macrolepis got negative allometric growth designs. However, the fresh new b property value the women try lower than that a man. The latest b worth of the male Yards. engeli showed a positive allometric progress pattern. Considering such development trend study, the analysis indicated that Yards. engeli expands much better than L. macrolepis, and so demonstrating you to definitely M. engeli is more functional for the environmental reputation off Lambada Lhok seas. Furthermore, industry observance with the catch structure of the fishermen showed one M. engeli has also been common. The new Fulton’s updates factor shown a small difference in K worth between the male and female both for types, where the K really worth was greater than step 1. Predicated on Morton and you may Routledge thirty-six , a seafood society is actually good shape when the K really worth is higher than step 1. The study showed that the K property value L. macrolepis ranged from a Crossdresser dating only reviews single.16 to a single.twenty two, and 1.03 to just one.09 for M. engeli; therefore, one another communities come in good shape, when you look at the dry and you can wet season, respectively. At the same time, the newest cousin weight status grounds of both varieties is nearly one hundred, exhibiting a balance anywhere between target and you will predator 20 . These efficiency demonstrate that these waters bring a sufficient eating resource of these types. The new relative pounds condition factor as well as represents seafood illnesses, inventory rates, and you may government profile 23,thirty-five,thirty-six,38,39 . Ergo, the fresh new Lambada Lhok seas give sufficient dining supply to own mullets.
Desk dos. Brand new b worth, coefficient from correlation and you may determination, and you may updates factors out-of Liza macrolepis dan Moolgarda engeli sampled regarding pling year
The outcome together with shown differences in increases activities into the dead and wet year, and that the fish increased most useful in the dry 12 months. The likely reason is the fact that the seas are unmistakeable and an effective maximum speed out of sun penetrates for the waters, creating the growth of phytoplankton and you may algae. Alga are a first food item to the mullets 40–43 . In comparison, turbidity and currents was basically higher inside the wet season forty two , and you may thereby assume so you’re able to prevent the organization of phytoplankton and you can algae as essential meal having mullets 42,forty five . A comparable phenomenon try advertised by Chu et al. 29 , which discovered a bad progress development in L. macrolepis during the Taiwan during cold temperatures, and you can an enthusiastic isometric progress development in the summer and you may spring. Additionally, Sandhya and you may Shameem 31 observed a bad growth pattern from inside the L. macrolepis in polluted waters, in contrast to an isometric development development in unpolluted oceans. not, an other finding was reported when you look at the five species of seafood (Barbus intermedius, Clarias gariepinus, Labeo cylindricus, Oreochromis niloticus baringoensis and you can Protopterus aethiopicu) about River Baringo, Kenya 46 in which this type of variety is broadening really during wet-season 46 . Thus, it figured year inspired significantly into the LWRs, but didn’t affect the reputation foundation out-of seafood 46 . An awful gains development was also advertised from inside the three types of mullets (Parachelon grandisquamis, Neochelon falcipinnis and you will Mugil cephalus) about Sombreior Lake, Niger Delta, Nigeria 47 . Considering Blackwell ainsi que al. 20 the latest Wr is good to imagine seafood illnesses, inventory, and you may management degrees of fisheries resources.
According Muchlisin et al. twenty-two , and being affected by environmentally friendly facts, the growth pattern away from fish is even dependent on seafood behavior; such, the new seafood that have been productive swimmer had a lower life expectancy b worth as opposed to those that have been passive swimmers forty eight–fifty .
The typical relationship coefficients out of L. macrolepis were 0.93 and you can 0.89 in women and you may people, respectively, whereas M. engeli got a correlation coefficient out of 0.89 for males and you will 0.93 for ladies. Typically, brand new correlation coefficients off L. macrolepis and Yards. engeli is equivalent (more than 75%), appearing an effective relationship between complete length and body weight. The newest devotion coefficients from L. macrolepis was indeed 0.85 and you will 0.65 to your female and male fish, correspondingly, and therefore just as much as 65%–85% out-of total variations should be said from the design, if you’re Yards. engeli had a worth of 0.90 and you will 0.94 for men and female, respectively, indicating one ninety%–94% out of versions should be informed me because of the model.
