Survivability

A 105 day investigation was conducted to measure the impacts of stocking densities at different ratios of Nile tilapia (Oreochromis niloticus) and common carp (Cyprinus carpio)on their growth and rice yields in rice-fish farming systems. The experiment was conducted by randomized complete block design with three replications. The plot size was 6×3 m, 50 cm height with ditch (3×1 m) for fish. Mean initial weight of O. niloticus was 12.2±1.92 g using three different fish stocking densities (4, 6 and 8 fish m-2) in five different ratios (1:1, 1:0, 0:1, 1:2, 2:1) of O. niloticus and C. carpio. At the end of the investigation specific growth rate, total length (cm), final weight (g), and survival rate (%) for fish were estimated. Plant height and tiller number were also calculated. The study showed that fish growth performance, fish survival rate, plant height, number of tiller, and abundance of plankton were significantly affected by culture system (p<0.05). The final weight was higher in 4 fish m-2 , followed by 6 fish m-2 while the 8 fish m-2 treatment recorded the lowest growth performance. The survival showed the same trend, the highest survival rate was found in C. carpio-O. niloticus ratio of 1:1 (66.67±9.31%) with 6 fish m-2 followed by 4 fish m-2 then by 8 fish m-2 55.36 ±6.11%, and 49.78±4.17% respectively. The highest rice yield, were found in 6 fish m-2 (5.43) that was significantly (p<0.05) higher than in 4 fish m-2 and 8 fish m-2 treatment. The present study revealed that the suitable stocking density was 6 m-2 with 1:1 for C. carpio and O. niloticus for better growth, survival and maximum rice production.

As a brilliant science historian, active ecofeminist, curious multispecies theorist, and passionate storyteller, Donna Haraway has always been interested in exploring ways of relating to "the Other." While her earlier research focused on the possibilities of crossing boundaries between humans and machines (see "Cyborg Manifesto" [1985]) as well as humans and animals (see "Companion Species Manifesto" [2003]), Haraway's most recent book, Staying with the Trouble, urges us to address issues related to the catastrophic environmental crisis, suggesting that the survival of humans and the Earth depends on our ability to engage with each other in a multitude of multispecies assemblages. She argues, "we require each other in unexpected collaborations and combinations, in hot compost piles. We become with each other or not at all" (Staying with the Trouble, 4). A recently released documentary, Donna Haraway: Story Telling for Earthly Survival, produced by Fabrizio Terranova, captures Haraway's lifelong work-and her larger than life personality-inviting the audience to imagine new ways of surviving on a damaged Earth. Like an octopus, Haraway pulls you gently into the spiraling depths of her thinking, and before you know it, you find yourself thinking with and "becoming-with" Haraway and all other critters-human and nonhuman-around you. While the film has been screened across the world since 2016, it reached our doctoral seminar at Arizona State University in the fall of 2018. Aiming to explore the changing role of education in the age of the Anthropocene, we discussed perspec-tival shifts necessary to radically challenge the ideas of human exceptionalism and (neo)liberal individualism to survive on a damaged Earth. The life of all species is, with certainty, at stake in this uncertain time. So how can education contribute to rethinking what it means to be human and resituating the human within the rela-tional flow of life on Earth where everyone and everything-both human and non-human-are always already interconnected? "Beings do not preexist their relatings" (98), 2 and our semester-long encounter with her work created a unique experience of an emergent being-in-relation, a deep entanglement with Haraway and with each other in the context of the impending climate change catastrophe. We found that writing this movie review itself became an embodiment of a unique "becoming-with" experience, enabling us to pick up each other's ideas, play with meanings, and weave For permission to reuse, please contact journalpermissions@press.uchicago.edu.
