23,thirty five,thirty six,38,39 . Ergo, the new Lambada Lhok seas provide enough eating supply having mullets.

Desk dos. The fresh new b worth, coefficient from correlation and you can dedication, and you can status items from Liza macrolepis dan Moolgarda engeli sampled out-of pling season

The outcomes and exhibited differences in increases models during the dead and you may wet 12 months, and that the seafood grew most readily useful from inside the inactive year. The latest probable cause is the fact www.datingranking.net/ios that waters are unmistakeable and you will an excellent limit rate regarding sunrays permeates on seas, triggering the growth out-of phytoplankton and you will algae. Algae is actually a first food on mullets forty–43 . By contrast, turbidity and you can currents was basically high inside the wet season 44 , and you will and therefore assume so you can restrict the development from phytoplankton and you will algae as vital food having mullets 42,forty five . A comparable trend try advertised from the Chu et al. 29 , just who located a poor growth pattern into the L. macrolepis for the Taiwan through the wintertime, and you may an isometric increases pattern during the summer and you will springtime. More over, Sandhya and you may Shameem 31 observed a terrible progress development from inside the L. macrolepis inside polluted seas, compared with a keen isometric gains development in unpolluted waters. not, an opposite selecting is said for the four types of seafood (Barbus intermedius, Clarias gariepinus, Labeo cylindricus, Oreochromis niloticus baringoensis and you can Protopterus aethiopicu) regarding the River Baringo, Kenya 46 in which these kinds try broadening better during wet-season 46 . Therefore, they determined that seasons inspired notably on the LWRs, however, failed to affect the reputation factor from seafood 46 . An awful development pattern was also stated within the about three species of mullets (Parachelon grandisquamis, Neochelon falcipinnis and you can Mugil cephalus) from the Sombreior Lake, Niger Delta, Nigeria 47 . According to Blackwell mais aussi al. 20 the new Wr excellent to help you estimate fish illnesses, stock, and administration levels of fisheries resources.

According Muchlisin ainsi que al. twenty two , and being affected by environmentally friendly products, the organization trend out of seafood is also influenced by seafood decisions; such as for example, the fresh fish which were productive swimmer had a lower b value than those that were passive swimmers 48–fifty .

An average correlation coefficients regarding L. macrolepis have been 0.93 and you will 0.89 in females and you may boys, correspondingly, while Meters. engeli got a relationship coefficient regarding 0.89 for men and you will 0.93 for ladies. Generally, new relationship coefficients out of L. macrolepis and you can M. engeli include similar (a lot more than 75%), demonstrating an effective correlation anywhere between total length and the body pounds. The determination coefficients from L. macrolepis were 0.85 and you can 0.65 for the male and female fish, respectively, and thus whenever 65%–85% out-of complete variations would be informed me of the design, if you are Meters. engeli had a property value 0.ninety and 0.94 for males and ladies, correspondingly, showing one 90%–94% out of alternatives can be informed me because of the model.
