macrolepis had bad allometric progress activities. However, the fresh new b property value the newest ladies is below that of the male. The new b worth of a man M. engeli shown a positive allometric increases pattern. Centered on these types of development pattern study, the study indicated that Meters. engeli develops a lot better than L. macrolepis, and so exhibiting one to Meters. engeli is far more versatile on environment standing out-of Lambada Lhok waters. In addition, the field observation on the catch constitution of the fishermen displayed you to definitely M. engeli has also been predominant. This new Fulton’s condition foundation exhibited a small difference in K really worth between your female and male for species, where K well worth was more than step one. Considering Morton and Routledge thirty six , a fish people is actually good condition in the event that K value exceeds step one. The analysis indicated that the fresh K worth of L. macrolepis ranged in one.16 to at least one.twenty-two, and step one.03 to one.09 to possess M. engeli; hence, each other populations come in great condition, from inside the inactive and you can wet-season, correspondingly. In addition, the newest relative pounds updates basis away from each other kinds is close to 100, demonstrating a balance ranging from prey and you can predator 20 . These types of overall performance demonstrate that these types of waters bring an acceptable dinner supply of these species. The latest cousin lbs status factor and additionally represents seafood illnesses, inventory prices, and you may management profile 23,35,thirty-six,38,39 . Thus, brand new Lambada Lhok seas bring enough dinner present for mullets.
Table dos. The brand new b really worth Atheist dating review, coefficient regarding correlation and you can determination, and you will position circumstances off Liza macrolepis dan Moolgarda engeli tested regarding pling season
The outcome plus showed variations in progress habits into the inactive and you can damp year, which this new seafood expanded most useful in the deceased season. Brand new likely need is the fact that waters are obvious and you may a great limitation rate off sunrays permeates into waters, creating the development away from phytoplankton and you may algae. Algae is actually a primary food on mullets forty–43 . In comparison, turbidity and you will currents was in fact higher during the wet-season forty-two , and you can thereby presume so you can inhibit the organization from phytoplankton and alga as vital food item to own mullets 42,45 . The same event try said by Chu mais aussi al. 29 , just who found a negative increases development for the L. macrolepis for the Taiwan while in the wintertime, and you will an isometric gains development in the summertime and you will spring season. Moreover, Sandhya and you will Shameem 31 observed a poor development development when you look at the L. macrolepis during the polluted waters, compared with a keen isometric increases pattern into the unpolluted waters. Although not, an other looking for is actually said inside four species of seafood (Barbus intermedius, Clarias gariepinus, Labeo cylindricus, Oreochromis niloticus baringoensis and you may Protopterus aethiopicu) in the River Baringo, Kenya 46 in which this type of variety is broadening well throughout wet-season 46 . For this reason, it concluded that year affected rather with the LWRs, but failed to impact the condition factor from seafood 46 . A negative gains trend was also reported within the about three types of mullets (Parachelon grandisquamis, Neochelon falcipinnis and you may Mugil cephalus) throughout the Sombreior Lake, Niger Delta, Nigeria 47 . Considering Blackwell ainsi que al. 20 the fresh new Wr is great so you’re able to estimate seafood health issues, inventory, and you will administration levels of fisheries resources.
According Muchlisin ainsi que al. 22 , in addition to struggling with the environmental items, the growth trend regarding fish is even influenced by fish decisions; instance, the fresh new fish which were energetic swimmer got less b value than those that were passive swimmers 48–50 .
The average correlation coefficients from L. macrolepis were 0.93 and you may 0.89 in women and men, respectively, whereas Meters. engeli had a relationship coefficient from 0.89 for men and you can 0.93 for women. In general, brand new correlation coefficients of L. macrolepis and you can M. engeli were equivalent (above 75%), showing a strong relationship ranging from complete size and the body weight. The fresh new determination coefficients of L. macrolepis were 0.85 and you may 0.65 into the men and women fish, respectively, which means whenever 65%–85% out-of complete variations should be told me by the model, whenever you are Yards. engeli had a value of 0.ninety and 0.94 for men and women, respectively, demonstrating one 90%–94% away from variants will be informed me because of the design.
